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) :
