That is strange, as I also use a ASUS laptop (G53SW), and it connects fine. My next suggestion would be to un-install the Black Magic software from the ASUS and re-install it.
Out of curiosity, do you have any other BMD products’ software installed on the ASUS?
I know that the ATEM’s software and the Intensity Shuttle USB’s software don’t play nice together, I think Media Express is the culprit in that case.
