Jwar, I tried as you said and everything works great but the problem is:
I am using 8 corsair hd fans and commander pro of course but I have lighting node pro as well which requires another port for LED's.
I have one corsair hd fan hub connected on my commander pro but then the second port I have my lighting node pro leds connected so there is no way where to add another fan hub to commander pro.
for power I fixed the problem but for leds I am missing one port.
I have 8 corsair hd fans and 4 lighting node pro led strips. I have all the hubs and commander pro but just not enough ports.
No idea how to connect all of them...
