[sane-devel] Fwd: Why will sane-find-scanner detect my scanner, but scanimage -L won't?

[M. Allan Noah]

You need to extract the firmware from the windows driver and put it where sane can reach it. See /etc/sane.d/epjitsu.conf

Everything went smoothly until I got to the point of trying 'scanimage -L'.
