USB 3.0 + DJM

Anyone care to share some user experiences about using Pio's DJ Mixers via USB 3.0 ports?

Sorry if this topic's been done before but I only found articles confirming that some users have had luck with the DDJ T1 working properly.

I've got a brand new DJM 850 and just ordered the retina MBP and would appreciate any comments on the matter.

Thanks!
