I just downloaded the new drivers for the Rift S. After they had
downloaded and installed, all of the USB ports on my PC had stopped
working. I’ve restarted (manually) to no avail. I can’t even open my PC
because I can’t connect my keyboard or mouse.
I figured my only option was to try to restart my PC again (because I
could not use keyboard or mouse to control it). After restarting again,
everything went back to normal.
