I too can confirm this problem with Dapper. I have a usb2.0/firewire external hard disk drive and a 4th Gen iPod with both usb2.0 and firewire cables.
Both devices work perfectly using the usb2.0 cable. When hot-plugged, the hard disk automounts and opens the file browser automatically. The iPod automounts and loads up Rhythmbox. Also if I plug them in and then boot up ubuntu they are detected properly. If I hot-plug either device using the firewire cables they are not detected. When I plug the Hard Disk Drive in and boot up ubuntu I get much the same errors as the first poster and it is not detected. If I plug in the iPod and boot up it is much the same, apart from the fact that it does show up in Places/Computer as 'Apple iPod Music Player' When I try to open it I get the following error, Unable to mount the volume. There is probobly no media in the device. mount: /dev/sda is not a valid block device mount: /dev/sda is not a valid block device error: could not excecute pmount When I try to eject / unmount it I get this error, Unable to eject media eject: unable to open '/dev/sda': No such device or address. The problem is not the Firewire card as both devices work as they should in Breezy (other than the well documented iPod unmounting problem). Finally, and I'm not sure how relevant this is, I have tried both devices with the latest version of Mepis (based on ubuntu) and have had no joy in getting either of them detected. -- Firewire connection not being correctly mounted in 6.06 https://launchpad.net/bugs/53746 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
