 It shouldn't. But presumably there's one or more problems such that
 some set of responses a device can make that puts the USB stack into a
 broken state, and then everything else is going to go down the drain
 too (slowly, or not so slowly, depending)... it would be good to
 figure out what, because infinite loops of "umass: BBB reset failed"
 and so forth appear in quite a few PRs.
