The URBs +are processed in the reverse temporal order they were submitted. +This is similar to usb_kill_anchored_urbs(), but it will not sleep. +Therefore no guarantee is made that the URBs have been unlinked when +the call returns.

Its return value will tell you whether the timeout was reached. + + |
