<P>
I'm running Sane 1.0.4 on Linux - Mandrake 7.2 (kernel 2.2.17), with a
<BR>
Tekram DC-390U SCSI adapter (NCR 53c875e chipset).
<BR>
&nbsp;
<BR>
I have a Umax 1200S and an HP C5100A Rev 032. Both are recognised by the
<BR>
kernel, and the Umax works fine.
<BR>
&nbsp;
<BR>
The PhotoSmart, however: trying to scan a slide, everything seems to be
<BR>
working fine EXCEPT: the image I get from xscanimage is just solid
<BR>
black. All other functions of xscanimage work - when I ask for a preview
<BR>
image, the slide is taken in, it whirs appropriately, and for the scan
<BR>
itself it makes all the right noises and then ejects the slide.
<BR>
&nbsp;
<BR>
I tried using scanimage with and without options: same all black image.
<BR>
&nbsp;
<BR>
What's going on? Do I need to calibrate the 5100A? There is a
<BR>
calibration card that came with the scanner but none of the
<BR>
documentation I've found on the HP backend says anything about
<BR>
calibration.
<BR>
&nbsp;
<BR>
I tried scanning a print: very dark, faint blue image could be observed.
<BR>
However scanning a strip of negatives looks much better.
<BR>
&nbsp;
<BR>
There are no errors in /var/log/messages. Here's the SCSI device list:
<BR>
&nbsp;
<BR>
$ cat /proc/scsi/scsi
