Pat,

My review of SPC-4 r08 indicates that your comment is
almost right.

CDB byte 2 does contain a 3-bit field in the low-order
bits and that makes your proposed change from 03h to 07h
correct ... as far as it goes.

However, SPC-4 r08 adds the command timeouts reporting
option to the REPORT SUPPORTED OPERATION CODES command.
This new feature defines bit 7 of byte 2 as the RCTD
(Return Command Timeouts Descriptor) bit. When this
change is added to the issue which you have reported
the cited byte needs to change from 03h to 87h.

Unless I hear objections, I will made this change
in SPC-4 r09.

All the best,

.Ralph

Spc4r08.pdf at p.231 discusses "REPORT SUPPORTED OPERATION CODES".  It has an example CDB usage map that labeled as "the" CDB usage map of "REPORT SUPPORTED OPERATION CODES".

A3h, 0Ch, 03h, FFh, FFh, FFh, FFh, FFh, FFh, FFh, 00h, 07h is the example.

A3h, 0Ch, 07h, FFh, FFh, FFh, FFh, FFh, FFh, FFh, 00h, 07h is what I expected at first glance, since the REPORTING OPTION codes go in the three lsb's of byte 2 of the Cdb, and my mask 07h rather than the Pdf's 03h in byte 2 would be a mask of three lsb's rather than two lsb's.

Is 07h rather than 03h in byte 2 yes obviously what we meant to type, or have I misunderstood, or is something interesting happening here?

Curiously yours,
