--- Comment #3 from Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) ---
The problem is not that usb_set_interface() does inadequate checking; the
problem is that the uvc_video driver calls usb_set_interface() at an
inappropriate time -- i.e., after its remove routine has returned.

(I don't know this for certain, but it seems likely given the context of the
bug.)
