HP Headset Not Being Detected At All
-Bought a refurbished HP Windows Mixed Reality Headset. At first the Mixed Reality Portal wasn't recognizing my USB 3.0s. I looked that up and uninstalled the non-Microsoft eXtensible Host Controller, now the Portal recognizes the 3.0s.
-I have green checkmarks for everything in the Portal. When the Portal tells me to connect my headset I plug in the USB into a 3.0 slot, then the HDMI to the back of my GPU and nothing happens at all. I've checked the troubleshooting guide and googled the problem and haven't found a solution. I've tried all the other USB slots. I've successfully plugged a monitor into the HDMI slot. I've checked all of my drivers. I even uninstalled and reinstalled every USB driver and all motherboard drivers.
-The other end of the USB/HDMI cable that plugs into the headset got rather warm the first time I plugged it in, I don't know if that means anything.
-I plugged the headset into an older, non-compatible computer to see if anything would pop up. Nothing did.
-The controllers paired up fine through the bluetooth.
-I cannot install the drivers manually because nothing shows up in Device Manager when I plug in the headset.
