I intend to buy a Blue Yeti microphone later today. I've been reading that you need two things for the yeti to work with GarageBand on iPad: the Apple Camera Connection kit (obvious really) and also a powered USB hub to avoid the 'device drawing too much power error.' I was wondering if this problem has been fixed with iOS 7 or not; do I Still need the USB Hub? 

So, in short, my question is: Will I need to buy a powered USB hub to connect the Blue Yeti, or can I go straight through CCK without a hub?

Edit: Another question, will there be ANY sort of recording latency using this method or the Blue Spark Digital which is the other microphone I intend to look at. It's very important there is NO lag or latency when recording into the iPad
