After recently upgrading my graphics card to GTX1080 (worked well with my GTX780 but with performance limitations) and not paying attention to what USB 3.0 port I used for the specific devices I had recurring sensor and HDMI failures. The only way to get around the issue I was able to find by trial and error is to plug the sensor to a USB 2.0 port.
Reading all the issues with regard to USB connection of the rift I assume that my USB 3.0 Ports are not able to provide the power/current required by the sensor and/or headset. According to the motherboard manufacturer the USB ports are according to USB 3.0 standard.
Due to not having had any issue with other USB devices I assume that the current drawn by my rift is either n the edge or over the rated power for USB 3.0 ports. Was not able to find any information what maximum current is specified for the sensor and headset.
Could you please provide this information?
