Can The Numark Mixtrack Pro 3 Work Using a Powered Hub Connected To The IPad Air?

My son loves the Mixtrack Pro 3 and wants to use the app Djay Pro using the IPad Air .When I connect the Mixtrack to a powered hub it goes through a non stop flashing light show. This renders the controller non useable. Yet others say it will work. What USB hub should I be using? I have the camera connection kit with the lightning lead but can’t do anything until I sort this issue out.
Your help would be very much appreciated

I have this USB Hub. Work with all Controller

If you buy this Camera Connection Kit from Apple Tagen you also can charge your iPhone while connected to Controller
