Bitfury never supported my writing the software and wouldn't even sell me hardware - so it wasn't until someone sent me a BlackArrowBitfury board that I could write and test a driver for it.

The detection code and work send command is almost the same logic as chainminer - just less bugs
If they've updated the code and not released (i.e. don't want anyone to support their hardware) then yeah my code won't know about the updates
https://github.com/bfsb/chainminer is their code as far as I know ...
