Ecco cosa esce quando collego la chiavetta, nonostante abbia seguito la guida alla lettera:

In pratica come se non avessi fatto nulla...
Ecco cosa esce col comando lsusb:
Bus 007 Device 004: ID 1bbb:f000 T &amp; A Mobile Phones <br />Bus 007 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub <br />Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub <br />Bus 005 Device 003: ID 05e3:1205 Genesys Logic, Inc.

Infatti sulla riga Bus 007 1bbb:f000 dovrebbe cambiare in 1bbb:0000, ma non cambia...
Ho provato anche a rifare più volte la procedura dall'inizio, reinstallando anche usb_modeswitch, ma niente da fare...

Come passi i parametri tramite usb_modeswitch? In modo esplicito, ovvero in questo modo:
usb_modeswitch -v 0x1bbb -p 0xf000 -V 0x1bbb -P 0x0000 -d 1
o semplicemente digitando:
usb_modeswitch
?
L'opzione -d 1 dovrebbe permetterti di rilevare il modulo usb-storage.

UPDATE:

ho aggiornato il pacchetto usb_modeswitch, forse l'ultima volta che l'ho reinstallato ho messo una versione vecchia...

Ora con:
usb_modeswitch -v 0x1bbb -p 0xf000 -V 0x1bbb -P 0x0000 -d 1

MI esce:

Bye.

Ma ho sempre lo stesso risultato:
Bus 007 Device 002: ID 1bbb:f000 T & A Mobile Phones

Ho provato un sacco di volte...
