[ubuntu-it] Problema con Huawei E1692

Ciao a tutte/i,

sto battendo il capo con un problema che non mi era mai capitato prima.

PREMESSA

qualche mese fa andai a casa di un'amica per convincerla a passare a
Linux. Portai il mio portatile, lo provò e - in un batter d'occhio -
configurai la sua chiave internet della TIM, di cui nell'Oggetto della
mail, una Huawei E1692.

Dopo un po', convinta, mi chiese consiglio su un portatile super
economico da prendere, e dopo aver letto una buona recensione le
consigliai un Asus X501A:

Al di là che il portatile arrivò e non faceva boot, per cui fummo
costretti a riportarlo in assistenza; e che una volta tornato lo trovai
con ubuntu 11.10 installato, una volta aggiornato alla 12.04 sono
passato a configurarlo - senza problemi di sorta - fino alla fatidica
chiave internet:

non c'è verso di fargliela vedere.

Cioè:

vede l'interfaccia usb, ma non come modem.

Sul pc fisso di casa mia - sempre una ubuntu 12.04, aggiornata tanto
quanto quella del portatile in questione - appena attacco la penna:

Ed è pronta a funzionare.

E stop, il sistema non rileva nessun GSM modem sulle  ttyUSB*

Ho cercato in giro in rete, ovviamente, ed ho letto varie guide, tra cui
questa:

http://www.lffl.org/2011/02/ubuntu-risolviamo-il-problema-con.html

o altre simili, ma nessuno soluzione ha funzionato.

Suggerimenti? Idee? Consigli, prima che sia costretto a dirle di passare
a Windows...

A monte dei compagni che sbagliano (secondo noi) ci sono, i compagni
assenti, gli indifferenti, gli accidiosi, i nemici latenti e via
seguitando fino ai nemici puri e duri.
Sarebbe opportuno tenerci cari i primi e cercare di conquistarne di
nuovi tra i secondi, invece di promuovere polemiche che servono solo ad
alienarceli tutti.
