Hi, I'm experiencing some difficulty with the Logitech Sphere AF. (I can temporarily reset the camera by removing the uvcvideo and snd_usb_audio modules from the kernel). Details below:
Chris I'm running openSuSE 11.1, SuSE kernel 2.6.27.21-0.1-default, if it would help I can update the module to the latest version from the project page. I have added the following line to modprobe.conf.local - which initially allows the video and audio to function: install uvcvideo /sbin/modprobe snd_usb_audio; /sbin/modprobe --ignore-install uvcvideo The system is showing spontaneous 'USB disconnects' at random intervals (e.g. the first disconnect below). I also notice 'Failed to query ... control ...' from uvcvideo. dmesg: usb 4-4: new high speed USB device using ehci_hcd and address 2 usb 4-4: configuration #1 chosen from 1 choice usb 4-4: New USB device found, idVendor=046d, idProduct=0994 usb 4-4: New USB device strings: Mfr=0, Product=0, SerialNumber=2 usb 4-4: SerialNumber: BB56BCEC Linux video capture interface: v2.00 usbcore: registered new interface driver snd-usb-audio uvcvideo: Found UVC 1.00 device <unnamed> (046d:0994) input: UVC Camera (046d:0994) as /devices/pci0000:00/0000:00:1d.7/usb4/4-4/4-4:1.0/input/input8 usbcore: registered new interface driver uvcvideo USB Video Class driver (v0.1.0) uvcvideo: Failed to query (135) UVC control 2 (unit 2) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 7 (unit 2) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 3 (unit 2) : -110 (exp. 2). usb 4-4: USB disconnect, address 2 ALSA sound/usb/usbaudio.c:351: frame 0 active: -71 ALSA sound/usb/usbaudio.c:696: cannot submit urb (err = -19) ALSA sound/usb/usbaudio.c:868: cannot submit datapipe for urb 0, error -19: no device <repeated many times...> ALSA sound/usb/usbaudio.c:868: cannot submit datapipe for urb 0, error -19: no device Subsequent physical replugging of the camera leads to events like these: usb 4-4: new high speed USB device using ehci_hcd and address 3 usb 4-4: configuration #1 chosen from 1 choice uvcvideo: Found UVC 1.00 device <unnamed> (046d:0994) input: UVC Camera (046d:0994) as /devices/pci0000:00/0000:00:1d.7/usb4/4-4/4-4:1.0/input/input9 usb 4-4: New USB device found, idVendor=046d, idProduct=0994 usb 4-4: New USB device strings: Mfr=0, Product=0, SerialNumber=2 usb 4-4: SerialNumber: BB56BCEC uvcvideo: Failed to query (130) UVC control 2 (unit 2) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 7 (unit 2) : -110 (exp. 2). uvcvideo: Failed to query (135) UVC control 3 (unit 2) : -110 (exp. 2).
