To get Ekiga on 7.10 to use UVC, you need to select V4L2, not V4L. V4L 
as far as I know doesn't understand UVC...

Ekiga will use V4L by default, so you have to select the V4L2 interface 
for video and then when the next screen appears to select the actual 
device, you will have the UVC camera listed.
