(**) This is also one of several codes that different kinds of host controller use to indicate a transfer has failed because of device disconnect. In the interval before the hub driver starts disconnect processing, devices may receive such fault reports for every request. > Ok, this is not a big issue because I can use vlc to test the camera.
