Schmidt - Your CH USB controllers can be "combined" into a single device in Windows very simply.
Use the CH Control Manager software that came with them to "merge" the controllers. Â This will allow them to be seen in Windows as a single device, thus allowing games with single controller limitations to see them both. Â If you like you can always download it for free from our web site HERE
In fact you can merge as many CH USB controllers as you would like into a single controller for ArmA
Chris Death - You are right... it is up to both software developers AND hardware manufacturers to do their part and make sure that the integration of both product lines is a simple as possible. Â That was my excuse for installing the ArmA demo on my work PC
