 Based on this mail, I believe the PR should close. It appears to be
 resolved in current/4.x. -The stall is probably something to be tracked
 in another PR.
 (I sent the h/w to Matthias)

 I believe I've found what caused these crashes and why I couldn't
 reproduce them: The "poll" function checks the endpoint type in the
 endpoint descriptor, but the ikey does use the default "control
 endpoint" which no descriptor exists for.
 An unrelated change (addition of read-ahead) changed the order
 of checks so that the code in question is not reached. So -current
 (and 4.x) are OK. From code inspection, 3.x is still affected.
 Since the read-ahead stuff is too complex to be pulled up to 3.x;
 we'll need a simpler patch.
 (btw, the "stall after a while" with my USB2 hub seems to be a subtle
 timing problem rather than a toggle bit bug. It disappears as soon
 as I add some debug printouts.)
