udev, ide-scsi, and 2.6

I recently moved from devfs to udev on kernel 2.6.4 which works almost perfectly. The only problem now is that my cdrw (via SCSI emulation) doesn't seem to work anymore (devices are missing from /dev).

Anyone have any suggestions? I didn't see anything obvious in /etc/udev/udev.rules that I might have missed.

I realize that ATAPI is recommened for kernel 2-6 but I can't get it configured correctly for ANY of my burning front ends (xcdroast, gtoaster, simplecdr-x). Plus it seems like, though it's supported, it's not quite as prevalent as SCSI emulation in terms of front end support.

Any help would be much appreciated.

I don't remember the default kernel name of an ide-scsi device, but let's assume it's sr*. In that case, all you need to do is adding this line in /etc/udev/rules.d/10-local.rules (create it if needed) :

When I used scsi-emulation it was 'sr0'. But have had no problem using ide-cd with udev. Just compiled it into the kernel and added the line to grub/lilo when boot to use it instead of ide-scsi. Gcombust did complain when told it to use /dev/hdc, but still worked and haven't noticed any issues with K3b.

I thoguht that since 2.6 ide-cd was depreciated and ide-scsi was the way to go? I would like to do it the recommended way if possible.

No, exactly the opposite. Linus never liked the scsi emulation.

I see, scsi-emulation = bad?

Most frontend (xcdroast which I use) and others I have heard don't play nice/nicest without it. What would be best here? Boot with ide-cd and wait for the frontends/backends to work well without scsi-emulation or what?
