Andrew,
The US-800 is a class compliant device and the US-600 is not, that is why you are facing that issue. I apologize for any inconvenience.

Your Question:
I have bought the US 600(as the 800 has now been discontinued), work with DAW app on my IPAD 2, but it says USB device cannot be recognised. Why does the US800 Work according to this link http://www.youtube.com/watch?v=dVgotmBPG7o . Now according some forums it doesn't work on the US18000 either,
