I'm semi-offline at the moment, having only occasional gsm edge access... And I see that the post I was thinking of only contains the least interesting part of the equation.  It is focused on the (for me) new and exciting usb comp qmi messages.

I do have more details on my laptop, but I won't have access to that for a few weeks. 

Anyway, here is a start (with a non obvious subject):
lists.freedesktop.org/archives/libqmi-devel/2015-February/001104.html

Using the mbim service mentioned there to send the qmi fcc message Aleksander has documented in libqmi should make this modem work in mbim mode too.

You might have more success than me googling.
