The upper layer will not send any packets downstream (i.e.
call pegasus_start_xmit()) because netif_wake_queue() is called
only from the completion handler.

nope. reseting this particular device is not easy with the existing
urb scheduling mechanism and the driver ended up just not doing it
during the normal work process. :-)
