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?
