Large HID descriptors are parsed incorrectly #114

Closed GamePad64 closed 11 months ago

GamePad64 commented 11 months ago

HID descriptor size is uint16, so getting its size as buf[7] returns incorrect results, if HID descriptor is large enough.

Have you got a link to the spec handy? We can fix for the next release.
