Hi Henning,
<BR>
<EM>&gt;
</EM><BR>
<EM>&gt; &gt; kernel 2.4.3 + kernel 2.2.16:
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; CVS Tree 1.11 + Mustek backendversion 1.0.105 (as delivered with the CVS
</EM><BR>
<EM>&gt; &gt; ) doesn't work for me. The scanner tries to scan beyond the physical
</EM><BR>
<EM>&gt; &gt; scanarea.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; I'm using Linux 2.2.18 at the moment with an Adaptec 2940. My scanner
</EM><BR>
<EM>&gt; doesn't scan beyond the physical scan area at least not in the modes I
</EM><BR>
<EM>&gt; tried. What did you do exactly? A preview scan or a full size scan?
</EM><BR>
<EM>&gt; In which resolution and mode?
</EM><BR>
I tried to get the same error again, but I got different errors. I tried to
<BR>
aquire
<BR>
<EM>&gt;
</EM><BR>
<EM>&gt; I'm asking all these questions because I don't think I have changed
</EM><BR>
<EM>&gt; anything concerning the Pro scanner between 104 and 105. But you never
</EM><BR>
<EM>&gt; know...
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; &gt; To use the TA I had to hardcode the TA_flag in the sources. It seems,
</EM><BR>
<EM>&gt; &gt; that there is no special byte for the TA in the result string. But I may
</EM><BR>
<EM>&gt; &gt; be wrong.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; It's not in the inquiry information like for the other Mustek scanners
</EM><BR>
<EM>&gt; but you can get the information from a &quot;request sense&quot; command. If a
</EM><BR>
<EM>&gt; TA is present, byte 2 of the sense buffer is 0x40, otherweise it's 0.
</EM><BR>
<EM>&gt; I have implemented that in my code but I'm not sure if it works. I
</EM><BR>
<EM>&gt; think I sent you the source some hours ago. If it doesn't work because
</EM><BR>
<EM>&gt; of the other problems maybe you can extract the detection cahnges and
</EM><BR>
<EM>&gt; try them in 104.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; &gt; If I use the 36 bit option it only works if I start xscanimage directly (
</EM><BR>
<EM>&gt; &gt; e.g. from a terminal box). Then the image is put directly into a file.
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; Scanning with 36 bit with xscanimage as a gimp-plugin results in a KDE
</EM><BR>
<EM>&gt; &gt; error message, which says that KDE can't handle the output. ( may be due
</EM><BR>
<EM>&gt; &gt; to my KDE configuration)
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; GIMP can't handle more than 8 bit/color. But you shouldn't get a
</EM><BR>
<EM>&gt; message from KDE but from xsane.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; &gt; kernel 2.2.17 - 2.2.19 :
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; system hangs if I try scanning with the option quality calibration.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; This doesn't happen here. Maybe this one and the &quot;out of scan area&quot;
</EM><BR>
<EM>&gt; problem are related to SCSI driver bugs? Can you test this with a
</EM><BR>
<EM>&gt; different SCSI controller?
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Thanks for the report.
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; Bye,
</EM><BR>
<EM>&gt; Henning
