Could you make any progress?

I was targeting to have the vendor-specific plugins provide QMI
support themselves, instead of always falling back to the generic
plugin looking for QMI support. The main reasoning is that the probing
will be quicker if there's a VID-based filter that grabs the plugin
right away, instead of falling back to generic, which among other
things may try the vendor/product string probing, which is slower. Not
sure if this idea is good or bad, but I think it makes sense.

What do you guys think? I believe the Telit plugin has the same
'issue', it doesn't explicitly support QMI and falls back to the
generic plugin for the LN920.

Try the following patch if you can; also ensure you are building
ModemManager with QMI support (which is the default).  Basically, we've
never seen a QMI SimTech device before, and the SimTech plugin is only
built to work with PPP-style devices.  So it may work but just not use
the wwan0 port.  This patch will move your device to the generic QMI
plugin:

SIM7100E

I have a problem with SIM7100E. Though kernel creates wwan0 device, it
is not visible in ModemManager.

If I unload option driver and restart MM, then it sees wwan0 interface
and I can connect and get IP via DHCP.

I've attached MM's debug log.
