Hi! I have a Labtec 712 USB Headset. When I plug it in, it is discovered correctly and I can use it. But after a few seconds or minutes, the music stops playing and XMMS hangs. I can't SIGKILL xmms nor rmmod the snd-usb-audio module, so I unplugged the Headset. The only way to get rid of the dead process or the crashed snd-usb-audio module is rebooting the computer
What could this be? I'm using Kernel 2.6.6 w/ Alsa 1.0.4 (The problem appeared with 2.6.5+kernel Alsa, too), Debian sid and ECS K7S5A Mainboard. Attached, there are the last words from my kernel. Ciao Martin
