The Dualshock 3 is an upgraded version of the Sixaxis, the original controller for the PlayStation 3. It includes all of the features of Sixaxis, but also includes vibration support. The Dualshock 3 is wireless, but comes with a detachable USB plug, which you must use to connect to your PC. Using a Dualshock 3 on the PC is similar to using any other third party USB controller on your computer. The only thing required is drivers, which can be downloaded.
Download the ds3drv_1.02 driver to your desktop. This can be found in the Resources section.
Connect your Dualshock 3 controller to your PC with its accompanying USB cable.
Click the "Start" button in the taskbar and select "Control Panel." Click "System" and select the "Hardware" tab. Click "Device Manager."
Click the + symbol near "Universal Series Bus controllers." Select the Dualshock 3 controller.
Click "Update Driver". Select the driver you downloaded in first step. It should be on your desktop.
Click "OK." Your Dualshock 3 will now work with any applications that support USB controllers.
