Hello,
I have an external USB combo CD-RW/DVD R. Despite I have succeeded to mount my CD-Rom, I do not succeed to configure the CD-burner (see below for example what I obtain with the command line "# cdrecord -scanbus").
My linux distribution is a Fedora Core 2.6.5-1.358
The /etc/fstab file contains the line
/dev/scd0 /mnt/cdrom udf,iso9660,noauto,owner,ro 0 0
Edit /etc/fstab to remove the ro parameter should fix the problem.
Also, you can boot with a CD-RW disk in the system might be another solution.
