I think, this is the way it should be done. The ModemManager should 
ignore this device completely and the NetworkManager should configure it 
like an LAN-device.

It is useless to try a connection via serial/ppp/modem-mode while the 
device-firmware itself grabs the built in umts/lte-module and acts as an 
router.


I can't remember trouble with usb_modeswitch. I will investigate the 
behavior again later.

Only one hint: There was a bug in kernel 3.13 regarding this device, it 
is already fixed. 3.13 stable and 3.14 are fine again.
