BFGMiner's been giving me issues lately, i've had that happen UNTIL it submits a share... but it's definitly at least 1 share per ant per min so it should show some hash rate...

Been working on an erupter and its now got issues, think I blew the buffer on it as it's acting that way now, the ant is a direct connect so that isn't likely.  If you have a USB camera you could use as a form of microscope ( I managed to find a used one for 10 bux used since they didn't know to pull the cap off the end ) it's darn handy for looking at those SMD parts.  It might be as simple as pull off the heat sink and the pad, put in a toaster oven for 4 min at 200 F and let cool before reaplying the pad then thermal paste then the heat sink.  BTW there are 2 green LEDs at the top corner, they both flash on found shares, lower one flashes on work done, no share.

Edited to add the following
i think my eyes were playing tricks on me, in the dark I only see 1 green flash..... but the other one looked like it flashed.... so which one flashes on the deadish one?
