Game pad connected to Arduino

Is it possible? I found a library, but it seems to work just with a logitech gamepad..

I have a USB Host Shield and a wired USB Joystick (game pad), I want to connect the Joystick to the usb host shield and the usb host shield (duh) to the Arduino. Is there any library? Have someone did something like this?

please help!

We need links to every product/library listed!
