Hi,

Given that the same problem shows up in all the different programs you tried, this is likely a kernel problem -> changing the component to kernel.

For starters, we need to know what camera you have, can you run lsusb in a terminal and copy and paste the output here?

Regards,

Hans

Dear Hans,

This morning I plugged in a very old Logitech Quickcam for Notebooks Pro camera and it works just fine. The camera I am having trouble with (that I did not have trouble with last week on Fedora 16) is a RocketFish HD Webcam Model # RF-HDWEB. I am not sure who makes RocketFish products. The lsusb output reports that "Dynex" is the manufacturer, but the RocketFish website claims that Best Buy, who is the distributor of this product, is also the manufacturer.

Here is the lsusb output with the RocketFish camera plugged in.

Since my installation is pretty fresh, I don't have any other kernel installed to play with.

Hmm, that usb-id does not use any special driver, so likely it is a UVC camera. Do you know with which kernel version the camera was working in F-16?

The best thing to do would be to install an F-16 kernel, download it here:
http://koji.fedoraproject.org/koji/packageinfo?packageID=8

And then install it using:
rpm -ivh kernel-.....rpm

And reboot into that kernel. Then once you know what is the last working and the first non-working kernel,
send a mail explaining your problem to the uvcvideo driver mailing list: linux-uvc-devel.de

I really don't know what kernel I was using when the camera was working. It's funny how, for most people, when things are working fine we don't document, but when things go wrong we wish we did.

I briefly glanced through the list of kernels on that page you sent and didn't see any PAE kernels. I'll keep looking.

The PAE builds are part of the regular builds. For starters I would try a 3.2.x build for F-16 with your F-17 system, ie: http://koji.fedoraproject.org/koji/buildinfo?buildID=307526
