OK, so that makes it option 4.  Too bad.  Don't have much more to
suggest then.  Except maybe manually configuring the IP address based on
connection data from QMI. That should be qmicli --wds-get-current-settings, I
believe.

If that doesn't help, then we probably need some snooping. Unless
someone else has a clue?

I'm afraid the network snooping isn't going to tell us much more that
you say above.  See https://wiki.wireshark.org/CaptureSetup/USB for
instructions on USB snooping on both Linux and Windows.  It would
definitely be useful to know which mode Windows use this device, and how
Windows configures the address(es).

Hmm, where did that get set?  It's not in the driver AFAIK.
