Icarus Detect Failed
This sounds like a power problem to your erupters most likely. Can you show me the config file or the options you are enabling? In particular, the -scan option.

Further, you might verify you have a powered USB hub and try using a powered USB port if available; it only takes a little power to run them, but a little power to stop them. I also power my rasp pi through a wall charger also, rather than powering it from the usb hub.

I have had much more success running BFGMiner with Erupters and Antminer U1 USB sticks with a Pi and usb hub to control (and using Minepeon on the rasp pi). The command to start BFGMiner and scan for erupters etc and create a log in case you do have problems is: 

bfgminer –o [pool] –u [user] –p [password] –scan-serial erupter:all –icarus-options 115200:1:1 –icarus-timing 3.0=100 2&gt;logfile.txt
