Hi, I am having difficulties with monitoring/changing fan speed with the QUADRO, because it does not appear in Aquasuite. I am using an external MORA-3 radiator (using Noctua NF-A20 PWM x4), and am using the following Aqua Computer parts:

[1] D5 NEXT (pump)
[2] High Flow NEXT (flow sensor)
[3] QUADRO (fan controller)
[4] HUBBY7 (internal USB hub)

My main issue: QUADRO does not appear in Aquasuite, but the D5 NEXT and High Flow NEXT do. I'm unable to monitor/change fan speed. The fans are spinning at a constant, low RPM.

If you look at this first picture (https://imgur.com/5XRoQ9W), the D5 NEXT has a sub-section with Pump, Fan, RGBpx, etc. The High Flow NEXT similarly has Sensors, RGBPx, Alarms, etc. However there is no such section for the Quadro. Is the Quadro supposed to have a similar sub-section also?

Furthermore, in this second picture showing all possible data sources (https://imgur.com/lcJ9Q4m), the QUADRO again does not appear, although the D5 NEXT and High Flow NEXT do.

Question: How do I get the QUADRO to appear in Aquasuite? How do I change fan speeds? (Is there user-error, or is there a defective item? Should the Aqua Computer items be connected differently?)

Thanks in advance for any advice.

------

Other information (I'm 99% certain these are connected correctly, but want to provide you with this information in case):

Power:
D5 NEXT: SATA power cable connected to SFX power supply
High Flow NEXT: mini USB cable connected to HUBBY7
Quadro: MOLEX power cable connected to SFX power supply
Hubby7: mini USB cable connected to motherboard's USB 2.0 header. Jumper is set to USB, not SATA.

All mini USB cables are plugged in with correct orientation, i.e. red wire vs. black/ground wire

Status Lights:
Quadro: Behaves as manual describes - blinking for first several seconds upon power-on, then light turns off
Hubby7: Lights up when power is on.

Cable connections:
Noctua fans x 4 to 4-way Fan splitter by Watercool to QUADRO, all using 4-pin PWM cables
D5 NEXT to Hubby 7 (port 1), using mini USB cable
QUADRO to HUBBY7 (port 4), using mini USB cable
High Flow NEXT to HUBBY7 (port 6), using mini USB cable
HUBBY7 to motherboard's USB 2.0 header

Misc:
I can create an overview page, and import the file "quadro.page", please see this screenshot (https://imgur.com/PRqODPZ). However, (1) the Quadro still does not appear below with settings I can change (as opposed to the D% NEXT and high flow NEXT), and (2) I can't configure any of the sensors because the Quadro does not appear in the list of data sources (as seen in the second image).

Quoted from "InfoSeeker"

Check if your USB connector at port 4 on the hubby 7 is properly centered
The sockets for ports 2,3,4,5,6 & 7 are wide enough to allow the connector to be shifted left or right by one pin.

That was exactly it: connector was off by one pin. This was a "dumb" mistake on my part, but tight spaces/poor visibility of the sockets (near ground, under table, shadows, couldn't get closeup view, etc.) was a big contributing factor.

Thanks so much to both of you for taking the time to help out!
