Please if you have time explain to me a little regarding what drivers I need to use and what language etc. I am using windows xp.
Have you installed the "arduino" drivers, and can you download a program to the arduino?
If so, you are done - all the drivers are present and accounted for.
Sorry, but I can't offer any advice on Windows code to talk to a serial port - I don't do windows. I can guarantee it will be easier than trying to interface a usb device with libusb, though.
