Hmm I guess it is the hub, I just connected the one I thought was broken directly to my computer and it was working. So whats causing my raspberry to not receive work. Four of them were receiving work when connected to my windows desktop.  When connected to my raspberry pi it doesn't get any work when its receiving jobs from  btcguild and one erupter gets work when its receiving jobs from slush's pool. Is that still the hubs fault?
