I had same problem with Win7 ,if i pushed the i button at Hotas the HUT LED at the Joystick did flash and I could use some buttons ore the scroll wheel
-If you dont use the SAITEK programm,uninstal it
than use another usb port for youre x52 ,if the LCD Monitor on youre HOTAS have no light than you can use all buttons for AH again.
good Luck
