when i put the mustek-files by andreas bolsch (version 0.3)<br>
into my sane-package (0.73) and compiled it, my scanner<br>
(Mustek scanexpress 6000SP) worked ...<br>
<p>
now i recompiled the package with version 0.4 of the <br>
abovementioned patch, to get around a colour-bug ...<br>
now, when i boot, the scanner is still recognized properly<br>
by the kernel, however: when entering ...<br>
<p>
prompt&gt; scanimage -d /dev/sg0<br>
<p>
i get the message <br>
<p>
prompt&gt; open of device /dev/sg0 failed: invalid argument<br>
<p>
(the same with xscanimage)<br>
<p>
when i type ...<br>
<p>
prompt&gt; ls -l /dev/sg0<br>
crw-rw----   1 root users  21, 0 Jul 26 21:45 /dev/sg0<br>
<p>
so the device is there ...<br>
<p>
the scanner did work allready (with version 0.3 of the mustek-patch)<br>
and since then the only thing i did to my system, was to recompile<br>
the sane-package with the new mustek-files ...<br>
on the other hand i dont think, that these files are the reason<br>
for the problem, since i allready received the same<br>
error-message with the old 0.3-version of the<br>
mustek-backend ... and then somehow i could make<br>
the scanner functioning properly in the end<br>
the problem is: i cant remember how i did it!<br>
(actually: i never knew, but it worked in the end)<br>
<p>
any suggestions ??<br>
thanx!<br>
<p>
