    CVE: NA
    
    ----------------------------------------------------------------------
    
    When the current HiSilicon USB xhci controller formats the faulty
    U disk, it will trigger a controller exception error. This will
    cause errors in the control logic of the xhci controller and
    driver software. In the end, all USB devices on the xhci controller
    cannot be used.
    
    By introducing a noop command operation, restore the logic of the
    xhci controller and driver software, and restore all USB devices
    on the xhci controller to normal.
