Ok, I just fixed mine. Hopefully this can help some of you too. I had to go into device manager, and change the driver for the ASMedia USB3.1 eXtensible Host Controller. For some reason, even though that controller works fine for other USB 3.0 hardware, it causes problems for the Rift S.Right click it, choose "update driver", then choose "browse my computer for driver software". Choose "let me pick from a list..". Untick "show compatible hardware", choose "(standard USB Host Controller) from the menu on the left and select "USB xHCI Compliant Host Controller" from the box on the right.This will replace the ASMedia USB driver with a generic USB3.0 driver from Microsoft. As soon as I did this, the Oculus Rift S sensor check worked fine, and I could use the Rift S without and dramas.
