Could not connect to video device (/dev/video0)

message box with "Error (camorama)" title:
Could not connect to video device (/dev/video0)
Please check connection.

Video camera is a Microsoft LifeCam Cinema
Camera does work with Skype, and though Cheese has many bugs, it does properly detect and show video from this camera.
Oddly, if I change camorama to point to my ATI HDTV Wonder card /dev/video0, it comes up, but displays a black screen.
