Description of problem:
Version-Release number of selected component (if applicable): 126.96.36.199-117.fc10.x86_64
Steps to Reproduce:
1. The Webcam works
2. Suspend the system
3. Resume it
4. The webcam does not work any more
The webcam is "05ca:183a Ricoh Co., Ltd", I think uvcvideo module usually takes care of that. (There is some module r5u870 which I cannot make it compile on 2.6.27 kernel, which supported this webcam very well)
rmmod and modprobe does not solve the problem.
The 05ca:183a webcam is not UVC compliant, unless loaded with firmware first. If it works at all before suspend you were either warm booting from windows, or are using some not supported software to load the firmware at boot.
If you were warm booting from windows, you are out of luck. If you are using one of the tools, rerun it after resume.
Work is under way upstream to get the firmware loading done automatically by the UVC driver.
