I've recently upgraded my motherboard from an Asus z390 to an Asus z690-E. After that, the H150i cooler and commander core would show in iCue for a brief time, and then disappear.
I've done debug logging on this, and I can see that there is a USB related error "Platform error code: 31" in the logs right around when it drops off.
I have been in touch with support, and they gave me an older firmware, which I have installed and the device was stable for 8+ hours, but it's not any use, as iCue won't let me control or monitor the cooler until I update the firmware, if I update the firmware, It's fine for 20 minutes, then disappears until reboot.
I have replicated this error on a completely fresh install of windows 10 with nothing else installed.
The pump seems to continue working running on what I must assume are default fan curves, but I bought this cooler because I want to be able to monitor the thing.
