My fault: net was enabled, therefore I thought, that it is necessary.
According to your proposal I disabled net and access to ET2711 is
possible. So no need to enable net, airscan alone is sufficient.

I thought eSCL is just a synonym for WSD. Wrong or right? This is my
first approach to scanning and I'm not very familiar with the different
scanning protocols.

It works.

Agreed.

The output is:
