Now that I'm able to look at everything, bfgminer is just showing 4 of them running.  I think I know what one is no longer working.  I only see one with out a flashing green light.

EDIT:  I just moved it to a port on the hub and put a different one in its spot and all 5 are working again.  Not sure why it went out or how that even fixed it.  The hub is sitting in a spot where it hasn't been moved or touched for weeks now.
