Might be a issue with my clock source setup. Used a 74f04 hex inverter IC to get the crystal oscillating. Might have the wrong capacitance on the crystal. but My block erupter likes to run with a 16 mhz crystal installed and a active mini fan cooling system changed the voltage resistors to 1.2k
Hashing is all over the place between 390-500 mh/s  Im wondering if this is my cgminer settings? sometimes the status led stays on for a bit of time as though it is waiting for work.
