Now, i use TrinusCBVR and Driver4VR and i have bluetooth controllers (joycon and gearvr) connected to my pc all the time
The problem is when i try to set keys for example sensor reset, it only accepts controller inputs and not keyboard

This issue can be reproduced with ease
Connect USB or Bluetooth controller
Go to sensor tab
Try to set a new key for resetting sensor

If it does not work, try pressing a controller button and i’l work on the controller only
