By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

HIDAPI can be either built as a shared library (.so or .dll) or +can be embedded directly into a target application by adding a single source +file (per platform) and a single header. + +HIDAPI has four back-ends: + * Windows (using hid.dll) + * Linux/hidraw (using the Kernel's hidraw driver) + * Linux/libusb (using libusb-1.0) + * FreeBSD (using libusb-1.0) + * Mac (using IOHidManager) + +On Linux, either the hidraw or the libusb back-end can be used. There are +tradeoffs, and the functionality supported is slightly different. + +Linux/hidraw (linux/hid.c): +This back-end uses the hidraw interface in the Linux kernel. While this +back-end will support both USB and Bluetooth, it has some limitations on +kernels prior to 2.6.39, including the inability to send or receive feature +reports. In addition, it will only communicate with devices which have +hidraw nodes associated with them. Keyboards, mice, and some other devices +which are blacklisted from having hidraw nodes will not work. Fortunately, +for nearly all the uses of hidraw, this is not a problem. + +Linux/FreeBSD/libusb (libusb/hid.c): +This back-end uses libusb-1.0 to communicate directly to a USB device. This +back-end will of course not work with Bluetooth devices. + +HIDAPI also comes with a Test GUI. The Test GUI is cross-platform and uses +Fox Toolkit (http://www.fox-toolkit.org). It will build on every platform +which HIDAPI supports. Since it relies on a 3rd party library, building it +is optional but recommended because it is so useful when debugging hardware. + +What Does the API Look Like? +============================= +The API provides the the most commonly used HID functions including sending +and receiving of input, output, and feature reports. The sample program, +which communicates with a heavily hacked up version of the Microchip USB +Generic HID sample looks like this (with error checking removed for +simplicity): + +#ifdef WIN32 +#include +#endif +#include +#include +#include "hidapi.h" + +#define MAX_STR 255 + +int main(int argc, char* argv[]) +{ + int res; + unsigned char buf[65]; + wchar_t wstr[MAX_STR]; + hid_device *handle; + int i; + + // Initialize the hidapi library + res = hid_init(); + + // Open the device using the VID, PID, + // and optionally the Serial number. + handle = hid_open(0x4d8, 0x3f, NULL); + + // Read the Manufacturer String + res = hid_get_manufacturer_string(handle, wstr, MAX_STR); + wprintf(L"Manufacturer String: %s\n", wstr); + + // Read the Product String + res = hid_get_product_string(handle, wstr, MAX_STR); + wprintf(L"Product String: %s\n", wstr); + + // Read the Serial Number String + res = hid_get_serial_number_string(handle, wstr, MAX_STR); + wprintf(L"Serial Number String: (%d) %s\n", wstr[0], wstr); + + // Read Indexed String 1 + res = hid_get_indexed_string(handle, 1, wstr, MAX_STR); + wprintf(L"Indexed String 1: %s\n", wstr); + + // Toggle LED (cmd 0x80). The first byte is the report number (0x0). + buf[0] = 0x0; + buf[1] = 0x80; + res = hid_write(handle, buf, 65); + + // Request state (cmd 0x81). The first byte is the report number (0x0). + buf[0] = 0x0; + buf[1] = 0x81; + res = hid_write(handle, buf, 65); + + // Read requested state + res = hid_read(handle, buf, 65); + + // Print out the returned buffer. + for (i = 0; i < 4; i++) + printf("buf[%d]: %d\n", i, buf[i]); + + // Finalize the hidapi library + res = hid_exit(); + + return 0; +} + +If you have your own simple test programs which communicate with standard +hardware development boards (such as those from Microchip, TI, Atmel, +FreeScale and others), please consider sending me something like the above +for inclusion into the HIDAPI source. This will help others who have the +same hardware as you do. + +License +======== +HIDAPI may be used by one of three licenses as outlined in LICENSE.txt. + +Download +========= +HIDAPI can be downloaded from github + git clone git://github.com/signal11/hidapi.git + +Build Instructions +=================== + +This section is long. Don't be put off by this. It's not long because it's +complicated to build HIDAPI; it's quite the opposite. This section is long +because of the flexibility of HIDAPI and the large number of ways in which +it can be built and used. You will likely pick a single build method. + +HIDAPI can be built in several different ways. If you elect to build a +shared library, you will need to build it from the HIDAPI source +distribution. If you choose instead to embed HIDAPI directly into your +application, you can skip the building and look at the provided platform +Makefiles for guidance. These platform Makefiles are located in linux/ +libusb/ mac/ and windows/ and are called Makefile-manual. In addition, +Visual Studio projects are provided. Even if you're going to embed HIDAPI +into your project, it is still beneficial to build the example programs. + + +Prerequisites: +--------------- + + Linux: + ------- + On Linux, you will need to install development packages for libudev, + libusb and optionally Fox-toolkit (for the test GUI). On + Debian/Ubuntu systems these can be installed by running: + sudo apt-get install libudev-dev libusb-1.0-0-dev libfox-1.6-dev + + If you downloaded the source directly from the git repository (using + git clone), you'll need Autotools: + sudo apt-get install autotools-dev autoconf automake libtool + + FreeBSD: + --------- + On FreeBSD you will need to install GNU make, libiconv, and + optionally Fox-Toolkit (for the test GUI). This is done by running + the following: + pkg_add -r gmake libiconv fox16 + + If you downloaded the source directly from the git repository (using + git clone), you'll need Autotools: + pkg_add -r autotools + + Mac: + ----- + On Mac, you