There are known problems with bfgminer, the zeus chips (fury) and some pools.
I have never seen an explanation for the reason behind the issue ... but if you use a compatible version of cgminer they seem to work on all pools.
I have two GAW Fury. I use a Linux version of cgminer (3.1.1) that's compatible with Zeus chips. Seems like everything out there is for Windows, I had to do a bit of searching to find a Linux version.
I run several Zeusminers.... I use Raspberry Pi, running Minepeon 0.2.4.6 and I compiled cgminer 4.3.5 from here... works perfectly:

I'd like to get some more ASIC, but don't want to pay the electricity costs. I switched to those two Furies (and stopped using two Radeon 7850 GPUs) and my electric bill went down $20 per month. I don't want it creeping back up. I'm cheap!!
