Did you delete the old gtk/gdk/glib libraries before installing the<br>
|
|
new ones? There is an unfortunate bug in the ltconfig file that makes<br>
|
|
this necessary on Linux.<br>

<br>

|

|
|
Jens> stop and go of the head (especially at the "G" in the 3rd<br>
|
|
Jens> row). In color it is even more bad:<br>
|
|
<p>
|
|
Hmmh, I have had one other report of dropped lines in grayscale mode.<br>
|
|
Unfortunately, I can't reproduce the problem, so I can't debug it.<br>
|
|
Can you look into it? Maybe you could play with different buffer<br>
|
|
sizes and see what's happening as the sizes change. The man-pages<br>
|
|
describe a couple of environment variables that may be helpful in<br>
|
|
tracking this down (e.g., set SANE_DEBUG_MUSTEK and<br>
|
|
SANE_DEBUG_SANEI_SANE to 128). If you can, try it with a different<br>
|
|
SCSI controller, too, since it's quite possible the bug is in the<br>
|
|
driver for the Mustek card.<br>
|
|
<p>
|
|
Jens> Does this happen because there's no model string returned by<br>
|
|
Jens> the driver?<br>
|
|
<p>
|
|
No, if you invoke scanimage with SANE_DEBUG_MUSTEK set to 3, you'll<br>
|
|
probably see the correct scanner type (otherwise, scanimage would<br>
|
|
refuse to scan).<br>
