Evidently this bug is pretty difficult to get hold of. There has to be an URB that is unlinked at the time the endpoint gets disabled, and ideally it should have failed with a communications error (because the device was unplugged). Going to the trouble to arrange all that doesn't seem worthwhile. On the whole we shouldn't need to worry about it -- except that I think the patch itself is worthwhile, pending review by David.
