Luke,
I'm using BFGminer to proxy a Dragon 1T miner & it seems to be working well except for the reported speed. The miner as well as the pool are reporting roughly 1TH while BFGminer is reporting 11.xx Gh. Kinda like the decimal is
two places to far to the left ...
I've heard Dragon miners are broken and require you to set the share difficulty on the device itself.
For BFGMiner's stratum proxy, the correct value is pdiff 1.
