This is what mine looks like. My Avenger still has that box, plus I have a spare. I bought an old laptop that just gets used for it. I seem to remember having to download a driver, also. The cover tells you that I cant remember how to do it every time... Wasnt able to read a name or number off of the cable. Also, there are 3 USB portrs on the laptop, and it will only work if plugged into a certain one ?? Not sure why. Jim
