Re: USB error

E poi:

psycosm@sith:~$ dmesg | grep usb

Ho provato a montare il dispositivo ma mi dice che il filesystem non è 
valido, il che è impossibile perchè l'ho già montato su debian (nel 
vecchio pc) e fa così con qualsiasi altro dispositivo connetta.
Suggerimenti? Io non ho proprio idea di che fare!
