Description of problem:
I've got a logitech webcam that has been working just fine in the 2.6.11 kernels.  When I use it under 2.6.11 (even as recent as 2.6.11-1.35_FC3) it works just fine:

However under 2.6.12-1.1372_FC3, it's detected but does not work properly:

Version-Release number of selected component (if applicable):
kernel-2.6.12-1.1372_FC3

How reproducible:
Always

Steps to Reproduce:
1. Plug in webcam
2. Run camstream
3. Open the device.  Notice how you have no picture.
  

Actual Results:  No picture data.

Expected Results:  I should have received video data from the webcam.

Additional info:

It's something that changed between kernel-2.6.11-1.35_FC3 and kernel-2.6.12-1.1372_FC3, because it worked in the former and fails in the latter.
