[ubuntu-it] USB e ohci

[Angelo Gelmi [Web3king]]

Ho installato ubuntu sul mio portatile NB zv5452. Esso ha un chipset
nvidia Nforce3 a brdo che mi genera dei problemi con le periferiche usb.

I problemi sono  riconducibili al modulo ohci-hcd, infatti facendo:
dmesg|grep ohci

mi si presentano questi errori...
