Hi @ar2r,
I have tried to find someone with the issue you are having however when it comes to ASMedia chipset as you pointed out, there are many issues and consequently we warn users against this. That being said, you mentioned that the eye tracker behaved somewhat similarly on another (Intel) system. could you kindly show the event logs when the eye tracker is used on the system please? If they are the same if may indicate that unfortunately there is a physical problem with the tracker. So, kindly let me know. Thanks.
