I have the gpu waterblock and the pump.res xd5 and neither are lighting with the commander pro. I have the gpu plugged into the commander pro and the pump plugged into the gpu daisy chain port. I have reversed it and I have tried connecting all connections and nothing works. If it helps, I am using a internal USB hub to allow for the commander pro, lighting core (ql fans), and another device to use the only internal USB port on my MOBO (asus).
Any ideas?
