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