+# The targ driver provides target mode support as a Processor type device.
+# It exists to give the minimal context necessary to respond to Inquiry
+# commands. There is a sample user application that shows how the rest
+# of the command support might be done in /usr/share/examples/scsi_target.

+# The targbh driver provides target mode support and exists to respond
+# to incoming commands that do not otherwise have a logical unit assigned

 # The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
