Olaf, yes, I did. I just checked the Synaptic Package Manager and
confirmed that I have loaded the iscan-plugin-gt-f600 package, version
1.0.0-2. The X scanning apps behave as previoulsy reported.
It sounds like the scanner is returning a value(s) not expected by the
software.<br>
<br>
BTW, I think a reboot may have triggered something. First of all,
the Segmentation Fault I reported in one of my previous posts now seems
to appear only if I run with sudo. If I execute
'SANE_DEBUG_EPKOWA=255 scanimage -d epkowa:libusb:004:003 >
~/test.pnm' I get the following output...back to the "read more data"
warning.<br>
