Hi,
The change I made is for cinterion plugin only:

The quectel plugins does not whitelist the 0x1269:

So it's weird it matches the MV31-W modem
I also tried using the mbimcli directly but it does not work as well:

Ok. I think you're the first ones I know of doing that testing :)

Those warnings above show that the current available rules to flag port type hints based on either type or name are failing badly when using the limited built-in udev parser. I've opened this issue to track it: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/410

Wait what, it should not attempt to try with the quectel plugin at all. Can you share what specific changes you did? Did you by any chance modify the quectel plugin to add the cinterion PCI vid as a test?
