I had the "Vive Input Utility" examples working with the "Vive Focus" but recently it stopped. Could anyone conferm that the Vive Input Utility is working with the Vive Focus and what I could possibly be missing? I reinstall everything a few times now.
There was recently a software update to the UI (on 02/01/2019) - it was not a firmware update but on the bottom right of the settings it had a higher version listed once updated (1.4.12 i think). Since then i noticed that the controller would require more constant recalibration.. Could this update be anything to do with the issue you are facing?
