Not sure if I'm seeing the same problem, but it sounds like it might be. My midi controller (keystation) works fine for day after day of minimal use, and then one day I'll go to use it and it doesn't work. qjackctl sees it and can establish connections, dmesg reports nothing unusual. It just doesn't seem to be generating any events. I unplug its usb and it disappears from qjackctl. I plug it back in and it reappears, but still doesn't work. So I unplug the power and plug it back in, same thing. So I unload snd-usb-audio and unplug the usb and plug it back in and the same thing. Finally I give up and reboot. Yesterday after rebooting, it still didn't work, so I unplugged all my USB devices (keyboard, mouse, scanner, keystation) and plugged the keystation back in, and then it worked. Very frustrating and since dmesg doesn't say anything interesting and afaict alsa things it's fine, I don't know where to look for more information. 2.6.13-rt13, and the problem has been around for ages. -- Hans Fugal ; http://hans.fugal.net There's nothing remarkable about it. All one has to do is hit the right keys at the right time and the instrument plays itself. -- Johann Sebastian Bach -------------- next part -------------- A non-text attachment was scrubbed...
