So I got a new Pcie USB 3 board (NEC uPD720201 chipset) that get the green light in the compability tool. But i cant get the sensor to work on it. Headset work fine and if I use the sensor on an old USB2 connector it works fine. But not on the USB3 card.
Solved. Make sure you usb3 pcie host drivers are the correct ones. I went in to the device manager and hit "update drivers". It then removed the latest drivers from the hardware maker and put it the standard Windows drivers instead. And problem solved.
I had to fiddle with the drivers as well to fix this. I even bought the 7 port version of the suggested USB card. Unplug ALL your USB devices and plug in the Rift and sensor then restart. That's what got for me.
