-                   parsing the HID Report descriptor. Getting a HID Report
-                   descriptor involves claiming the interface. Claiming
-                   the interface involves detaching the kernel driver. Detaching
-                   the kernel driver is hard on the system because
-                   it will unclaim interfaces (if another app has them claimed)
-                   and the re-attachment of the driver will
-                   sometimes change /dev entry names. It is for these reasons
-                   that this section is #if 0. For composite devices,
-                   use the interface field in the hid_device_info struct to
