I havent tried to get it configured yet myself. I have a x45 myself which is basicly the same thing.
I play atlot of X3:TC and with that game, it does have the problem with the buttons being constantly on. A fix for that game is
to put a, -ignorejoy 9 -ignorejoy 10 -ignorejoy 11 -ignorejoy 12 -ignorejoy 13 -ignorejoy 14, on the command line which lets you
use it perfectly. I dont know if crysis uses those command lines or not, but on x3 that will disable the 2 switches.
That might help someone if there trying to get it setup and has the same problem here.
