when going through the thread as well as this one here: http://developer.tobii.com/community/forums/topic/moved-could-not-connect-to-eye-tracker/
The ASmedia doesn’t seem to be the most reliable USB 3.0 controller. On the internet there are several reports about problems also with other USB 3.0 devices.
I haven’t seen any Asmedia working with the EyeX, yet.
We have ordered some motherboards with Asmedia controllers and will have a more detailed look at it, but this may take some time.
Any chance you can acquire one of the tested ones?
