[intrepid] Driver lies about available resolutions

[Vadim Peretokin]

Binary package hint: cheese

In Ubuntu 8.10 final, Cheese may appear as failing to work for people with the "Bus 003 Device 002: ID 04f2:b018 Chicony Electronics Co., Ltd Video Device" USB webcam. It displays nothing.

In reality, the issue is that it chooses a resolution too high by default. The resolution it should be using is 800x600. One higher than (1280x960) that results in very laggy and color corrupted video, and one above that (1600x1200, the max, and default) makes Cheese display nothing.

Apparently the driver shouldn't be reporting the two higher resolutions.

This is a confirmed issue and the proposed fix works on System76 Serval 3 laptops, as confirmed by System76: http://ubuntuforums.org/showthread.php?p=6105732#post6105732

"Cheese just sets by default the best available resolution.
If your webcam driver advertises a resolution it doesn't actually support I
don't actually see how it could be our fault.
Please report this issue to your driver (uvcvideo?) developers."

The linux update received today fixed this - while 800x600 remains the optimal resolution, higher ones work fine.
