I'm not sure what you expect from the ses driver
in the kernel. If it likes an SES device (and it
doesn't like some of them) then you will get a
small, but useful, set of knobs to twiddle and
read in sysfs. As far as I can see the ses driver does
not create any device nodes (as found in /dev).

Hi,

Eric Youngdale ** - 11/1/93. Version 1.0.
Version 1.81 was ported to sginfo in 1998 and placed in the
sg_utils package. For more than 10 years I have been trying
to discourage people from using it. It contains next to no
modern VPD or mode pages and many of the standard INQUIRY
ddpt is yet another variant of the venerable Unix dd command
line utility. This version adds application side support for
a second offloaded copy mechanism defined by T10 around two
years ago and already on the market under the name ODX.
