In response to comment#20, I can confirm that that connection is
possible with a kernel downloaded from http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.17.4-vivid/linux-
image-3.17.4-031704-generic_3.17.4-031704.201411211317_i386.deb.

This was tested on Ubuntu 14.04 (Xubuntu).

Note I used a manually created NetworkManager configuration file stored
in /etc/NetworkManager/system-connections. Connecting from the Blueman
control panel does not work (says "NetworkManager did not support the
connection").

Title:
  Network manager fails to find bluetooth 'modem' for dun connection in
  saucy and trusty

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Working on kubuntu saucy 64bit. Trying to connect to the internet via
  an UMTS phone that is DUN capable over bluetooth (Samsung galaxy)

  Setting up things manually, i.e.

  bring up rfcomm via rfcomm command
  use kppp to connect

  the phone can provide internet access just fine.

  Trying to do the same with network-manager does not work.

  I have the profile set up in a file in /etc/NetworkManager/system-
  connections/

  when I try to connect, things start just fine. Connection confirmation
  is asked on the phone and the rfcomm interface is brought up. However,
  network manager says that it fails to find the modem. In syslog I get:

  Note that after the 'device configure' phase, giving the rfcomm
  command on the console shows the rfcomm interface up and alive.
