Public bug reported:

Hi all,

I hope that this bug won't be already opened. I concern the support of
the Firewire. Until, Lucid it was working okay and it was the 'old'
driver i.e dv1394  and raw1394 modules.

They have been replaced by the new driver named JuJu (like you can see
the specification here :
https://ieee1394.wiki.kernel.org/index.php/Juju_Migration) partielly on
Marverick and totally on Natty and following.

But this module doesn't work. I tested it on three computers on three Ubuntu 
11.04 (two Natty and one Kubuntu) all in 64 bits.
Strangely, when I look if the module fireware is loaded, it seems to miss one 
module. Anyway, there are none repertory fw* and following.... 
See what I obtain in console :
olivier@navi:~$ lsmod | grep firewire
firewire_ohci          40370  0 
firewire_core          62646  1 firewire_ohci
crc_itu_t              12707  1 firewire_core

I have too an AV LInux 5.0 (derivated multimedia Debian) on the same computer 
which have too this new driver and I have been surprised that the firewire 
support was working out-of-box. You can see on the above command a different 
result. 
I put you too a part of the output of Dmesg on this multimedia computer, the 
same command on the AV Linux 5.0 and my camcorder is working with Dvgrab.

I hope that this nasty bug will be resolved on Oneric and following.
This new driver is really well done, it is working out-of-box and the
common user have only just to turn on his camecorder.
