I'm having an interesting problem. I am using my Aquaero 5 pro with a power adjust 2.

I connected the Poweradjust 2 via USB to upgrade it to v1003, I then set the power output to 65%. When I connect the Poweradjust to the Aquaero 5 Pro via high speed aquabus the fans connected to the Poweradjust DON'T spin. If I remove the aquabus connection the Poweradjust works fine and the fan spin.

Is there something I'm missing?
