If you plug a video camera (ieee1392 Firewire) and launch Kino (for example) your camera won't be detected.
You first need to modprobe the raw1394 module and then chmod the /dev/raw1394 device (according to many howto's...). That's not user-friendly.
The default user should be included in the group of /dev/raw1394 and the system should automatically detect the camera and load the raw1394 module
