Dear Olaf I discovered this after my post by myself ...

Nevertheless many thanks for your kind advice. And yes you are right: no 
reboot needed.

In the meanwhile we got the following backends working by doing these steps:


brscan, brscan2, brscan3

a) 'sudo ln -sfr /usr/lib64/libbr* /usr/lib/x86_64-linux-gnu'
b) 'sudo ln -sfr /usr/lib64/sane/libsane-brother* 
c) generate '/etc/udev/rules.d/59-udev-local.rules'
# Brother brscan devices
ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="*", MODE="0664", 
GROUP="scanner", ENV{libsane_matched}="yes"

2. Epson Iscan

a) 'sudo ln -sfr /usr/lib/sane/libsane-epkowa* 
b) generate '/etc/udev/rules.d/79-udev-epson.rules'
# chmod device EPSON group
ATTRS{manufacturer}=="EPSON", DRIVERS=="usb", SUBSYSTEMS=="usb", 
ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="*", MODE="0777"

3. Xerox Workcentre 3225

a) 'sudo ln -sfr /usr/lib/sane/libsane-smfp* /usr/lib/x86_64-linux-gnu/sane'
b) 'sudo adduser $USER lp'

Only brscan4 refuses to work for what reason ever (it works only as root 
and only with xsane, no scanimage, no scantopdf ...) currently we try 
discover if any 'special' udev rules are missing and generating them 
might work.

Any help/advice appreciated.

The owner of the brscan4 Scanner asked Brother. They replied: "read the 
faq, or check over internet if there are solutions from the community".

current state can be observed here 

Some people call using 'MODE="0777" for epson dangerous. The rule was 
installed by the epson-printer-utility. With the rule Iscan works, 
without not.

Thanks for your kind interest
