This has always been an issue for IEEE 1394 AV/C DV devices on Ubuntu
since Edgy at least. The issue is that the user must have read/write
permissions to /dev/raw1394 and the defaults have been changed to
accommodate disk devices:
$ ls -l /dev/raw1394
crw-rw---- 1 root disk 171, 0 2007-09-06 05:23 /dev/raw1394
So the user needs to be added to the 'disk' group:
$ sudo usermod -aG disk ${USER}
and then log-out/log-in for the group change to take effect.
/etc/udev/rules.d/40-permissions.rules has the following:
# IEEE1394 (firewire) devices
# Please note that raw1394 gives unrestricted, raw access to every single
# device on the bus and those devices may do anything as root on your system.
# Yes, I know it also happens to be the only way to rewind your video camera,
# but it's not going to be group "video", okay?
KERNEL=="raw1394", GROUP="disk"
KERNEL=="dv1394*", GROUP="video"
KERNEL=="video1394*", GROUP="video"
Confirmed with Gutsy Tribe-5 64-bit.
