Kino: raw1394 kernel module not loaded or failure to read/write /dev/raw1394!

I am borrowing a video camera this week for a project and I want to be able to edit video. The first program I decided to install was Kino. It seems pretty full featured so far and I am impressed. I wasn't able to pull down video over the 1394 (FireWire) interface (/dev/raw1394) at first though. I got the error message:

WARNING: raw1394 kernel module not loaded or failure to read/write /dev/raw1394!

This was an easy fix. My problem was the latter. I could not read/write from/to the device. To fix that, open up a command line and do this:

sudo chmod a+rw /dev/raw1394

That will change the file permissions to allow all users read and write access. You can verify all users have read/write access now by doing this:

$ ls -l /dev/raw1394
crw-rw-rw- 1 root disk 171, 0 2008-04-12 19:56 /dev/raw1394


(File permissions explained) The third set of rw needs to be there.

That is hopefully all there is to it for you. It would be nice if the file permissions were automatically changed.
