When you execute it you will get a series of pop-ups showing that it has recognised the hubs that the devices are on. Then you get the main application which gives you a hierarchy of the devices. It may take a bit of experimentation to determine which device is which, but if you keep everything plugged into the same ports, you will soon figure out which is your wheel, joystick or whatever. Then to reset your device, just double click on it... it will power down and then back up again.
Remember this is just to emulate unplugging a device and plugging it back in again... as we have to do when out wheels lose centre.
