Nessuno di voi è riuscito a usare una penna/hd usb 2.0 sotto linux 
sfruttandolo al 100% ?
Purtroppo caricando il modulo ehci (l'unico che gestisce le periferiche usb 
2.0) la mia penna non è riconosciuta come un usb storage device, quindi non 
la vedo. L'unica soluzione è stata quella di non usare il modulo ehci, ma 
quello ohci; in questo modo la penna funziona regolarmente, ma la uso come 
una periferica usb 1.1 e non 2.0!!

Ecco l'output del kernel nelle due situazioni:
