| D | scsi-generic.rst | 4 Notes on Linux SCSI Generic (sg) driver
11 The SCSI Generic driver (sg) is one of the four "high level" SCSI device
15 Thus sg is used for scanners, CD writers and reading audio CDs digitally
23 Major versions of the sg driver
25 There are three major versions of sg found in the linux kernel (lk):
26 - sg version 1 (original) from 1992 to early 1999 (lk 2.2.5) .
28 - sg version 2 from lk 2.2.6 in the 2.2 series. It is based on
30 - sg version 3 found in the lk 2.4 series (and the lk 2.5 series).
36 The most recent documentation of the sg driver is kept at the Linux
41 This describes the sg version 3 driver found in the lk 2.4 series.
