    Yes. I have that set up and it can't find my camera. But it can find 
the mike in the camera. In Ekiga setup audio you can select camera audio 
and MY camera mike works.

    This tells me I think that the camera is plugged in and powered up 
at least to a point the mike works.

    The video works fine in Windows. I don't think that assures it 
should work in Linux. I might need to buy another camera but not sure 
what. Wal Mart has some cheap ones....
