Behringer X-Touch Exteder Problem in Cubase Pro v10.0.30

Steinberg Lounge

I have one X-Touch and Two X-Touch Extender.
Only one X-Touch Extender works but two X-Touch Extender does not works simultaneously.

However one X-Touch and two X-Touch Extender works exactly in Studio One Pro v4.5.x

What’s problem?
