Received mine today they are hashing but with horrible error rates 58%+ and only hashing at 2.3GH

For now I would recommend everyone use cgminer or our version of bfgminer 3.0.99 until we fix it. I have been communicating with Luke and we are working out the issues.

switched to your specific Raspbian Wheezy Setup Bfgminer build and still only getting 2.3GH

Look like these are performing 20% lower than spec.

I'm running only two of them in a D-Link Hi-Speed USB 2.0 7-Port Powered Hub (DUB-H7) and 1 raspberry Pi as controller

I am running a single BF, on Win7 per the instructions in https://bitcointalk.org/index.php?topic=319419.0. With bfgminer ver 3.2.0 and the recommended batch file (bfgminer.exe -S "BF1:all" -o ...) it runs without H errors, but with the same lower hash rate that you are getting (about 2.26 GH/sec).... Huh

I am currently doing some testing. Running it on Ubuntu on a vm. I am getting 50-100mhs more on our version if bfgminer. The usbs are hashing at a speed of 2.5-2.8 for me. I would highly recommend Ubuntu virtual machine until we can get windows problems fixed.
