HID Joystick classes - Vibrating Joysticks

[enrique]

Does any one know of a way to access the windows DirectInput Interfaces with the winriver/frc available headers and classes?
I didn't see anything in the hid or joystick headers.
The end result desired is to call the DirectInputEffectDriver interface to cause a vibrating joystick to vibrate. Or if there is any other way you know of vibrating a joystick programatically please enlighten me.
