The USB descriptor parsing in adb fails to detect SuperSpeed devices because of the SuperSpeed Endpoint Companion Descriptor. This cherry-picks the upstream fix for the problem.
Unfortunately there never were a release with this fix before the conversion to C++, so upgrading to a newer version isn't an option. This makes adb work with SuperSpeed devices like the Sierra Wireless EM7565. Tested and verified.
