I’m getting the same error. I’ve looked at the logs as Mr. Burgin above has done and get the same data. I have tried every remedy that has been discussed on these forums and on the Elite forums. I’ve installed then deleted all the Tobii files several times. I verified the USB 3.0 ports on my MB, they are Intel, then even ordered and installed the Tobii recommended USB card. All function properly. I just now reinstalled all the Tobii files, and reconfigured Tobii EyeX and Infinite Screen. Calibration is fine, I can break the dots, but when I launch Elite Dangerious Horizons (64), no joy with Tobii eye tracking. I’m very frustrated and would like an answer from Tobii to get this solved.
