Grazie, ho risolto seguendo passo passo la procedura suggerita, ma solo dopo aver installato usb_modeswitch versione 1.1.1 e l’ultimo data package datato 22/3/2010.
Non so se sia ortodosso, ma solo in questo modo il mio sistema riesce infatti a commutare la chiavetta correttamente in modem (lo fa in automatico una volta inserita) e a creare i relativi device.

A questo punto con wvdial funziona!
In ultimo, c’e’ qualche utility da consigliare per monitorare il tempo che si rimane connessi?
Grazie ancora!!
