Wanted to Play PS3 with my MOUSE and KEYBOARD

I am an OLD PC gamer and I used to play Battlefield 2 on PC with a mouse and keyboard. NOW I have a PS3 and I need to play with the controller....however this is so crazy out of hand at how fast the joystick is that I decided to buy an Eagle Eye Converter to allow me to use a mouse and keyboard on my PS3.  I purchased it on Tuesday from Amazon (Penguin United) for $54.67 with Free "PRIME" shipping. Setting it up was rather simple until I had to do the calibration in game BUT I found that if there ever was a time to "READ THE INSTRUCTIONS" this was it. After reading the instructions I was able to use my mouse and keyboard with my PS3.
