saa7115: black image

I have an embedded platform with a Hauppage USB Live video capture dongle. I recently upgraded to 3.0.12 and now I get no image at all - a nice pure black is all I get.

I am sure that the dongle is getting a signal. This same hardware used to work with an older 2.6 kernel.

Partial lsmod:

root@anchor:/etc# lsmod

and this shows up every time the device is opened:

I can't help but think I am missing a module, or firmware, or something.... But with no messages to go on it's a bit of a mystery.

And yes, I've tried different inputs on the dongle; 0 is the composite in and 1 is the s-video. I'm using input 0.

OK, I get the bonehead of the weekend award. I'm getting a black image because.... drum roll please.... the power to the camera was off. Sorry to pollute the list with my boneheaded-ness. :-)
