Thank you David for your response but that didn't work for me.
The white light in the controller still doesn't blink and the HMD doesn't detect it. That is keeping me stucked in the first step of the configuration of the headset. It seems to me that it might be a firmware problem in the controller and, if that is the case, since there is no usb connector I guess that the only way to fix it is sending it back to the factory. :smileysad:
