As noted on line 1071:
If you hit this BUG() it's likely a problem
with some driver's disconnect() routine.
Leading naturally to Greg's "what drivers were active?" question ...
... though I wonder if the way uhci.c works, it might not leave the
qh->dev field valid rather "late" after unlinking associated URBs.
That'd be fine, except uhci_free_dev() doesn't ensure that such
device state is all gone. (No such logic in usb-uhci.c either.)
