I have this hub on order from ebay.co.uk seller orico_pc:
ORICO 10-Port Aluminium USB3.0 Powered HubOrdered on 2013-07-16, before I'd done more research to know that USB3 may have problems with cgminer / Rasp Pi. I'll let you know if it works with MinePeon.
PI and USB3 hubs don't work... Its USB 2 only with the Pi and you need to buy a decent one... None of those 10 port $6 on eBay jobs.
