Matto Marjanovic:
|Short answer: The latest version of the backend (0.7, available from
| the backend webpage "http://www.mir.com/mtek/", and sent upstream for
| inclusion on SANE-0.73) has MODE_SENSE_1 disabled, so that problem
| should disappear for the time being.
Ok.
One other piece of useful info. Here's what the NCR driver says about that
"extraneous data discarded" message that's being printed when the
MODE_SENSE_1 cmd is issued:
** The target wants to tranfer too much data
** or in the wrong direction.
** Remember that in extended error.
(The internal error is XE_EXTRA_DATA.)
|Long answer: MODE_SENSE_1 used to cause problems for folks using Solaris,
| because apparently the Solaris scsi driver insisted that this was some
| command reserved for tape drives. Why and how it is causing problems for
| FreeBSD I don't know, this is a new complaint. I am curious, however,
| to know why (if you feel like poking around even more), and I would very
| much appreciate it if you sent me an INQUIRY dump from the Microtek backend
| so that I can compare firmware revisions/etc between your E6 and mine.
| Is it some scsi driver quirk, or is the scanner complaining? The big Q.
Right, I'm also interested in what's really going on. It's a good excuse
to get in there and dig around anyway. :-)
I've attached the INQUIRY info to this msg. I'm guessing that this isn't
H/W though because a friend of mine running Redhat 4.1 also on an NCR
SC-200 w/ an E6 purchased at the same time as mine has
SANE_MICROTEK_DEBUG=100 output that matches mine exactly (incl. INQUIRY),
up until the point in sane_start() where mode_sense_1() fails.
So I would guess this is likely software/driver behavior differences
somewhere (sani_scsi Linux/BSD differences, Linux/BSD NCR driver
differences, ...).
Since you've worked more with SCSI at a cmd level more than I, I've
attached the last part of the SCSI debug output from the NCR driver when
running "scanimage". There's one fully successful ioctl() there (the one
before the MODE_SENSE_1) as well as the MODE_SENSE_1 ioctl() that fails
right after it. Would appreciate it if you could give it a short 10-sec
glance and see if anything just pops out at you.
I wonder if the E6's MODE_SENSE_1 reply isn't exactly 36 bytes. (?)
(a shot in the dark :-)
Thanks,
Randall
