A little help would be appreciated here ;-)

Hello Ijust finished building my WC-PC everything works fine, except i'm having the exact same problem here Connect USB: Aquasuite recognises MPS D5 but no control RPM is always 100 according to software and i can slide the speedcontrol but pump keeps at full speed. Connect Aquaero 5LT: Pump get recognised again adress 12 under currently connected. Tryed 13 too. But same story, no control. I tryed everything in this topic too. I hope there is a solution?
