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. <<<snip>>> [epkowa] sane_open(libusb:004:003) [epkowa] init_options() [epkowa] open_scanner() [epkowa] setvalue(option = 39, value = 0xbfd68824) [epkowa] set = 0.000000 [epkowa] setvalue(option = 40, value = 0xbfd68824) [epkowa] set = 0.000000 [epkowa] sane_start() [epkowa] open_scanner() [epkowa] scanner is already open: fd = 0 [epkowa] reset() [epkowa] send buf, size = 2 [epkowa] buf[0] 1b .
