I usually do sudo chown -R username:username /dev/*1394* where username is
the username of the user you are trying to run code from. This lets me use
my Point Grey firewire cameras. I found that I usually need permissions on
more than just the /dev/raw1394 device, hence the recursive chown.

Hope that helps.
