   started qjackctl after the device was plugged in,

   starting jack manually seems to be working (also tested wiuth
ardour2, both recording and playback works).

   Does that mean there is a bug in qjackctl? Using the version in
Ubuntu 13.04 which is qjackctl 0.3.9-2

   Here's what jackd prints out when started manually:
