Subject: Change std::wstring to std::string in DeviceInfo

For easier handling, we should use a std::string instead of
std::wstring for the serial number in DeviceInfo.  For the conversion, I
assume that the serial number is valid UTF-8.  As it should be
alphanumeric and ASCII only, this should be true.
