I have the same doubt. Can you explain how/why firmware uploading and
btusb_open() overlap, and how this is avoided with your patch?
If they do overlap, is that not a bug in the stack that should be fixed instead?
If the fix belongs in btusb and this BTUSB_RESET_RESUME thing really
is problematic, should it be totally removed instead?
