This device appears to only have four ports. Can you switch between ECM
and RNDIS using some AT command?

Does the device use the same PID in RNDIS mode?

Or is RNDIS perhaps not at all supported?

I've applied the patch after dropping RNDIS above and with the minor
changes below, but please clarify this so I can update the commit
message if needed (e.g. if this should have said "ECM/RNDIS" or
similar).

Next time, please keep the PID defines sorted by value.

And the device-id entries sorted alphabetically.

Thanks for the tips Johan, I'll do better next time.
Yes, the device supports RNDIS mode with the same PID and you can switch with a AT command, so I think it should be ECM/RNDIS.

usb-devices output in RNDIS mode:

Thanks for clarifying. I'll update the commit message accordingly.
