Description of problem:

My web cam, a Logitech Quickcam Pro 4000, does not work on Fedora 13. I tried running the basic test at

The test failed. When I open cheese, it shows an animation that I believe indicates it is initializing the webcam, but then I just get a black image (yes, I lifted the lens cover on the webcam). :^) 

Version-Release number of selected component (if applicable):

$ rpm -qa | grep v4l

How reproducible:

Run the program 'cheese' while the webcam is plugged into a USB port. The 'camorama' program also will not display an image.

Steps to Reproduce:
1. Boot the machine and login
2. Plug in the webcam
3. Menu -> Sound & Video -> Cheese
Actual results:

The window that should be displaying the webcam image is completely black.

Expected results:

I expect to see an image of whatever the webcam is aimed at.

Additional info:

$ rpm -qa | grep cheese

Thanks for the bug report.

I have such a camera myself, and I can reproduce this. Try starting cheese again, or unplugging and re-plugging the camera, that usually fixes it. I'm afraid I don't have an easy way to properly fix this.

The pwc driver which this camera uses is not in good state and is not actively maintained atm. I've put re-writing it on my todo list. But that is something which need to happen upstream, not in Fedora. So I'm going to close this bug with a resolution of upstream.
