Hi,

<EM>&gt; After quite a few helpfull suggestions and a session with Lawrence
</EM><BR>
<EM>&gt; (thanks!) I have the 1212U_2 working. First I thought there was somewhere a
</EM><BR>
<EM>&gt; problem in the programs (in a way there still is...).
</EM><BR>
<EM>&gt; The symptoms: works under xscanimage/xsane, in grayscale and line art but
</EM><BR>
<EM>&gt;_NOT_ in color. In color mode, color 'banding' appears horizontally,
</EM><BR>
<EM>&gt; evidently caused by something else... Why? Because scanimage (without the
</EM><BR>
<EM>&gt; X), does work correctly, even in an Xterm.
</EM><BR>
<EM>&gt; So, the problem seems to be in the GUI part of both xsane and xscanimage.

<P>I'm trying out scanning under Linux for only a week or so, after I had
<BR>
installed the new kernel 2.2.18 (with usb support implemented,
<BR>
no backport needed).
<BR>
With much help that I got by browsing this list I ended up in a state
<BR>
quite similar to John's:
<BR>
<P>- scanimage works fine with my Agfa SnapScan 1212
<BR>
- xscanimage/xsane give a preview looking somewhat shred when in color mode
<BR>
- the scanning process (color) with xscanimage does't even finish, the
<BR>
&quot;progress indicator&quot; seems to be frozen
<BR>
- xsane does something like scanning with bad results similar to the preview
<BR>
- xscanimage/xsane work fine in greyscale.
<BR>
<P>It may be interesting that the scanning module of STAROFFICE 5.2 recognizes
<BR>
/dev/usbscanner and yields good scans in color.
<BR>
<P>My system setup:
<BR>
- Caldera eDesktop 2.4 with Kernel 2.2.18 recompiled
<BR>
- KDE 2.0.1
<BR>
- Agfa Snapscan 1212U-2 with firmware of Jul 12 1999 uploaded by agfafirm
<BR>
- sane 1.0.4
<BR>
- latest snapscan backend from the site snapscan.sourceforge.net (with
<BR>
snapscan.h slightly changed in line 104 to make the device string
<BR>
&quot;AGFA SNAPSCAN 1212U_2&quot; recognized).
<BR>
Any help would be appreciated
<BR>