will need to install Fox-Toolkit if you wish to build + the Test GUI. There are two ways to do this, and each has a slight + complication. Which method you use depends on your use case. + + If you wish to build the Test GUI just for your own testing on your + own computer, then the easiest method is to install Fox-Toolkit + using ports: + sudo port install fox + + If you wish to build the TestGUI app bundle to redistribute to + others, you will need to install Fox-toolkit from source. This is + because the version of fox that gets installed using ports uses the + ports X11 libraries which are not compatible with the Apple X11 + libraries. If you install Fox with ports and then try to distribute + your built app bundle, it will simply fail to run on other systems. + To install Fox-Toolkit manually, download the source package from + http://www.fox-toolkit.org, extract it, and run the following from + within the extracted source: + ./configure && make && make install + + Windows: + --------- + On Windows, if you want to build the test GUI, you will need to get + the hidapi-externals.zip package from the download site. This + contains pre-built binaries for Fox-toolkit. Extract + hidapi-externals.zip just outside of hidapi, so that + hidapi-externals and hidapi are on the same level, as shown: + + Parent_Folder + | + +hidapi + +hidapi-externals + + Again, this step is not required if you do not wish to build the + test GUI. + + +Building HIDAPI into a shared library on Unix Platforms: +--------------------------------------------------------- + +On Unix-like systems such as Linux, FreeBSD, Mac, and even Windows, using +Mingw or Cygwin, the easiest way to build a standard system-installed shared +library is to use the GNU Autotools build system. If you checked out the +source from the git repository, run the following: + + ./bootstrap + ./configure + make + make install <----- as root, or using sudo + +If you downloaded a source package (ie: if you did not run git clone), you +can skip the ./bootstrap step. + +./configure can take several arguments which control the build. The two most +likely to be used are: + --enable-testgui + Enable build of the Test GUI. This requires Fox toolkit to + be installed. Instructions for installing Fox-Toolkit on + each platform are in the Prerequisites section above. + + --prefix=/usr + Specify where you want the output headers and libraries to + be installed. The example above will put the headers in + /usr/include and the binaries in /usr/lib. The default is to + install into /usr/local which is fine on most systems. + +Building the manual way on Unix platforms: +------------------------------------------- + +Manual Makefiles are provided mostly to give the user and idea what it takes +to build a program which embeds HIDAPI directly inside of it. These should +really be used as examples only. If you want to build a system-wide shared +library, use the Autotools method described above. + + To build HIDAPI using the manual makefiles, change to the directory + of your platform and run make. For example, on Linux run: + cd linux/ + make -f Makefile-manual + + To build the Test GUI using the manual makefiles: + cd testgui/ + make -f Makefile-manual + +Building on Windows: +--------------------- + +To build the HIDAPI DLL on Windows using Visual Studio, build the .sln file +in the windows/ directory. + +To build the Test GUI on windows using Visual Studio, build the .sln file in +the testgui/ directory. + +To build HIDAPI using MinGW or Cygwin using Autotools, use the instructions +in the section titled "Building HIDAPI into a shared library on Unix +Platforms" above. Note that building the Test GUI with MinGW or Cygwin will +require the Windows procedure in the Prerequisites section above (ie: +hidapi-externals.zip). + +To build HIDAPI using MinGW using the Manual Makefiles, see the section +"Building the manual way on Unix platforms" above. + +HIDAPI can also be built using the Windows DDK (now also called the Windows +Driver Kit or WDK). This method was originally required for the HIDAPI build +but not anymore. However, some users still prefer this method. It is not as +well supported anymore but should still work. Patches are welcome if it does +not. To build using the DDK: + + 1. Install the Windows Driver Kit (WDK) from Microsoft. + 2. From the Start menu, in the Windows Driver Kits folder, select Build + Environments, then your operating system, then the x86 Free Build + Environment (or one that is appropriate for your system). + 3. From the console, change directory to the windows/ddk_build/ directory, + which is part of the HIDAPI distribution. + 4. Type build. + 5. You can find the output files (DLL and LIB) in a subdirectory created + by the build system which is appropriate for your environment. On + Windows XP, this directory is objfre_wxp_x86/i386. + +Cross Compiling +================ + +This section talks about cross compiling HIDAPI for Linux using autotools. +This is useful for using HIDAPI on embedded Linux targets. These +instructions assume the most raw kind of embedded Linux build, where all +prerequisites will need to be built first. This process will of course vary +based on your embedded Linux build system if you are using one, such as +OpenEmbedded or Buildroot. + +For the purpose of this section, it will be assumed that the following +environment variables are exported. + + $ export STAGING=$HOME/out + $ export HOST=arm-linux + +STAGING and HOST can be modified to suit your setup. + +Prerequisites +-------------- + +Note that the build of libudev is the very basic configuration. + +Build Libusb. From the libusb source directory, run: + ./configure --host=$HOST --prefix=$STAGING + make + make install + +Build libudev.

