  SCSI Generic Devices
+ 
+ [CI's comment: There is something wrong with the following
+  paragraph. There is no /dev/sg to begin with.
+  Shouldn't the original sentence ought to read
+  "All SCSI generic devices are placed ..."?
+  We can probably simply state that
+  SCSI generic devices appear under the
+  device directory of the form
+ 	/dev/scsi/hostC/busB/targetT/lunU/
+ 
+ 
+ 	Eg. C=1, B=0, T=6, U=2
+ 
+   /dev/scsi/host1/bus0/target6/lun2:
+   sum 0
+   drwxr-xr-x    1 root     root            0 Jan  1  1970 .
+   drwxr-xr-x    1 root     root            0 Jan  1  1970 ..
+   brw-rw----    1 root     cdrom     11,   3 Jan  1  1970 cd
+   crw-------    1 root     root      21,   5 Jan  1  1970 generic
