I have a Logitech Quickcam 3500 attached to my system. The camera is brand new and worked up to a few days ago. Now, when I want to use it, I get either a totally black image or a bunch of scanlines. Also, the activity light on the camera fails to come on when checked in Kopete for instance.
The system is running openSUSE 11 with both KDE 3.5 and KDE 4, fully up to date.
The device is seen by the system, as proven by lsusb:
Bus 005 Device 005: ID 046d:09a4 Logitech, Inc.
The uvcvideo module is loaded for this camera, and I believe that to be correct.
# lsmod | grep uvc uvcvideo * * * * * * * 73864 *3 compat_ioctl32 * * * * 17664 *1 uvcvideo videodev * * * * * * * 48000 *4 uvcvideo v4l1_compat * * * * * *29572 *2 uvcvideo,videodev usbcore * * * * * * * 164812 *8 usbhid,snd_usb_audio,snd_usb_lib,uvcvideo,usb_storage,ehci_hcd,uhci_hcd
*Dmesg tells me this:
# dmesg | grep uvc uvcvideo: Found UVC 1.00 device <unnamed> (046d:09a4) uvcvideo: Failed to query (135) UVC control 1 (unit 0) : -110 (exp. 26). usbcore: registered new interface driver uvcvideo
I then tried a program called luvcview. That gives me this:
# luvcview luvcview 0.2.4 SDL information: * Video driver: x11 * A window manager is available Device information: * Device path: */dev/video0 Stream settings: * Frame format: MJPG Unable to set format: Device or resource busy *Init v4L2 failed !! exit fatal
Googling for this issue hasn’t produced much in the way of additional troubleshooting steps. I have tested the camera by hooking it up to a Wintendo box and that does produce an image, so I know the camera is not broken, it is a Linux problem. Is there anything else I can do?
