QuickCam Express Karmic

Asked by lptester

Camera driver qc-usb-source installed with synaptic package manager. Cheese detects camera but resolution box is blank in preferences window, Video display is an active colour test pattern with small rectangular frame in lower right corner showing B/W static. Cheese also detects ATI TV Tuner card and displays active video stream.

Cheese -v script is:

Found device 046d:0870, getting capabilities...
Detected v4l2 device: Camera
Driver: STV06xx, version: 132608
Capabilities: 0x05000001

Partial dmesg script is:

gspca configuration error (28) may be the problem. Suggestions to get camera to function correctly would be appreciated.

Thanks for your inputs. The listed driver for camera 046d:0870 is qc-usb and this is installed.
Cheese detects this camera but the display is just a test screen picture.

Can someone confirm they have this camera and driver working with cheese.
Thanks

The error message "gspca: usb_submit_urb [0] err -28"
turned out to be a usb bandwidth issue preventing the camera display.
The solution was to plug the camera directly into the PCI usb2.0 card instead of using a hub.
