For a quick check that it's working run jarckd as root:

$ sudo jackd -d firewire

Setting permissions on the /dev/fw* files will only work temporarily.
When you unplug and replug your device the file(s) will be re-created
with the default (root) permissions. You need to create a udev rule.
Here is the file that I created:

$ cat /etc/udev/rules.d/60-firewire.rules 
KERNEL=="fw*", GROUP="audio", MODE="0664"

This will cause the fw* files to be created with audio as group, and the
right permissions. Obviously you also need your user to be a member of
audio.
