Theres 2 buttons on the bottom left portion of the board. You can try pushing the right one. This worked for me and someone else here.
Really, there are so many secrets...
I pushed the right button, and all fans started running for about 10-20 seconds and then shutdown. But I still got the same error messages:
tie@rig07:~/cgminer$ ./cgminer -n
[2014-02-04 23:35:25] USB all: found 3 devices - listing known devices

If run cgminer directly, got those:

Do I need to initialize the device like I did for my GPU when doing scrypt mining? Thanks again!
