Instructions
Connect the DS3 to the PC, then open Device Manager (Start -> Devices And Printers.) Right-click on the PS3 Controller, then click the "Hardware" tab, then click "Properties," then the "Driver" tab.
Click "Update Driver," then "Browse for Driver." Navigate to "ds3drv_dx_1.02," then click OK. This makes the controller usable.
Navigate to where the "ForceFeedbackDriver" is located and right click it. Since it is an .inf file, it has an option to "Install" in the context menu. When a game is launched, the force feedback application shows in the tray, allowing you to control rumble settings for the device.
