OK! Now it works with bfgminer !! Had to use the
32Bit Version! NOT the 64Bit ....

Don't use bfgminer with blades or cubes. You'll lose a pretty significant amount of hashrate.
It's not that bad! Runs from 9-12 GH/s. Runs on a win7 64Bit Atom System.
Only Thing: bfgminer was shut down this morning after +/- 4 hour running :-(
Now I have a Programm installed, who checks on the task.
If it shuts down again, it starts bfgminer automaticly ... ;-)
Hope this works.
