[sane-devel] HELP! Epson Perfection 4180 Photo

[brinkleybw at bigfoot.com]

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.

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.
