Not forgetting peripheral device types 1eh and 1fh
which are well known logical unit and unknown or
no device type respectively.

Reference: the bottom of table 84 in spc4r05a.pdf .

Well known logical units are out there, linux just
doesn't look for them (see the "select report" field
in REPORT LUNS command).
I have been told of special devices yielding pdf 1fh.

BTW I have tried to add these in the past but my patch
wasn't accepted.
