Index: "Unknown" and "Valve VR Radio" don't have drivers on windows 7

[Error.mdl]

Just got my index today and I'm trying to set it up on windows 7. For some reason, it cannot find the drivers for some usb device (hardware id ACPI\PNP0A0A) and a device called Valve VR Radio. The headset turns on but is unable to communicate with the base stations or controllers. I realize that win7 isn't supported, but I'd really rather not move to 10.

I got mine to work without the "Valve VR Radio" driver. What I needed was the "Microchip HUB Controller" drivers:
