CHR_DEV_SG — SCSI generic support
If you want to use SCSI scanners, synthesizers, or CD-writers, or just about anything having "SCSI" in its name other than hard disks, CD-ROMs, or tapes, say yes here. These won't be supported by the kernel directly, so you need some additional software that knows how to talk to these devices using the SCSI protocol:
For scanners, look at SANE http://www.sane-project.org. For CD writer software look at Cdrtools http://cdrecord.berlios.de/old/private/cdrecord.html, and for burning a "disk at once," check out CDRDAO http://cdrdao.sourceforge.net. Cdparanoia is a high quality digital reader of audio CDs (http://www.xiph.org/paranoia). For other devices, it's possible that you'll have to write the driver software yourself. Please read the file Documentation/scsi/scsi-generic.txt for more information.
