I am waiting for amazon to ship my prime but i want to use a ps3 controller for games. I dont want to buy the dock so i seen the asus usb adapter (90-XB2UOKEX00010). I cant see why this wouldnt work but has anybody had experience using this usb adapter? Below is a link for where you can look at it.
