Thank you, that did the trick: It got recognized by the probe!
Now the attach is the problem:

I tried with both with CDCE_FLAG_ZAURUS in there, no differences.
I tried it without CDCE_FLAG_NO_UNION and then I got this:

Is that better? I don't know yet...
At least ue0 gets created, but the link light doesn't go on the modem...
I will take some traces on Monday on a Windows machine to see what needs
to be happening after the attachment of the interface.
