switched to your specific Raspbian Wheezy Setup Bfgminer build and still only getting 2.3GH
Look like these are performing 20% lower than spec.
Can you please try minepeon 0.2.4 on your raspberry pi. Arch is a lot better then raspbian. Also how is it connected up is it directly connected to the raspi?
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 tried minepeon 0.2.4 and that's where i was getting the 60% error rates on bfgminer, could not get them to even recognize on cgminer under minepeon 0.2.4.
