R: NetworkManager & problem with Vodafone Internet Key Huawei

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

I reply to myself, as I want to add some new information. 
Now I got 
my connection start, but the modem hangs up 
and the connection doesn't 
succeed.

I configured usb_modeswitch to change   idVendor=12d1, 
idProduct=1520
into  idVendor=12d1, idProduct=1465 

... and added a 
script to do some "modprobes". Here are the modules loaded:

# lsmod | 
grep option

option                 13257  1 
usb_wwan                
8194  1 option
usbserial              28113  4 option,usb_wwan



Here 
is the log's detail.  Could anyone tell me some hints to get my 
usb 
device work ?
