If that controller is compatible (it probably is) then it should be as easy as setting a reference to the Microsoft.Xna.Framework (you will need to first download and install XNA game studio 3.0 SDK which is free)

Once you do that, you will be able to set the above reference in your code.

Then (as far as sending rumble) it should be as simple as

Code:
GamePad.SetVibration(PlayerIndex.One, 1, 1)
the two 1 values being passed are for the left and right motor (assuming it has 2 vibration motors like the 360 controller does) I would imagine if it only has 1, then one of those values is ignored. The intensity of the vibration is any value from 0.0 (none) to 1.0 (max vibration)
