I still have an analogue CH stick and an older Thrustmaster set of rudder pedals. I now either have to get an old sound card with a joystick port or just break down and buy another stick in order to play aircraft games again.
At CH-Hanger there used to be a program that allowed you to use the old analog CH gear and Speedkeys in XP, though I can't tell you how well it works, if at all.
You can also buy an analog to USB game port adaptor if you don't have an old legacy analog game port.
