Public bug reported:
When I plug my Motorola XT910 (Razr Max) as USB, with connection sharing
on USB enabled on the phone, network-manager sees it, but reports it as
disconnected. If I activate the usb0 interface manually (ifconfig /
dhclient), it works, flawlessly.
I set network manager to log debug info, this is what I get, once the device is
plugged in (MAC & S/N removed) :

I have no idea how the "connected" state is detected on cdc_ether, so I
assume network-manager simply doesn't know if it's up or not. On the
phone side, it's "up as can be", but maybe something is not reported as
it should. It's possible. I didn't find a way to fake the connected
state on NM's side.
This is on a updated Ubuntu 14.10, running either the 3.16 kernel from Ubuntu,
or the latest mainline one (3.18).
% NetworkManager --version
0.9.8.8
package is 0.9.8.8-0ubuntu28.
Maybe udev is involved as well, so udev is 208-8ubuntu8.1

I have no idea how the "connected" state is detected on cdc_ether, so
I assume network-manager simply doesn't know if it's up or not. On the
phone side, it's "up as can be", but maybe something is not reported
as it should. It's possible. I didn't find a way to fake the connected
state on NM's side.
This is on a updated Ubuntu 14.10, running either the 3.16 kernel from
Ubuntu, or the latest mainline one (3.18).
% NetworkManager --version
0.9.8.8
package is 0.9.8.8-0ubuntu28.
Maybe udev is involved as well, so udev is 208-8ubuntu8.1
