I've gone through all of the obvious things... tried other USB ports. Moved my desktop display to an alternate port ... my video card only has one HDMI port. I've plugged and unplugged the cable on my HMD. Powered on/ powered off my computer several times. Verified that no USB power management settings are in place. How do I contact support to get a new cable?
BTW - I meant that my video card GTX-1060 only has one HDMI port ... but it has multiple Display port ports that I moved my display to just as a troubleshooting measure. My config had worked for weeks and today ... HDMI disconnect ... permanently.
