It sounds like your normal user does not have read/write access to the relevant ieee1394 devices. I cannot remember which devices they are, but I believe /dev/raw1394 or similar is one of them. There are others for camcorder control and recording, I believe. There are potential security issues with making the firewire bus read/writable by a normal user - any ieee1394 device can be accessed via the bus, so if you had a firewire harddrive for example, a normal user could completely trash it... Personally, I don't care about multi-user secutiry issues on my laptop though, I'm more concerned with the security issues of people walking off with it ;-) Cheers, Jason
