Getting a USB Logitech Rumblepad working on Linux is not too hard. Here is how i did it. Logitech ignore Linux so do not provided any drivers or help. 🙁 Most are already catered for by the kernel.

Test the Rumble pad was found

We shall start off by checking that your joystick has been found by the system. Make sure your joystick is inserted into a USB port.

You should see a line talking about Logitec rumblepads.

cat /dev/input/js0

If you see some unusual characters on the screen it means Linux found your USB rumblepad. (It's a good sign).

Install some software

Okay time to install some software. This will allow you to calibrate the rumblepad.

sudo apt-get install joystick

joystick is a package that contains a number of tools these can be used to calibrate the gamepad from the console.
Start by using jstest. Press all the buttons and joysticks. The output on the screen will update in real time. Make a note of what jstest calls each button and joystick. You will need these for jscal. It is also worth making the terminal wide as they can be a lot of data bing displayed on one line.

jstest /dev/input/js0
jscal /dev/input/js0

I said Getting a USB Logitech Rumblepad working on Linux was not that hard. Shame Logitec cannot be bothered to even do that much.
