[ubuntu-it] Scheda usb2 che non mi fa montare dischi

[eminux]

ciao,
sul mio computer fisso ho istallato una scheda usb2 (essendo il pc un p3
era dotato solo di prese usb1.1). il problema è che quando cerco di
connettere periferiche usb2 queste non vengono montate...
vi posto qualche errore così potete capire quello che accade.

stesso errore se collego il mio disco esterno...
avete idee su qualche modo per capire se è un problema di hw o di sw?
grazie 1000
