Well, this needs to stop eventually, and...

...node_count...selfid_count need to become 2 (one for the card, one for 
the camera).  And there need to appear two more subdirectories in 
/sys/bus/ieee1394/devices/ (one for the camera, and another one for the 
protocol unit which the camera implements).

If all this at the driver level never gets sorted out, dvgrab doesn't 
have a chance either.

The other sysfs values are OK.

As another quick test, you could unload the controller driver (modprobe 
-r ohci1394), plug in/ switch on the camera, then reload the controller 
driver (modprobe ohci1394).

That's OK.

This is not necessary; but a non-root user who wanted to run dvgrab 
would should be member of teh video group, and there needs to be rw 
access to the device file for the group of course.
