When starting computer Renesas USB 3.0 eXtensible Host Controller - 0.96 (Microsoft) and USB 3.0 root hub missing from device manager. Sometimes it reappears after I restart the computer. Most of the time it does not reappear in the device manager hence I could not use the USB 3.0 port. The USB 2.0 doesn't have this problem.
I suspect a recent windows 10 update affected it. I don't have this issue before.
