That version of the driver probably does not support Format7 modes.
Try one of the mono8 modes, instead.

The newest camera1394 (for Diamondback) does handle Format7 (though
not perfectly), but it has no special code for BumbleBee. If you need
that someone will have to port something similar to BumbleBee, which

For E-turtle, we should develop a "standard" BumbleBee driver, if
someone is willing to maintain it. There seem to be enough users to
