Try this:
cgminer.exe --bmsc-options 115200:0.65 -o xxx -u xxx --bmsc-voltage 0800 --bmsc-freq 1306
That's it! Mining at 60GH on a raspberry pi.
Thanx mate!
Ok, I blew up my power supply

If you like this setting don't try it with the original power supply. Now using an XBOX supply. 14A is that enough?
