MacBook Air 2017 Monterey ANT+ USB does not show up

Hi,

I try to use my MacBookAir 2017 with Monterey and a Garmin ANT+ device to connect my tacx Vortex and fenix 6.

Want to use it with the tacx trainer app on the MacBook.

Unfortunately the ant+ device does not show up in the app. Also Garmin express does not connect to the fenix 6.

In tacx trainer only bluetooth is available, but I want to use ant+ because it seems to be more stable.

Booted with ant+ plugged in and tried to remove and plug in again - without succes. Garmin express told "ant+ receiver recognized but no device found".

How to setup my devices with ant+ in tacx trainer?