One (linux/hid.c) uses the +Linux hidraw driver, and the other (libusb/hid.c) uses libusb. Which one you +use depends on your application. Complete functionality of the hidraw +version depends on patches to the Linux kernel which are not currently in +the mainline. These patches have to do with sending and receiving feature +reports. The libusb implementation uses libusb to talk directly to the +device, bypassing any Linux HID driver. The disadvantage of the libusb +version is that it will only work with USB devices, while the hidraw +implementation will work with Bluetooth devices as well. + +To use HIDAPI, simply drop either linux/hid.c or libusb/hid.c into your +application and build using the build parameters in the Makefile. + + +Libusb Implementation notes +---------------------------- +For the libusb implementation, libusb-1.0 must be installed. Libusb 1.0 is +different than the legacy libusb 0.1 which is installed on many systems. To +install libusb-1.0 on Ubuntu and other Debian-based systems, run: + sudo apt-get install libusb-1.0-0-dev + + +Hidraw Implementation notes +---------------------------- +For the hidraw implementation, libudev headers and libraries are required to +build hidapi programs. To install libudev libraries on Ubuntu, +and other Debian-based systems, run: + sudo apt-get install libudev-dev + +On Redhat-based systems, run the following as root: + yum install libudev-devel + +Unfortunately, the hidraw driver, which the linux version of hidapi is based +on, contains bugs in kernel versions < 2.6.36, which the client application +should be aware of. + +Bugs (hidraw implementation only): +----------------------------------- +On Kernel versions < 2.6.34, if your device uses numbered reports, an extra +byte will be returned at the beginning of all reports returned from read() +for hidraw devices. This is worked around in the libary. No action should be +necessary in the client library. + +On Kernel versions < 2.6.35, reports will only be sent using a Set_Report +transfer on the CONTROL endpoint. No data will ever be sent on an Interrupt +Out endpoint if one exists. This is fixed in 2.6.35. In 2.6.35, OUTPUT +reports will be sent to the device on the first INTERRUPT OUT endpoint if it +exists; If it does not exist, OUTPUT reports will be sent on the CONTROL +endpoint. + +On Kernel versions < 2.6.36, add an extra byte containing the report number +to sent reports if numbered reports are used, and the device does not +contain an INTERRPUT OUT endpoint for OUTPUT transfers. For example, if +your device uses numbered reports and wants to send {0x2 0xff 0xff 0xff} to +the device (0x2 is the report number), you must send {0x2 0x2 0xff 0xff +0xff}. If your device has the optional Interrupt OUT endpoint, this does not +apply (but really on 2.6.35 only, because 2.6.34 won't use the interrupt +out endpoint). diff --git a/linux/hid.c b/linux/hid.c new file mode 100644 index 0000000..56dac0f --- /dev/null +++ b/linux/hid.c @@ -0,0 +1,797 @@ +/******************************************************* + HIDAPI - Multi-Platform library for + communication with HID devices. + + Alan Ott + Signal 11 Software + + 8/22/2009 + Linux Version - 6/2/2009 + + Copyright 2009, All Rights Reserved. + + At the discretion of the user of this library, + this software may be licensed under the terms of the + GNU General Public License v3, a BSD-Style license, or the + original HIDAPI license as outlined in the LICENSE.txt, + LICENSE-gpl3.txt, LICENSE-bsd.txt, and LICENSE-orig.txt + files located at the root of the source distribution. + These files may also be found in the public source + code repository located at: + http://github.com/signal11/hidapi . +********************************************************/ + +/* C */ +#include +#include +#include +#include +#include + +/* Unix */ +#include +#include +#include +#include +#include +#include +#include + +/* Linux */ +#include +#include +#include +#include + +#include "hidapi.h" + +/* Definitions from linux/hidraw.h.

It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC to any special C compiler that is needed for +# multi-threaded programs (defaults to the value of CC otherwise). (This +# is necessary on AIX to use the special cc_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also link it with them as well. e.g. you should link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threads programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name +# (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +# PTHREAD_PRIO_INHERIT symbol is defined when compiling with +# PTHREAD_CFLAGS. +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository.
