"make load" loads the parallel port kernel scanner module. Don't do
that. You don't have a parallel port scanner.

 See man sane-plustek. Edit plustek.conf if necessary.

Don't put everything in one line! "rmmod scanner" is for unloading the
scanner module, "modprobe scanner ..." is for loading it again with
options set. And don't put spaces aftert the "=". Anyway, as
sane-find-scanner has detected your scanner there is no need for this
command.

Show us what you did. Also show us the output of

SANE_DEBUG_PLUSTEK=255 scanimage -L

It's supported by the Plustek backend, so you must make sure, that
"plustek" is in dll.conf.
