[sane-devel] Plustek OpticFilm 7600i

[Torfinn Ingolfsen]

FWIW, I dusted off my old Plustek OpticFilm 7600i scanner, and
connected it to a machine running FreeBSD 11.3-stable and SANE:
root at kg-core1# pkg info sane*
sane-backends-1.0.29
sane-frontends-1.0.14_10

output from sane-find-scanner -v -v (I have removed the non-interesting parts)
root at kg-core1# sane-find-scanner -v -v
This is sane-find-scanner from sane-backends 1.0.29

Just in case anyone feels like working on it.
