I was debugging Logitech C910 webcam. 1. 'kldload snd_uaudio' while camera was attached 2. ran webcamd, which worked 3. stopped webcamd 4. 'kldunload snd_uaudio' while the camera is still attached => hanged in D+ 5. 'kldstat' also hangs in D+ I didn't really use usound, just loaded the module. What is wrong with snd_uaudio? Yuri
