    Can you provide us with information (ideally on FreeBSD) on the relevant
    Novatel device(s) that do work on FreeBSD, including which versions they
work on.

Good question.  It appears that some older devices do.  I don't have any other
devices nor working devices.  Just from searching on the web I found that an
MiFi7730, from here:
https://forum.netgate.com/topic/143342/unable-to-properly-keep-usb-ethernet-interface-attached-on-verizon-jetpack-7730l/2

I also found the following on the OpenBSD listserv:
http://openbsd-archive.7691.n7.nabble.com/patch-for-Inseego-Novatel-MiFi-8800L-as-urndis0-td361099.html



    Can you also elaborate on:

    - "tethering on newer devices", as to whether that means you have an older
    device that works, or worked in the past?

Just based on reports from the web.  I only have the MiFi 8800/8000 - the
differences are the frequencies for the cell modem tied to the carrier.


    - "enabling tethering is not get picked up", whaty does this specifically
mean
    with regard to steps to reproduce, commands, outputs, errors,system
    configuration to do so, etc (please provide as attachments)

1) Plug in the device via USB.
2) It should be picked up as an rndis device and assigned to ue0 (assuming no
other ue devices).  [even using usbconfig -d ugen1.2 set_config 1 doesn't
result in an RNDIS ethernet interface being created]


    Additionally, the following may be helpful

dmesg at plugin:
