Thanks Louis for the hints.

I did not want to have much effort, so I did not install the 
USB-sources, although it might be dangerous. I expect to have the 
expected support in one of the next official Ubuntu updates. So I did it 
quick and dirty. Later I found a German description, for what to do, but 
it seems slightly more complicated.
https://wiki.ubuntuusers.de/SANE/Kompilieren/

So what I did after the download and extract (which I had done before to 
check the sources for string "MG5700 series").


cd sane-backends-e3ed043

./configure
make

I read PROBLEMS, because that is what they tell you during compilation.

As root:
make install

"Remove" current sane libs:

(Which are not in /usr/lib, as described in the README file. In the file 
INSTALL there is more accurate information. The dynamic solution in the 
INSTALL.linux was too complicated for me.)

mkdir /usr/lib/i386-linux-gnu/xxxsane
cd /usr/lib/i386-linux-gnu
mv sane xxxsane
mv libsane.so.1.0.25 xxxsane
mv libsane.so.1 xxxsane

As normal user:
Add installation dir to library search path:
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib

It worked.
So I added this last line to my .bashrc

Many thanks to the developers of the sane software.

Best Regards,
  Horst.
