I have my unit running with the prebuilt windows version.
I have it over clocked to 275mhz and the resulting hash rate reported by CGM is about 2.18ghs WU27.1/m.
 
I am seeing a high error rate (around 10%).
Strange thing is I seem to get this error rate no matter what clock rate I have tried.

IMO the drivers from AntMan on the github for cgminer works, but it needs some tweaking.  I shipped a unit to a developer who works on a few of the builds for CG and BFG miner software for his input.  BTCjoe sent this over to get multiples working - here's his trick:

With CGminer is running, add one in and then use Zadig to reinstall the driver for the one you just added.   You kind of have to keep an eye on which one just popped up in the drop down list of Zadig because it doesn't really tell you which one is the new one you just plugged in.

While CGminer is still running, after you reinstall the driver with Zadig, pull it out for a few seconds and plug it back in.. and CGminer will find it and run it..

I'll take 10.  BTC coming your way.

Dying in a week? Do you realize it's the most requested feature on cryptsy?
