The very first comment looks like bug #39257. (Failure of the very first SCSI command, i.e. INQUIRY, device is perhaps based on the Prolific PL3507 USB 2.0 + FireWire 400 chip whose FireWire part is substandard. Aplle iPods are of course not based on PL3507.)
Please provide the full syslog messages or output of dmesg from the moment the device was plugged in to the moment any error messages have settled. -- 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
