Installing the Arduino drivers under Windows XP
This is a guide to getting the Uno and Mega2560 working under Windows XP after the operating system has tried but failed to install the drivers. Please consider that the screens were made with a Uno board; if you have a Mega2560 just look for Mega2560 instead of Uno. For more information, see: getting started with Arduino on Windows.
