Simhub doesnt see my hardware

Hi!

I have sim hub installed and my mate Pete has given me a seat coshion to try out for the moment with Ardunios in it (no amp required). But sim hub is not regonising anything. Does see my wheel under controlers, also have selected correct board but its not recognising that either, keeps saying select comm port, but when its scanning for ports it finds none. Windows is recognising that the USB Ardinio unit is plugged in as it shows in the Device manager, but no drivers installed of course. Am I doing something wrong?

Thanks!
