I am confused. How can you have a Quadro connected to USB and to an Aquaero via Aquabus? I thought if you connected a Quadro or an Octo to an Aquaero via Aquabus, the fan controller becomes a slave to the Aquaero and would not longer appear as a separate device in Aquasuite. Is it OK to connect a Quadro or Octo with USB and to an Aquaero via Aquabus at the same time?
Yes you can connect both at the same time
If memory serves, having the octo/quadro aquabus connected to the aquaero, does slave the pwm ports to the aquaero. Doing so essentially excludes the fan controllers from the octo/quadro for a total of 4 controllers (aquaero only), instead of 12/8 possible controllers. (octo 8 + aquaero 4 or quadro 4 + aquaero 4)
