Hello,<br>
<p>
(first, I apologize for the length of the post and my<br>
 poor english)<br>
<p>
I'm trying to use a Microtek 600GS on a SPARCstation 1+<br>
 running Solaris 7. The installed 'Generic SCSI' is the<br>
 SCG driver by Klaus Schilling (aka SOLARIS_INTERFACE).<br>
<p>
At first, the scanner was not recognized, it reports<br>
 "MII SC25 ScanMaker 600GS V4.6", and the microtek backend<br>
 only check for "SC {21,23,31}". Only find-scanner would<br>
 see it (trivial patch at the end of message, now it is<br>
 seen as a "600ZS").<br>
<p>
Now, it is seen, but doesn't work.<br>
<p>
First, there's a mis-feature inside the Solaris-SCG backend :<br>
 there's a seg-fault roaming line 2658 of<br>
 "sane-1.0.1/sanei/sanei_scsi.c" when DEBUG_LEVEL &gt;= 3; the<br>
 DEBUG line try to printf() "*dst_size", which is sometimes<br>
 explicitly NULL.<br>
<p>
Second, line 2688 of this file is :<br>
2688:      if (*(u_char *) &amp; scmd.sense &amp;&amp; handler)<br>
When I try to "preview", "*(u_char *) &amp; scmd.sense" is 0,<br>
 so the backend throw to an I/O error.<br>
I've tried removing the check (maybe it's stupid ?), the result<br>
 is that the scanner start doing _something_ : the light move<br>
 from one side to the other, go back, then the software hang.<br>
After a delay, I got SCSI error on the console :<br>
<p>
####<br>

####<br>
<p>
Also,<br>
"[sanei_scsi] sanei_scsi_cmd 8: timeout"<br>
"[sanei_scsi] sanei_scsi_cmd 1b: timeout"<br>
are send to stderr by xscanimage. Plus, an alert box with<br>
 "Error during read : Error during device I/O" shows up.<br>
<p>
I still can quit xscanimage, but the scanner won't talk to<br>
 anybody until everything is power cycled, it seems.<br>
<p>
If I "scan" instead of "preview", the result is almost the<br>
 same, that is, the back-and-forth move is replaced by<br>
 a window and the scanner seems to scan, but fails at the<br>
 end with the same SCSI error.<br>
Note : when the light reached the end of the scanner, the<br>
 progress bar is only at around 5-10% of the total.<br>

Here is the scanner inquiry:<br>
