I've emailed Rainer off-list and sorted out his gentoo specific issues 
with this.

 From his original email, his scanner was working with Ubuntu 16.04 and 
sane backends 1.0.28+git20190831 from a PPA.

Rainer can you try now with the sane-backends-9999.ebuild, which will 
install the current git version of the backends. I'm hopeful that having 
something at least as recent as the known working version may work out 
for you.

I guess the erroneous  behaviour referenced below is not a fair 
comparison, unless you know that the 1.0.28 release version also worked 
on ubuntu?
