<P>
Folks,
<BR>
<P>I am new to this list; I have been having no luck getting my Microtek
<BR>
X6 USB scanner to work, and after some correspondence with Oliver
<BR>
Neukum, we determined that it might be a bug with the SANE code.
<BR>
Oliver recommends that I post this message here; would be grateful for any
<BR>
help you can provide!
<BR>
<P># export SANE_SG_BUFFERSIZE=32768; scanimage -L
<BR>
&nbsp;&nbsp;device `microtek2:/dev/scanner' is a Microtek ScanMaker X6USB flatbed scanner
<BR>
&nbsp;&nbsp;device `microtek2:/dev/sga' is a Microtek ScanMaker X6USB flatbed scanner
<BR>
<P>Running SANE under debug mode reveals a floating point exception. I have
<BR>
attached a full transcript of the debug mode log:
