2 joysticks

I’d like to use 2 Joysticks with QGContrl- (I bought VKB Left Hand
Grip and Right hand Grip- each one has a its own separate USB), LEFT
one for throttle, and back-up X, Twist-z, is it possible? Assigning of
2 USB PORTS joysticks. QGC seems to recognize them both in the Joystick
selection, but does not give simultaneous display (PC).

Redrc

Anyone ??. It only allows 1 stick at a time, or is there a parameter I can change to allow both simultaneously?
