[vox-tech] ASUS webcam

[Richard Harke]

To follow up--   My wife loaned me her external web cam. But I found there
doesn't seem to be any way to tell the application which camera to use. In
the process of testing I found that the image in google talk was right side
up using the built-in camera (with the patched driver). I hadn't tried it
because the image was still upside down in cheese. So, while I am still
puzzled, the main problem is solved.
