[LAU] M-audio keyrig 49 not seen by QJackCtrl

Hi list, Since update to Debian 6.0.1, everything from the stable repos, the usb midi kbd don't work anymore. Have search the web and here, but can't find anything. It seems that the kbd is seen by the machine, but not in QJack. Have tried with and without the midisport-firmware and it's the same. dmesg says it has a problem with snd_usb_audio, but my limit is just here, before the modules and kernel stuff... Any help really appreciate ! some console outputs : f@f:~$ dmesg | grep usb .....
