Dan and Sarah, what do you make of this? Seems like it could be related to the non-superspeed enumeration problems you've been working on during the fall. Ben, you mentioned trying Sarah's fun-2013-10-01-address-device branch. Were you able to get the device to enumerate consistently with that or did it only work sometimes (as also seems to be the case with usb-next)?
