Re: Block Erupter Prisma (>=1.4 T/device, 0.75-0.78 W/G, <1 BTC/T, October Shipping)
I compile cgminer for raspberry pi
try both
https://github.com/ckolivas/cgminer
https://github.com/blockerupter/cgminer
can only get 1T speed
use their controller can get 1.4-1.5T speed
compile is quite easy
i just git clone https://github.com/ckolivas/cgminer.git
and cd cgminer
./autogen.sh
./configure --enable-blockerupter
sudo make
i try ckolivas's 4.7.1 , 4.7.0, and blockerupter's (which is 4.6.1), no luck, only 1T speed

It seems like one of your boards isn't hashing. Make sure all your boards are connected and the power supply cables are snapped in.
Yes, you are half right
i'm along with AM's guy testing it, confirmed it's a firmware related bug(can be fix with a cgminer update, and not affect every units), sometimes boards #0 #1 #2 #3 recognized as #1 #2 #3 #4, so only #1 #2 #3 is woking, lost 1/4 hashrate.
When its happens, cgminer will show tons of error like this: BET0: Unexpected value 00 received
AM's guy are fixing it, stay turned
