Well im an abselute retard for most computer things so dont blame me if I sound stupid. Well the thing is I wan to get USB 2.0 (as im getting an external DVD writter) but I have no idea how to do it. Is there any way of getting USB 2 without putting stuff in my computer (as I dont want to bugger things up) and if I had 2 would the existing USB ports become USB 2 or would I have to change them? I saw on ebay once this thingy that plugged into some big socket at the back and said it was USB 2.0 just using something different(1 end was usb the other some big wide thing). Well thanks if you can help.
