Probably so...

I'm not quite sure what all this means, but thanks for looking into it.

Thanks for the detailed instructions.  I'm not sure what I did but NM is
no longer trying to connect when I plug the phone into the usb port.
Now only the usb detection messages appear in the log.  NM is running:

$ /etc/init.d/network-manager status
  NetworkManager.service - Network Manager
   Loaded: loaded (/lib/systemd/system/NetworkManager.service; enabled;
   vendor preset: enabled)
   Active: active (running) since Sat 2017-01-14 15:29:23 EST; 1 day 23h ago
     Docs: man:NetworkManager(8)

           └─675 /usr/sbin/dnsmasq --conf-file --no-hosts --keep-in-foregroun….d

I did kill MM the first time I used minicom, but I've rebooted the
system since and MM is not restarting on its own.

Thanks again.
