ModemManager and Iridium 9522b

Mon Apr 16 16:34:02 UTC 2018

Hi Aleksander,

I have a rule in place, but I'm having some trouble with this new build w/
udev that I've implemented.  Getting this undefined symbol error.  Using nm
I see that a number of the symbols in ModemManager are undefined.  Was
there something I missed during build?
