[sane-devel] Re: HELP! Epson Perfection 4180 Photo

One more thing.  I was reading the Avasys FAQ (specifically, the question
"Previewing and Scanning does not work") and there was a workaround for this
particular issue/scanner combination.  It sugggested that I comment the
'net' backend in dll.conf, which I did.  Now, when I run the iscan command
with debug on, I get a different error message:

$ SANE_DEBUG_EPKOWA=255 sudo iscan
[sanei_debug] Setting debug level of epkowa to 255.
[epkowa] sane_init: iscan 2.1.0
<<<snip>>>
[epkowa] sane_get_devices()
[epkowa] sane_open(libusb:004:004)
[epkowa] init_options()
[epkowa] open_scanner()
[epkowa] setvalue(option = 43, value = 0xbf940130)
Segmentation fault
