Hi. I just ran a few updates and now my camera works. I think I was
having usb problems. (from this, I discovered that it is an incredibly
shitty camera, but that's beside the point). It works just fine in
luvcview and in cheese.
Now here's the ekiga output with -d 4. I see a camera with plugin v4l,
but isn't mine only v4l2? Maybe I'm wrong.
In a dialogue box, it says "Your video driver doesn't support the
requested video format."
Nothing suspicious is in my /var/log/syslog.
Thanks.
