Title:
  Android tethering does not work when network manager is running

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  After lost many hours trying to discover why the USB Tethering of my
  LG E615f and my friend's LG E470 android phones, I just realised:

  (with cable unplugged)
  alex@ubuntu_asus:~$ sudo start network-manager 
  network-manager start/running, process 3843
  (plugging the cable and start tethering)
  alex@ubuntu_asus:~$ ip link
  (...)
  9: usb0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000
      link/ether 02:61:5a:5d:30:2c brd ff:ff:ff:ff:ff:ff

  But, when I try without network-manager
  (with cable unplugged)
  alex@ubuntu_asus:~$ sudo stop network-manager
  network-manager stop/waiting
  (plugging again and starting tethering)
  alex@ubuntu_asus:~$ ip addr
  (...)
  10: usb0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
      link/ether 02:61:5a:5d:30:2c brd ff:ff:ff:ff:ff:ff

  I tried many times and aways got the same result.
  I've found this problem in both raring and Ubuntu 14.04, but only in raring I have tested this soluction.

  alex@ubuntu_asus:~$ lsb_release -rd
