<EM>&gt; Hello
</EM><BR>
<EM>&gt; I have a Microtek ScanMaker II scanner that I've been using successfuly under SuSE Linux 6.3 with the shipped sane.
</EM><BR>
<EM>&gt; I wanted to make a 'scanning server' with an old Sun SPARCStation IPC that I have and that is running NetBSD 1.3, so I downloded the latest sane-backends, compiled and installed (actually the ports collection did that for me).
</EM><BR>
<EM>&gt; When I type &quot;scanimage&quot; the scanner (which is a 3 pass scanner) gives one pass and returns, and when it reaches the initial position, I get an error &quot;scanimage: sane_start: Invalid argument&quot;
</EM><BR>
<EM>&gt; I also set up saned in that machine to be able to scan through the network. When I set up my SuSE's sane to search that host for scanners, everytme I ran sane (for instance sane --list-devices) produced a segmentation fault (after the Sun machine reported a connection from the other host). I decided to upgrade to the latest sane veion, so I uninstalled the RPM sane that came with my SuSE, downloaded, compiled and installed the latest sane-backends (which should be the same version the Sun machine has, since I installed it there only yesterday) and configured net.conf again. Now everytime I type scanimage I get no devices found. (or no scanners were identified...)
</EM><BR>
<EM>&gt; Um... Help?
</EM><BR>
<EM>&gt; The Sun does't have a mouse, so I can't try any UI other than scanimage, but I don't think it's scanimage's fault anyway.
</EM><BR>
<P>As I remember (long time ago that I used a Scanmaker II, so I can of
<BR>
course be wrong with this guess), the scanner is quite slow, especially
<BR>
with color scans. Perhaps you are getting a timeout for the first
<BR>
command needed for thew second pass. The parts of sanei_scsi.for BSD
<BR>
seems to use a timeout value for SCSI command of 1 minute, while Linux
<BR>
uses 10 minutes. Line 2294 of sanei_scsi.c (Sane 1.0.4, for USE ==
<BR>
BSD_INTERFAC) reads:
<BR>
<P>&nbsp;&nbsp;hdr.timeout = 60000; /* 1 minute timeout */
<BR>
<P><P>and line 2386 (for USE == FREEBSD_CAM_INTERFACE):
<BR>
<P>&nbsp;&nbsp;&nbsp;cam_fill_csio(&amp;ccb-&gt;csio,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/* retries */ 1,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/* cbfncp */ NULL,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/* flags */ ccb_flags,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/* tag_action */ MSG_SIMPLE_Q_TAG,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/* data_ptr */ (u_int8_t *)data_buf,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/* dxfer_len */ data_len,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/* sense_len */ SSD_FULL_SIZE,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/* cdb_len */ cmd_size,
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;/* timeout */ 60 * 1000);
<BR>
<P>So, if the Scanmaker II needs more than one minute for a command
<BR>
(perhaps the one to change the light filter), you will get an error
<BR>
under BSD (and also with many other operating systems supported by Sane
<BR>
that use too a timeout of 1 minute).
