If you have a HOTAS with a ps/2 cable connecting the throttle to the stick, like a X52, then be careful cause the metal pins on the end of the cable are really quite fragile. If you unplug them too hard, they can become bent out of shape, which can sometimes be fixed by bending them back with a tiny needle.
I made this mistake yesterday, and I now have to find a replacement.
