Don't hang the system if an urb is submitted on a non-existant endpoint. Should probably be checked higher up, but this is where I hit it.
In fact it'd be good if you can find out why exactly the version of this test the usb_submit_urb() code (core/urb.c) wasn't catching this for you ... was something trashing memory, maybe?
