HidJoy

Some games don't support multiple devices. If more than one gaming device is connected - the game won't work properly. (One example is Richard Burns Rally.)
This tool solves the problem by hiding the devices from the game.

It also has an option to hide the device from only one plugin module rather than the whole game. This option is relevant for X-Force plugin of X-Plane. X-Plane is a game, properly supporting multiple devices, while the plugin has bug preventing more than one device.
The tool allows both the game and the plugin to work properly.
