I'm a linux device driver developer. I was looking at UAS
specification document. I have basic question from a driver developer
perspective. Pardon me if this is not the right question that needs to
be asked at this place.
The command sequence diagram for non-data, data-in or data-out has a
different sequence of communication. Does the driver developer need to
determine type of SCSI command and then handle appropriate command
if <read> SCSI command
handle data-in command sequece
if <write> SCSI command
handle data-out command sequece
handle non-data command sequence
The existing BOT protocol does not require to know the type of SCSI
command, it just fills command block wrapper and gets respose in
command status wrapper.
Thanks in Advance.
