make sure your hub is not USB 3.0 as that causes problems with miners...

USB3 have been ok for me. I just make sure they go through a USB2 hub before connecting to a USB2 port on the host.
Edit:- To clarify the above.
1. Place miner stick in USB3 "powered hub"
2. connect cable into USB2 "un-powered hub"
3. connect this usb to your USB2 port on PC
4. With a PI "Forget the above" and look for a USB2 "Powered Hub"
