Unfortunately there was no existing artwork for USBD_SHORT_XFER_OK for ehci 
(which I believe would be closer to xhci).

Unfortunatley the only inbound errors I've had with urtwn(4) and xhci have 
been due to a faulty usb hub for which sending data was ok but all errors on 
receiving data.


Sorry I cannot be of more help with this.
