I have an Ericsson F3307 device which is showing up in udev, but is not
marked as ID_MM_CANDIDATE. Of course this messes up modem manager because
it sets the device property to ttyACM0 instead of usb0.
As shown below, other devices (eth0, etc) are getting marked. Is this a
problem that people have seen before? Maybe it is a problem with my version
of udev? 146?
