--- Comment #3 from Alan Stern (stern@rowland.harvard.edu) ---
The code _does_ make this check. See usb_submit_urb(); near the start it does:
ep = usb_pipe_endpoint(dev, urb->pipe);
if (!ep)
return -ENOENT;
Now if you want to make this a little clearer, you could submit a patch that
changes the code in qh_urb_transaction() to do this:
maxpacket = usb_endpoint_maxp(&urb->ep->desc);
