Thank you for all the tips, unfortunately I still can't get the HMD recognized after following step by step the "Rift not detected on win 8.1".
The camera shows up in the manager as "Camera DK2" after having it plugged to my PC and the rift as "USB device".
Once the oculus runtime is installed, and the HMD driver uninstalled. I reboot, and get the camera showing up as "Oculus Positional tracker" and the rift still as "USB device".
There seem to be some kind of driver problems between the last runtime and Win 8.1...
I had the rift working without any problem for hours, and one day...without any sign It do not want to be detected, I just got that orange light of death... :twisted:
Seems to me the rift is "stuck" in some kind of sleep mode, because I can hear the win "plug, deplug" noise.
Now I am looking for some possible troubles caused by "Asus Instant on" (got an Asus PC) but without sucess. I'll let you know if I find something.
So, once again, thanks for this complete Tip list that will for sure help a lot of persons. 🙂
