[Bug 39257] External Firewire DVD-RW not working.

[Thomas McMahon]

Public bug reported:

I have an external DVD burner that I want to connect to my iMac DV via
Firewire. I know that the drive works under Ubuntu because when I plug
it into the USB (1.0) port it works. However it won't work with
Firewire. I'm running Ubuntu Dapper Drake with Kernel 2.6.15-20-powerpc
on an iMac DV 400 Mhz. Here is the output of some commands that I hope
help you find out what's wrong.

This is the output of dmesg before I plug the drive in.

This is the dmesg output after I plug the drive in.

This is the my fstab file.

If there are any other files/commands you want me to do for you then
just say.

Thanks,
