Not sure if I understand. I clicked on factory default for the mps and didn't do anything. I also did it for the aquaero. Shut down pc..unplugged it for 60secs. started it back up same as was before. The D5 is connected to aquaero via aquabus. Do I need to connect it to the usb header also to get this to work again?
reset all mps devices (with usb connection) to factory defaults, and set up ist new and give each device an individual aquabus address.
After changing some aquabus depend settings you have to power down/up your system.
