    I didn't follow it, because it was not relative to the driver. Besides, we
    didn't focus on -EPROTO at that time, because it was not the major issue.
    And the -EPROTO occurred rarely indeed during a lot of transmission.
    The hw engineer confirmed that the device completed the transfer
    normally, but the driver still got an error from the host. I don't sure if
    there was a USB HUB between the device and the USB host controller.
    That are all what I know.

    Best Regards,
    Hayes
