Just noticed that ckolivas commited a changeset a few hours ago with an update to the bitfury driver. Re-compiling from source, with those changes, made a difference in the numbers I was seeing in cgminer. Cgminer reported hash rate went from around 1.7-1.8Gh/s to around 2.2 - 2.5Gh/s.

I didn't think the changes would make such a difference, but there will be hardware errors reported now.

Anyway in case someone cares, here's an updated windows binary with the changes:

Seems to be helping my numbers a bit, on two different ubuntu boxes. Recompiling now on a beagle-board xm... will post results after a soak in.

Well that looks quite significant then. It's probably a minor USB change I made to the code rather than a change to the bitfury driver itself.
