salve ho un problema con le card di memoria in pratica non le legge quando estraggo la memoria il led si accende per 1 istante quindi deduco che sia collegata bene. inoltre ho staccato i fili e li ho riattaccati ma nulla. ho aperto il terminale e ho scritto:

 ~$ lsusb

poi ho scritto:

1) qual'è la versione di Ubuntu?

2) hai provato a cercare l'errore su Google? Per esempio qui pare che abbiano risolto il tuo stesso errore -71, disattivando una certa funzione di autosospensione: http://ubuntuforums.org/showthread.php?t=797789
