Yes, it requires its own USB port.
It will work well with any joystick in Aces High because it works as a separate controller. In games that only support one controller, like Falcon 4.0, you wont be able to use them.
Get them. Then save to go for an all CH setup, one part at a time (3 parts total, $100 each)
When all your controllers are CH, you will be able to combine them into a single controller, which is neat for older games.
