<EM>&gt; &gt; The scanner is a Microtek Scanmaker V300 parallel port scanner. I'm

<EM>&gt; &gt; running Linux Mandrake 2.2.9-19mdk. It was quite a struggle, but I
</EM><BR>
<EM>&gt; &gt; managed to install the ppscsi kernel patches. I can load ppscsi, sg,
</EM><BR>
<EM>&gt; &gt; and onscsi with insmod without a problem. When I run 'scanimage -d
</EM><BR>
<EM>&gt; &gt; microtek2:/dev/sga', however, I get &quot;Error during device I/O.&quot; I looked
</EM><BR>
<EM>&gt; &gt; through the san-devel mailing list archives and found that someone else
</EM><BR>
<EM>&gt; &gt; had a similar problem, but I never saw an answer ... just advice to set
</EM><BR>
<EM>&gt; &gt; SANE_DEBUG_MICROTEK2=30 and publish the results. I did that.
</EM><BR>
<EM>&gt; It happens to me too that i get i/o errors.
</EM><BR>
<EM>&gt; Strange thing is it happens even more with Sane 1.0.2 then with Sane 1.0.1.
</EM><BR>
<EM>&gt; The firmware could make a difference, you should at least use Firmware 1.60 is
</EM><BR>
<EM>&gt; what i've heard. There was just a mailing about that this week. My scanner has
</EM><BR>
<EM>&gt; firmware 2.1 but it still happens, but well, maybe less then with older
</EM><BR>
<EM>&gt; versions of the firmware.
</EM><BR>
<EM>&gt; i tried my scanner with the cheap adaptec isa card, and it didn't seem to make
</EM><BR>
<EM>&gt; much difference, so a cheap scsi card might not be the solution. I don't know
</EM><BR>
<EM>&gt; if an expensive scsi card would make a difference.
</EM><BR>
<P>I have a Genius ColorPage EP, which is actually a Microtek V300 parallel
<BR>
port scanner packed by Genius. I checked the FCC ID and found that it was
<BR>
made by Microtek, and the both scanners have the same specifications.
<BR>
<P>I installed ppscsi, changed sane source code so that it would detect my
<BR>
scanner as a V300, but I still couldn't get it to work. I can insmod ppscsi,
<BR>
onscsi, and the scanner is correctly detected, but it locks when I try to
<BR>
scan anything with scanimage.
<BR>
<P>I think maybe the problem is with the firmware, but this is wild guess. I'm
<BR>
a little clueless here: what is a firmware? :) Can I download a new version
<BR>
from somewhere and put it in my scanner? How do I do this? Or should I set
<BR>
SANE_DEBUG_MICROTEK2=30 and publish the results?
<BR>
<P>One other question: you said you tried your scanner with a SCSI card. My
<BR>
scanner is a parallel port model, but it has a third port (one for printer,
<BR>
one for the computer, and the third) undocumented. Is is a SCSI port? Yes, I
<BR>
have never seen a SCSI port before. :)
<BR>
<P>I would appreciate any help, it's been 2 years since I'm trying to make this
<BR>
scanner work with Linux.
<BR>
<P>TIA,
<BR>
