To those getting the warning that you’re not using a USB 3 port: I got that warning when I installed the Oculus software, but everything works fine nonetheless. I also have a warning in my Oculus home all the time that DK2 is not supported, but I haven’t find a single program or function that hasn’t worked, so I think it’s mostly a way for Oculus to not have to answer for any problems that might arise, so mostly a legal thing. So, before you try anything else, test if it works or not. If it still doesn’t work I’m sorry I can’t help since all my installations have gotten the error messages and all of them worked flawlessly.
