The Playstation 3 Controller is not supported under Windows without installing drivers so it will not work with the Driver Station app.
Having said that there is a very similar controller that will. A
Logitech Dual Action gamepad will run you about $20, is very similar to a PS3 controller and will definitely work with the Driver Station (we used one the past two years as our "operator" controller).
The Dual Action does not have the gyro/accelerometer feature, the buttons are not pressure sensitive like a Ps3 controller and there is no force feedback.
