You could try rebuilding the backends with the following command:
emerge -av1 =media-gfx/sane-backends-9999
That will install git commit 6b7052c4, which should get you pretty close
to the same version of the backend that you originally reported working
on Ubuntu, which was version 1.0.28+git20190831-xenial0 from the PPA.
Also, in your original email you reported setting the timeouts as per
> $ grep '^[^#]+$' *.conf
In your output below it's showing a timeout of 100, but I presume you
intended to override that to 5000. You might want to double check that
your config changes are still in place.

No probs ;) I'm hoping that from the overlay we can get better exposure
to testing and get new releases updated in gentoo earlier.
