Up to this point, everything is expected. The vid of this device does
not match any existing plugin, so MM should try to probe with the
plugins that support vendor probing via AT (e.g. for RS232 modems).

This line above is wrong. The nokia plugin should require AT probing,
and it wasn't run. This is something to analyze and fix, I have not
yet found a reason why this happened.
