Well, that would be overkill, but iterating across, say, /sys/class/scsi_device seems like it would be a good idea.
(I doubt libscg would ever be interested in the stuff in most of the other directories: things like /dev/mem are not SCSI devices and never will be, and /sys/class/scsi_device contains *everything* Linux considers a SCSI device, no matter what transport it is on, SATA and all. However, I don't know if it handles IDE devices that you can SG_IO to because I don't have any such here. Anyone know?)
