On http://linux-uvc.berlios.de/, there are two problems listed. I want to really fix these two problems so the camera will just work after plugging in (and not disconnect). I started with problem no. 2 as this causes the camera not to work at all when plugged in: usb 5-2.4: new high speed USB device using ehci_hcd and address 7 usb 5-2.4: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device (046d:08c3) uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround. uvcvideo: Failed to query (129) UVC probe control : -110 (exp. 26). uvcvideo: Failed to initialize the device (-5). When I do "modprobe snd_usb_audio", then "rmmod snd_usb_audio" and finally "modprobe uvcvideo", it works. So it looks like snd_usb_audio does some initialization that allows uvcvideo to work. It didn't work at all I didn't have snd_usb_audio module compiled. What was the change that supposedly broke this in 2.6.22? -- Ondrej Zary
