Yes, the game supports Xbox Controllers. If it is not working for you, can you please let us know what exactly the error is? Until then, as a troubleshooting, make sure Xbox 360 Controller is enabled from your PC control Panel. Then launch the game, go to settings , option, Controls and click Customize Controls. This may differ from game to game but find similar option. Here properly select Xbox controller. If still not working then probably you will need to download and any Saints Row IV PC game patch from its official download sources.
