NetworkManager & problem with Vodafone Internet Key Huawei

["maurofolc tiscali it" <maurofolc tiscali it>]

Hi !
I need help. I try, without success, to make work my USB Vodafone 
Internet Key.
Looking at "lsusb" I see:

Bus 002 Device 002: ID 12d1:
1520 Huawei Technologies Co., Ltd.

I use Fedora 14, with kernel 
2.6.35.13-92.fc14.i686.PAE
and I have installed the following 
NetworkManager packages:
NetworkManager-0.8.4-1.fc14.i686

NetworkManager-gnome-0.8.4-1.fc14.i686
NetworkManager-glib-0.8.4-1.fc14.
i686
NetworkManager-openconnect-0.8.1-1.fc14.i686

I have also 
installed the package: ModemManager-0.4-4.git20100720.fc14.i686

I have 
created a "new connection" in NetworkManager, in the 
"Mobile 
Broadband" section, flagging to "connect automatically".
But nothing 
happens: no connection. That choice is not visible
in the NM applet.


Where is my mistake? 
Thanks
Mauro
