I have just got a Nikon Coolscan II (the internal model LS-20i),<br>
and have been trying to get it to work under sane-0.74.<br>
<p>
The preview window works just fine, bringing up a good image from the<br>
slide. However, the "scan" button not only fails to work, but it<br>
completely locks up the computer, to the extent that powering<br>
everything down is the only option.<br>
<p>
I wonder if this might be a problem with the SCSI card? I am using<br>
the Adaptec 1505AI which was supplied with the scanner. At one point, <br>
I had the card set to permit SCSI device-disconnect/reconnect, and at<br>
that time 'xscanimage' locked up immediately I pressed the 'scan'<br>
button. Now however, I have disabled that option on the card,<br>
and pressing the 'scan' button causes the scanner to take in the<br>
slide, make a funny noise, then spit it out again before locking<br>
the computer up.<br>
<p>
Is there some other card option which is needed by the coolscan<br>
backend, but which I might have disabled, or vice versa? For instance,<br>
there appears to be something called 'sync' which I have disabled.<br>
Should I try enabling it?<br>
<p>
Alternatively, if it is a software problem, how does the low-level SCSI<br>
format of the 'scan' command differ from the 'preview' command, since<br>
the latter works but the former doesn't?<br>
<p>
Regards,<br>
Malcolm<br>
<p>
P.S. My system is Linux 2.0.34, using the aha152x SCSI driver as a<br>
module.<br>
P.P.S. If someone can supply the Nikon programming specs, I would be<br>
happy to delve into this question myself.<br>
