Name
CHR_DEV_SG — SCSI generic support
Description
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
https://www.sane-project.org.
For CD writer software look at Cdrtools
https://cdrecord.berlios.de/old/private/cdrecord.html,
and for burning a "disk at once," check out CDRDAO
https://cdrdao.sourceforge.net.
Cdparanoia is a high quality digital reader of audio CDs
(https://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.
