Hello Aqua Computer support,

I run two High Flow NEXT units, both connected to the PC by USB and configured in aquasuite. Until recently both worked correctly. After I reorganised my internal USB (I consolidated two internal USB hubs down to one, so the devices ended up on different ports), one of the two units developed a problem with RGBpx and profiles. The other, identical unit continues to work normally on the same PC and aquasuite installation.

The problem
On the affected unit, switching the active profile in aquasuite no longer updates the RGBpx lighting on the device. The aquasuite preview changes to show the new profile, but the physical LEDs stay on the previous lighting.

How I can force it to update
If I toggle the strip off and back on using the on/off control in the RGBpx menu, or even nudge the main brightness slider slightly, the selected profile is then applied correctly to the LEDs. Any manual RGBpx edit has the same effect. In other words, the device is loading the selected profile — the RGBpx output just does not refresh on a profile switch until it is forced.

What this appears to show
- Manual changes and a strip off/on toggle apply instantly, so USB communication and the RGBpx output hardware are fine.
- The forced refresh shows the correct profile, so the profile data is loading on the device; the output simply is not repainting on a switch by itself.
- If I unplug the unit's USB and reconnect it, the LEDs return to the last manually-set lighting rather than the active profile's, consistent with the output not refreshing on its own.

Already tried, with no change
- Confirmed the unit is on the latest firmware (bundled with the current aquasuite).
- Factory reset on the unit (settings exported first) and reconfigured.
- Re-saved the profiles to the device.
- Moving USB ports and restarting aquasuite / the PC.

System details
- Devices: 2 x High Flow NEXT (one affected, one working normally)
- aquasuite version: X.92
- Firmware: 1017
- Windows version: Windows 11 25H2 26200.8655
- How I switch profiles: Selecting profile in Aquasuite on the device itself or adding it to a global profile and switching it through that - it makes no difference.

My questions
Is this a known issue, and is there a way to make this unit refresh the RGBpx output automatically on a profile switch, without the manual toggle? Since the second identical unit works correctly on the same setup, this looks specific to this one device after the USB port change. I'm happy to send logs, an exported settings file, or run any diagnostic steps you suggest.

Thank you,
Polymeros

One more confirmation: the display behaves exactly like the RGBpx output. After switching profiles, nudging any display setting (toggling a screen, or changing a value and back) immediately makes the correct profile's screen appear — the same way toggling the strip forces the lighting.

So both outputs are identical: neither updates on a profile switch on its own, and both snap to the correct profile the moment they're poked. That's consistent across the two independent subsystems, which to me confirms it's the profile switch not being applied to the unit's outputs rather than anything specific to lighting or display.

This is a strange problem. I think your troubleshooting was thorough and logical. The problem does seem to the be High Flow Next (HFN). Hopefully someone from Aquacomputer will respond. In the meantime, here are a few suggestions.

1. Do a full power down and reboot. Its possible that the USB device stack is messed up. A reboot will re-initialize everything.
   
2. Open Device Manager and check if any USB device is showing an error.
   
3. Try disconnecting the working HFN and connect the problem HFN to the same USB port.
   
4. Disconnect other USB devices. Some other device may be causing a problem and the HFN issue is a symptom.
   
5. If your mobo has USB3 ports (USB3.0, 3.1, 3.2-Gen1, Gen-2 - whatever), try plugging it into one of those ports. They are probably controlled by another USB controller chip. You may need a USB2.0 5-pin female to USB Type A male connector to do this. You can buy this cable on AMAZON.
   
6. Download USB Device Tree Viewer. Its a free utility that will show a detailed tree of all USB Host Controllers, USB Hubs, and USB Devices. It also shows detailed information about every device. If a USB device is not enumerating or has a problem, it will flag it.
   
7. Download and run Nirsoft's USBDeviewutility. Its also free and displays a list of every connected USB device and a bunch of info about them. Compare what it shows for the working HFN versus the problem HFN. It may help you to narrow down the problem.
   

If you get it working, please report back what you found. It may help someone else.

Good Luck!

Thank you for your reply and suggestions. I have already tried steps 1-4.
Step 5 is quite hard to get to due to the way the computer is built, but both HFNs have been running on USB 2.0 fine.

This does not appear to be a USB issue, as the device reports fine and responds to changes with no problem. The only issue is applying the profiles, as described in the initial post. It seems like a firmware corruption to me, but I don't see a way to re-flash the same firmware through Aquasuite. Maybe someone from Aquacomputer can provide the firmware and a way to flash it.

Thank you once more for your anwer and suggestion.

Thankfully, Sven from Aqua Computer responded to my support request via email and guided me in the right direction. The culprit was Aquasuite, with some messed up settings due to the moving of the Highflow Next to a different USB port. The solution that worked for me was to disconnect the device, then Aquasuite allowed me to remove it completely, as it was now considered not existing. I then reconnected it, set it up, and profiles work fine.

Thank for your help here, I appreciate it.

I've had multiple Aqua Computer products for many years and have switched things around without issues. This time, the software glitched and it did so qhuite weirdly. Good to know and the solution is simple, once you know it.
