Sul mio Acer Aspire 5100 ho Ubuntu 10.10 installato 3 mesi fa.
Tutto funzionava alla grande.
Ora son due settimane che tutte le porte USB del portatile funzionano un po' sì un po' no.
Sulle porte ho essenzialmente collegato mouse e tastiera esterna.
Capita che il mouse va per qualche secondo, poi si spegne, come se non arrivasse più l'alimentazione.
Ma altre volte non arriva mai.
Il problema non accade mai su tutte le usb insieme.
Dalle prove fatte, con un "lsusb" mi rileva le periferiche solo quando le porte usb vanno.
Mentre facendo un "lshw" ho i seguenti dati:
