Sorry new here, posted in wrong place.
The blue leds are around the fan, the fan and the lights are both working though.
So its not the Pi or the Pi usb port, just plugged in a newpac and set it going, hashing no problem. So has to be something on the 909
thanks all
Okay, so just your fan is running, well, bad news: the fan always runs. Maybe cgminer just crashed?
Try restarting cgminer and posting an image of what's on screen.
