I'm having a strange issue where the Rift no longer responds. I was surprised to see that in Oculus it was missing from devices. I restarted the machine, unplugged the headset and plugged it back in. I even uninstalled and reinstalled Oculus. No matter it still doesn't show up and does not give any indication that it functions. I am currently running an Nvidia Geforce 970 with driver version 390.65 but I can't roll it back any farther and this doesn't sound like the black screen problem others are reporting.
Does anyone have any ideas?
