Dual input devices Steam FS 4 ?

    Hi, a newbie question when running Steam FS 4 on Windows 10
    Have a Saitek Flight Yoke System on one USB and a Saitek Flight Rudder Pedals on another USB
    In Controls Input devices I can select just one of the devices, not both.
    Is this correct ? I've seen conversations in FS 2 Fora but not for FS 4

    Regards Erik
