Comment 5 for bug 286859

Unfortunately it is even harder and not easy to fix for those cards.

Danny and me have the same card (hp hs2300, a relabeled sierra wireless) in very similar machines (mine is a hp 2510p, danny's is a 2710p).

And now for the good part:
- my machine has ttyUSB2 as "command" and ttyUSB0 as "ppp" port
- dannys machine has it the other way round.

In umtsmon we solved it by querying the ports with "ATI" and parsing the answer (it is different on both ports).
However, this looks out of scope for NetworkManager.

Danny, could we add a small helper to HAL that probes the ports of such cards and then assigns the ports correctly (instead of statically adding them via a FDI file)?

Then NetworkManager can just use the corresponding tags on the ports to select which port to use for PIN entering and for ppp.
