Cool info and thanks a bunch for it. Could you tell us what make and model usb keyboard your using that has an internal hub? I'm having trouble finding one.
sorry, 'shock, but I have had the keyboard for quite a long time (I bought it specifically for when I chipped my xbox and was going to use a USB keyboard, but it didn't quite happen that way).
all I can say is that it's a Silitek one with internal hub allowing a kind of "pass-through".
I can only suggest going to a PC store where they have keyboards on display and trying one!
