Comment 2 for bug 378496

Confirming that two entries appear with ZTE MF637, using both nm-applet and plasma-widget-network-manager.
nm-tool shows:
===========
- Device: ttyUSB1 --------------------------------------------------------------
  Type: Mobile Broadband (GSM)
  Driver: option
  State: disconnected
  Default: no

  Capabilities:

- Device: ttyUSB2 [Orange] ----------------------------------------------------
  Type: Mobile Broadband (GSM)
  Driver: option
  State: connected
  Default: yes

  Capabilities:
===========

ttyUSB1 should not be there. When NM detects the modem, it says:
===
<info> (ttyUSB0): ignoring due to lack of mobile broadband capabilties
===

It should also ignore ttyUSB1, because only ttyUSB2 (the last one) has broadband capabilities.
