After installing Oculus App,App says "Connect HMD and USB3 to my pc." Of course I connect them to my pc,but it doesn't act at all. About 5seconds after, App always down and App restart automatically. After repeating this situation,finally I got error message like attached picture. Many Japanese user have same trouble, according to Twitter.
