Looks like at some point between me leaving for work and now I dropped from 8ghash/s to a little of 5ghash/s. I'm guessing I have a port going bad on my hub or that same antminer U1 stopped working again.  If I was running as much as I have seen some run with the 49 port USB hubs or the 4 or 5 S1's I don't know if I could take it being stuck at work and not be able to see what's wrong.   Maybe its best I don't get anymore.
