Title: "version" resulting from scsi command "inquiry"
Post by: ehenkes on June 01, 2010, 12:49:44 pm

Jan Axelson refers in his great book "usb mass storage" to the value for "version" resulting from scsi command "inquiry" (4: SPC-2, 5: SPC-3), but most of my devices show up with version: 2 or 0, none with 4 or 5. Perhaps this should be explained.

Reporting the wrong value in the VERSION field is a common mass-storage device problem:

I would guess that most hosts ignore the field or at least consider that the value is the version number and not the code for the version number.
