Got my new powered hub (Plugable® USB 2.0 7-Port Charging Hub) for my Raspberry Pi Bitcoin mining. Works perfectly!
ThePiHut's HUB hub simply didn't have enough Amperage to give each ASIC miner plugged the power it wanted.
I'm running a mix of miners that I found cheap on eBay which I thought might be an issue but cgminer seems to be handling them fine.
Hopefully when I have some more funds I can start looking at renewable energy sources as currently the power draw, even on a Raspberry Pi doesn't seem economical for the gains. For the moment i'm not in it for that, just for the fun of experimenting!
