That is actually a dying issue (aside from the whole /dev/sg debate). Users select the CD burner by vendor/device name from the pull down menu in real world computing. The underlying question is how the GUI application does the scan and how it figures out what burner ties to what cd-rom device in the file manager. SG_IO is wonderful here and has solved the latter part nicely. sysfs has solved the former part. Alan
