It is fully supported since 2017-04-26.  sane-backends-1.0.27 was
released 2017-05-22, so based on

I'd say you have to upgrade your libsane package as you appear to have
1.0.25+git20150528-1ubuntu2.16.04.1 installed 'now'.

The output you show is a bit misleading as it shows all the packages
that are *available*, not just the ones that are installed.  Check with

  apt-cache policy libsane

to see what version is installed and upgrade to a 1.0.27 version.

BTW, you don't need libsane-dev, just libsane.

Hope this helps,
