Running the Mixed reality Portal the the compatibility screen says "You're good to go" with ticks on all apart from the Graphics Card (Laptop has x2 GTX 860M which is WDDM 2.2) - which has See Details written next to it.
When progressing to the next screen however it shows "We couldn't find your headset..."
The Acer AH100 is present in the Device Manager & the USB reports the HoloLens Sensors -
Any ideas as to why the Portal isn't seeing the headset ?
