I think this is of usb device failure, but the bigest problem is that blocked hang. There isn't any cable except wiretraces on motherboard :D.
That device is like: http://www.aradasystems.com/Upload/ProductImages/128835373116845000image_usb_dongle.jpg and connected dirrectly to
the usb port, which is inside server case.
