My Rift S has been working well all week. Today it has started showing an orange indicator in the Devices section. In there it displays the warning:
USB driver update recommended
When I go into the headset it has a warning triangle next to USB. When I hover over the ? it shows the following tooltip:
Your headset is plugged in correctly. If you encounter tracking issues, updating your driver (Intel) may improve performance.
I have made now changes to the PC so don't understand why this message is suddenly being displayed. All my USB drivers are up to date so I'm at a loss on how to fix it. I am currently opted into the PTC and have 220.127.116.116587 installed.
