Morkar: It's a while but I was resinstalling I-War 2 and it may be useful for others:
My old Cyborg Evo Force wasn't getting recognized and I tried everything (installing the driver again, make it priority device in win etc., unplugging my second keyboard/HID etc).
But the solution was rather easy:
under your gamepath e.g.
Independence War 2 - Edge of Chaos\configs there is the default config-file which has the keymapping in it. There I changed everything that was listed as
Joystick1 to
Joystick2.
Worked flawlessly and I got to enjoy a great game again!
This worked with my CH stick and pedals mapped to one device. Thanks!
