adb: fix for SuperSpeed devices
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.
