Ok I wanted to share my experience with this miner cause I'm getting a little crazy but I finally think I have it under control.

At first I want to put some complains about the instability of this miner. It can/will guarantee crash after running for a while.

My setup is a raspberry pi with a raspian image. At first I had my miner hooked up without any additional things. This way it crashed every, let us say, 24 hours.

I've build myself a relay that can be controlled with an arduino like board and controlled it to my server (a home pc running linux)
When I have no response in the pool for about 1 minute my server will automatically reset the relay with a power surge of 10 seconds.

I also connected a tinny display to monitor cgminer as it was running (this was my biggest mistake)

My setup worked very well only the board was now resetting every 10 minutes.
This would mean that my miner running at 63GHash was crashing every 8 minutes. This gave ma an average of 43Ghash
After several days of browsing and surfing I found that it was my tiny display that was taking to much current.

If you want to run a miner from a raspberry pi be sure that nothing else is connected to the raspberry pi. Only the miner!!!

Now my setup is working 100% and I finally hope I can enjoy the fun of mining :p

ps: The error I recieved if anyone is searching for it was LIBUSB_ERROR_TIMEOUT and I saw my device disappearing in the /var/log/syslog
