Hello everyone, I have
an issue connecting D5 pump motor with USB and aquabus interface to the MB.

One month ago I bought AC d5 pump with USB and aquabus interface and installed it in my system. I connected it straight to the MB through the USB interface and it worked well. But unfortunately I wasn’t able to see it in device manager and in aquasuite as well. That time I didn’t go all the way and research why it wasn’t working, and assumed that I just need a controller to make it work properly. So I ordered aquaero 6 XT.

Two weeks later I got my aquaero 6 XT delivered, so I installed it and connected it to the MB as well. Aquaero immediately showed up in device manager (as keyboard) and aquasuite, but still no trace of D5 pump anywhere.

After that I thought that maybe D5 and Aquaero should be connected through aquabus and aquaero should be connected to MB through USB, still nothing. Also, while USB cable from D5 is disconnected (from MB) , on the boot, all the watercooled components start to heat like crazy so basically the liquid is not flowing in my system or the pump rotation is too slow (can’t hear it working). So basically without USB cable, pump is not working (or working incredibly slow), but at the same time while USB is connected pump is not showing up in device manager and aquasuite.

Then I thought that maybe the problem may be with USB cables or something with pin sequence etc. so I redone all the cable management inside my case, changed USB’s from D5 to Aquero and checked if cables where connected to MB and devices properly - still nothing.

I was told that D5 should immediately show up as “MPS” in device manager after i connect it to the MB through USB cale, but unfortunately that is not my case..

Could you please help me to resolve my issue? If needed, I could provide some additional details.

I will appreciate any help!
Thanks in advance!

P.S. Here on forum, I found one possible solution,
but it didn’t work as well:

“Steps to follow if you have the same problem:
1 Connect pump only through power supply molex
2 Boot PC and uninstall Aquasuite and all unknown USB devices (Through Computer Managment - Device Manager)
3 Reboot
4 Install Aquasuite (I set to run as administrator and start on boot)
5 Complete Shutdown and Power Off (PSU Switch Off)
6 Connect USB to Pump and Motherboard
7 Boot Windows normally and the device should successfully be detected as MPS and available in Aquasuite."
