Ahh that makes sense, well that was a waste of $15.  Silly me for not doing more research and assuming a powered hub would be fine.  No one to blame but myself.

And Rival, thanks for the link.  I am in the process of ordering 4 Anker hubs which should handle 36 badboys.  Hopefully the problems are all behind me.

But, would there be a reason as to why having 5 plugged into 5 different USB ports would not make all of them work with Windows 7?  I would think that each individual port should have enough juice to run one miner?
