You have 2 options:
Get a Deneb USB card
Get an Xsurf ethernet card and get a subway USB expansion module.
Neither are truly valid options as Deneb & Subway USB keyboards & Mice do _NOT_ work in games which are not OS friendly (i.e. WHDload)
gazgod & Rebel-CD32 have the right / best solution. Adapters which plug into the existing Keyboard & Mouse ports which will make them 100% compatible.
