Thinking about this again, are you sure the read urb depends on the control message? It's quite easy to test, just a add a long timeout after the read URB was sent (say, five minutes) and waits for the read urb callback to run. If it ran _before_ the timeout expires with no timeout error it does not depend. Then we can do the simpler solution: just kill the read urb in the ipaq_open's error path. -- Luiz Fernando N.
