I have been setting up my Gamecube controller using a controller adapter (http://www.amazon.com/GC-Controller-Adapter-for-PC/dp/B0089NVTDM) which has been working perfectly fine for singleplayer use, but when I tried adding in my second controller and configuring it, nothing happens. I am assuming it is because it takes up only one USB port. But when I try to press any button on it in the config, nothing happens. Does anyone have any experience with any adapter using 2 players using one port and by Mayflash?
