    USB - Add support for xfer-restart-before-callback
    Interrupt pipes restart their xfers.  When used for a USB
    keyboard the xfer must be restarted before the callback,
    even though there may be state data races, otherwise
    the CTL-ALT-ESC sequence into the debugger will leave
    the xfer unqueued and the keyboard will stop working.
