[quote=bebo_sudo]Ciao Antonio,
Gentilmente, quando posti codice usa il tag code:
[code]cosi'[/code]
A sistema avviato, aprendo un terminale ed inserendo la chiavetta, dando:
$ dmesg -H
Vedi qualche riga recente rispetto alla chiavetta? potrebbe facilmente essersi fritta[/quote]
Ciao Bebo, mi da molte righe, non riesco a identificare eventuali linee relative alla chiavetta, ho lo stesso dubbio sul fatto che possa essersi fritta e che posso ormai buttarla
