Hi Snapscan experts everywhere,
<BR>
<P>I have just updated Sane for the first time since I updated the Snapscan
<BR>
driver last spring to correctly merge the colours, and to work with my
<BR>
Acer 610+. I have updated to Sane 1.0.4, xsane 0.72, and the
<BR>
snapscan-11282000 code from Sourgeforge. Now I get something odd.
<BR>
<P>I am using RedHat 6.2, with all the relevant update RPMs, plus a stock
<BR>
Linux 2.2.18 kernel I needed to get USB working (not for the scanner,
<BR>
though). My scanner is an Acer 610+ (SCSI) connected to its own private
<BR>
Adaptec 2840 card (aic7xxx.o driver, as a module).
<BR>
<P>The scanner scans, but sometimes stops for maybe 10-15 seconds of total
<BR>
silence, then continues for a bit, then stops for another 10-15 seconds,
<BR>
then continues. The final result eventually looks correct.
<BR>
<P>The machine is fast (700MHz Athlon), the SCSI card is capable of high
<BR>
performance, and there is nothing else happening on the machine during
<BR>
these scans.
<BR>
<P>When I used Sane 1.0.1 with the snapscan driver I modified, and xsane
<BR>
0.59 I never saw this happen.
<BR>
<P>Can anyone shed any light on this?
<BR>
<P>Regards,
<BR>
Steve
<BR>
