uvcvideo failed at some resolution

[Rodrigo Linfati]

The webcam in dell 1420 dont work correctly, some program dont work ( cheese not work, ekiga work, mplayer, vlc, gst-launcher need a specific resolution of 353x288 config to work OK )

the problem is the resolution, the webcam work only at 352x288 and some other... but at 800x600, 1600x1200, etc, etc. dont work.

A Workarround:
Compile the lasted version from http://linuxtv.org/hg/~pinchartl/uvcvideo/ and copy uvcvideo.ko videodev.ko v4l1-compat.ko to /lib/modules/2.6.27-9-generic/misc/ and apply depmod -a, rmmod, depmod. Now the module say:

[ 8361.587038] uvcvideo: Found UVC 1.00 device Laptop Integrated Webcam (05a9:2640)
[ 8361.587420] uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround.

And the webcam work OK on all program!
