Hi,

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