How to burn to external CD-RW (FireWire, SCSI emulation?)

Hello,

I have a Freecom Portable II external CD burner, connected through an i.Link/Firewire/IEEE1394 cable. It's detected at boot, and both sr_mod and sg are loaded. I get /dev/sr0 and /dev/sg0 and sg1, which I beleive relate to the burner, and I can mount disks in it via /dev/sr0.

However, I can't figure out how to burn to it. I tried cdrecord --scanbus, and got:

I beleive this may have to do with the fact that it's emulating the IEEE1394 device as a SCSI device. cdrecord dev=0,0,0 --checkdrive gives:

cdrecord: Sorry, no CD/DVD-Drive found on this target.

I tried to tell xcdroast to use /dev/sg0 or sg1 or sr0, but it comes backing saying no device is found. How can I burn to this burner?

I haven't had any experience with setting up a Firewire CD-RW, but I have setup a USB2 CD-RW. It was emulated as a scsi device and cdrecord --scanbus found the device just fine. Cdrecord also burned disks flawlessly for me.

optilude,

Which kernel do you have?

I recall that firewire was broken before 2.4.19 or so.

I'm running 2.6.0-test7 with bleeding edge ACPI patch.

It works fine as a CD-ROM (I can mount disks off /dev/sr0); I just can't burn using /dev/sg0. It looks to me like it's being emulated as an Adaptec CD-ROM drive? Not sure... Is there a way I can force cdrecord to try burning to /dev/sg0 even if it disagrees that it's a CD-RW?
