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.
