VKB-SIM

Strange question, but I usually play American Truck Simulator and ETS2 and it's common to use a Button Box for auxiliary truck controls.

And I think gnx SEM perfect for using some functions.

Could anyone tell me if Vkbsim gnx SEM is recognized by these two games?

Not sure if it's recognized or not, but you could use it anyway by binding all the buttons on the SEM (or any other device) to keyboard. Guide on this procedure here, takes only a few minutes.
