[bglug] Problemi di connessione 3G con MF622 aka MDC502HS

[Jimmi]

Mi chiedono assistenza per il modem usb MF622 con Ubuntu 9.10. Ho  
trovato questa pagina [1] sul wiki e pochi altri post.

Ho seguito la modifica in 10-modem.fdi e quella descritta per la 9.10,  
ma non la ricompilazione del kernel, ed ora il modem mi viene  
riconosciuto da Network Manager se lo attacco al boot. Se però tento  
di connettermi nei log trovo:

uhci_hcd and address 7

Qualcuno ha già usato con successo l'apparecchio?

Oppure sapete dirmi come posso fare in modo che pppd usi una delle  
delle altre due interfacce, /dev/ttyUSB0 o /dev(/ttyUSB2?

Grazie
