Ok this is just flat confusing. 

I Hanover one miner that exhibits the following symptoms

1) if it is turned on before my raspberry ip combiner doesn't see it. Then ten minutes later or so the pi will crash!!

2) if it's on after the pi, the pi crashes almost instantly

3) if I connect it to my PC and turn it on there. Then unplug the USB and plug it into my pi it runs fine for hours.

4) when "doing nothing" before crashing the miner the next to last led will be solid on. Nothing else.

* I have tried multiple pis and multiple USB hubs.

Thoughts?  Should I be using bfgminer instead?
