Explore and experiment with /etc/sane.d/plustek.conf

It looks like your USB system is finding the device fine, and the
sane-find-scanner command is as well, but the sane system itself is not
configured to find it with normal sane commands.  If it doesn't work
automatically, you might try manually configuring it with the output you
identifed above.
