Light board disconnect: serial connection closes

[Google Code Exporter]

What steps will reproduce the problem?
1. Turn cube on
2. Wait (mttf 10min)

We believe that changing the baud rate on the serial connection may fix the 
problem.

We believe that the root cause of what we were seeing was that the USB hubs do 
not have enough power to drive the arduinos when all ports are connected (they 
are not rated at full USB spec).  Based on this we reorganized so that there 
are fewer dimduinos left on each hub.  This appears to have significantly 
lessened the issue.

We saw 1 dimduino box disconnecting in a slightly different mode after this.  
We are not sure if it is related.  We replaced the arduino in the dimduino box, 
and this appeared to resolve.  We are currently in monitor mode to determine if 
the issue is completely resolved.
