Hello everyone, I just joined cosmos. I installed and updated according to all instructions, including USB and software, but it always displayed code: 200. Then I removed all the software and USB driver and steamVR and reinstalled it, exhausting everything I could find on the Internet. It finally worked after an accidental reinstallation, and I was able to play for hours at last, but when I shut down and rest, and then reopened it, I returned to code 200, and I was very frustrated. It was a really bad experience. My computer is MSI GS65. Also bought in the third quarter of 2019, USB is 3.0. I really can't find a solution .... I am very troubled. I hope that experienced users can teach me how to fix it, sincerely appreciate it.
