</EM><BR>
<EM>&gt; What scanner is connected to your PC? Is it still this Mustek SE12000P?
</EM><BR>
<EM>&gt; In this case, the scanner is just not recognized. the backend just
</EM><BR>
<EM>&gt; supports ASIC-ID 1013 (CCD-Type 0 &amp; 1) and ASIC-ID 1015 (CCD-Type 0, 1&amp;4
</EM><BR>
<EM>&gt; are unstable) scanners. The Mustek SE120000P reports ASIC-ID 1505
</EM><BR>
<EM>&gt; (CCD-Type unknown)...
</EM><BR>
<EM>&gt;
</EM><BR>
<P>I am impressed you remember :-)! Yes, its the SE12000P. But I patched the
<BR>
source to code think that the asic 1505 is the same as the 1015. A few
<BR>
months ago, this worked, that is, the backend tried to do something with my
<BR>
scanner (and failed miserably, of course), but now that doesn't even happen
<BR>
:-(.
<BR>
<P><P><P><EM>&gt; &gt;
</EM><BR>
<EM>&gt; &gt; If I use a different argument to the right of the : I get often a seg
</EM><BR>
<EM>&gt; &gt; fault, eg:
</EM><BR>
<EM>&gt; &gt; scanimage -d musteka4s2:0x278
</EM><BR>
<EM>&gt; &gt;
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; This is a bug... the backend fails to gain IO privileges using ioparm()
</EM><BR>
<EM>&gt; when the device isn't mentioned in the config file. When the backend
</EM><BR>
<EM>&gt; tries to detect the scanner it catches a SIGSEGV...
</EM><BR>
<EM>&gt;
</EM><BR>
&nbsp;Thanks.
<BR>
<P>I'll double check my 'patches' again, to make sure I didn't left anything
<BR>
out. I've started to work with the code from
<BR>
Donnchadh Ó Donnabháin &lt;<A HREF="mailto:d_odonnabhain@vistech.ie?Subject=Re:%20musteka4s2:%20problems&In-Reply-To=&lt;0FVK0075RFHUX4@smtp.netc.pt&gt;">d_odonnabhain@vistech.ie</A>&gt;
<BR>
and I'd like to be able to start mixing both codes...
