I have had my Rift S and before that Rift CV1 since launch - plugged into same PC since then and never had any issue with any of my USB ports.
However since about a month ago I have to unplug my Rift S usb connector and then replug it in every time I reboot my PC. Otherwise I cannot use the Rift S due to a hardware notification telling me my Rift is not working and I have to plug into a new USB port. That is wrong because I just reuse the same plug and then it works, I have tried every other USB port and the problem still manifest each reboot.
It is really annoying as there is nothing wrong with my USB ports, the problem began when I subscribed to the Test channel whilst on the version 16 release, which worked fine. But then even unsubscribing and going back to v16 the problem remained and now with the v17 full release update I expected it would be fixed and it is not.
Has anyone else encountered this ? Is there any workaround or fix to prevent having to unplug and plug back into USB upon every single reboot ... so crazy really and frustrating as it seems Oculus do not reply anymore on these forums regarding such problems.
