Hi,
I think (somebody beats me with a stick if I'm wrong) the two firewire
stacks are currently built in the Debian kernel.
So you could try to unload the current firewire driver, and load the
alternate one, and see how it goes.
To see which modules are available in you kernel :
modprobe -l | grep firewire
To see what is loaded :
lsmod | grep firewire
So if one, or both are loaded, use "modprobe -r module" to unload, and
try to reload one at a time.
You can run
watch "tail /var/log/kern.log"
in a console while plugging the camera to see which driver is loaded
automatically.
Of course some cameras are just not Linux friendly, and then you are
stranded... In such a case you would have to go with an alternate method
to capture the video stream (acquisition card through "s-video" port or
such).
Have fun.
