What does your > ps say, and also, is there anything interesting in dmesg? I don't think anything has crashed, because if I terminate the application that is using the audio device things unlock nicely. I suspect that the device-specific code for removing the audio/hid part of the headset is blocking until the number of users drop to 0. And I guess that makes the entire usb hotplug mechanism stall. I don't have access to that machine until Monday, but I noticed that the mouse doesn't get powered on until I unlock everything by killing the audio application. I can tell because the LED/optical sensor on the mouse is disabled. I was just about to throw away the mouse the first time this happened! =) My main question is that if the current behaviour is sane or not. I think not.
