I can confirm that the hub works in led channel 2 with all 6 fans connected and lit up, i can connect the 7th fan into the led hub if I unplug one of the other fans and it will light up, so not the fan, i even tried plugging the second led hub with the last (7th) fan into the node with no luck. i have node plugged into the usb on the commander pro for led strips which all work fine. not sure where to go from here
