    xHCI 1.0: Incompatible Device Error · f6ba6fe2
    Alex He authored
    It is one new TRB Completion Code for the xHCI spec v1.0.
    Asserted if the xHC detects a problem with a device that does not allow it to
    be successfully accessed, e.g. due to a device compliance or compatibility
    problem. This error may be returned by any command or transfer, and is fatal
    as far as the Slot is concerned. Return -EPROTO by urb->status or frame->status
    of ISOC for transfer case. And return -ENODEV for configure endpoint command,
    evaluate context command and address device command if there is an incompatible
    Device Error. The error codes will be sent back to the USB core to decide how
    to do. It's unnecessary for other commands because after the three commands run
    successfully means that the device has been accepted.
