<P>Could you please use

<P>SANE_DEBUG_MUSTEK=5 xscanimage 2&gt;debug.log)
<BR>
<P>(or whatever frontend you use), scan a small image and send the
<BR>
resulting debug.log to me (if the image is all black I don't need the

image itsself)?
<BR>
<P>Does this happen in any mode (Color, grayscale, lineart)? Does it help
<BR>
to enable &quot;use custom gamma correction&quot; in the frontend?
<BR>
<P><EM>&gt; i use the last version of SANE (103), which i
</EM><BR>
<EM>&gt; compiled on my linux i386 sytem (SUSE 6.3).

<EM>&gt; my scanner is connected to a adaptec 2940 PCI
</EM><BR>
<EM>&gt; SCSI card.
</EM><BR>
<P>Which kernel version are you using? I had some problems with Linux
<BR>
kernel 2.2.15 and below and this SCSI adapter but the symptoms were
<BR>
different. 2.2.17 works. You may try to limit the SCSI buffer to 32 KB
<BR>
(&quot;options buffersize 32&quot; in mustek.conf after the device you use) but
<BR>
I don't think this will help in your case.
