How to get access to raw1394 as unprivileged user?
Answer added in October 2009 Many recent Linux distributions allow only the root user to access /dev/raw1394, either deliberately due to an incomplete understanding of FireWire security implications (Ubuntu), or because they didn’t notice that some Ubuntu udev rules were merged into mainline udev. In most desktop-oriented installations (if they still run the old ieee1394 driver stack rather than the newer firewire driver stack), it is most desirable to grant unprivileged users access to /dev/raw1394. Otherwise, applications like coriander, dvgrab, ffado, or kino won’t be able to recognize attached cameras or audio interfaces. (Storage devices are unaffected because raw1394 is not used for them.) Steps to fix this: • As root, make sure that the raw1394 driver is loaded into the kernel: modprobe raw1394 • List ownership and permissions of the device file: ls -l /dev/raw1394 • List the groups to which your normal account belongs to. As normal user, run id • If /dev/raw1394 does not belong
