So queueing the URBs to the control-ep wouldn't help you anyway (besides it's not there at least for *uhci*, IIRC). > Now here comes my question: How do I wait? Why not simply preparing _and_ submitting the next URB when the former one completes, i.e. let the completion handler do that. After successful submission the completion handler could wake_up() the main thread so it can go on. In order to prevent races there, one might want to use the wait_event() macro, if appropriate.
