I know there are threads about this but I was so impressed with this solution I had to put this on its own thread. This may not work on black screen that happens when u first set up but should if you have my described problem. I saw a u tube video that said on windows 10 go to USB selective system settings. Then select disable. I did then shut the pc down restarted. I did this yesterday. Then I went in and out of oculus 5 times and all was good. I hope this helps.
