I have tried a different usb port , with and without an extension cable, same result - the ant+ dongle is working fine for heart rate monitor and for the bkool2. (powersource, cadance and controllable).
It looks like the vector pedals is not sending any ant+ informations).
i’m using V3 pedals with a kinetic R&R, using an old 2011 era IMac, with Ant+ and bluetooth (dongles, (newer version that imacs built in BT… some times BT needs to be turned off, dongle disconnected, reconnected then BT turned back on))
I can connect pedals using Ant+ or bluetooth without any problems for cadence and power
( have to make sure trainer power isn’t connected and using BT make sure other devices iphone, ipod, ipad… haven’t claimed the pedals bluetooth. Ant+ can go to garmin 803 at same time)
