My motherboard has a USB slot at the back that says "VR ready". I don't know what PCIE you're talking about. I have the headset plugged into an RTX 2080 and USB goes into that VR ready 3.0 USB slot. I know what PCI slot is. I don't know what changing those would do since the Index isn't typically plugged into them or am I mixing up slots here? I don't think I've needed to update my bios ever. Are you suggesting the headset isn't getting enough power or there's a data problem? I don't think that could be it since it works just fine it's just that tracking is off with the controllers and the base stations vanish and a grey flash occurs often.
