Any controllers that Windows can see work with AH. In Windows 7 go to Control panel, choose Devices and Printers. You should find your controllers in the upper row. Right click any of them for Game controller settings which allows you to test and calibrate all your controllers. Something similar should work in newer versions of Windows, too.
When you've found and tested your controllers in Windows, start the game and open the clipboard. Options>Controls>Map Controllers. Select the controller to be mapped and assign the feature you wish from the opening list.
Notice that there's four modes available. You can copy mode 1 to all of them if you wish, or you can create different combinations and settings for planes, vehicles etc.
