Kino reports the device it is trying to open. The quick and dirty answer is to change the group ownership on that device file (/dev/whatever) to your own group. The module/device has "1394" in the name, I think.
The nicer, tidier, more extensible, and arguably *right* way to do it would be to set up a firewire users group, put yourself in it, and give the device that group ownership. You will then need to set that group
ownership on each boot, of course. There is a mechanism for that which I can't remember off the top of my head, but it's used to do things like provide access to serial ports to the dialout users group.
