I finished commissioning my new rig with a full dual rad waterloop with a commander pro for fans/temps/pump control.
I also had some issues shortly after with a message about the last device plugged was not recognised, and looking at device manager, there was a continual HID device toggling with a warning symbol.
In the end I unplugged all USB devices (including the commander pro), rebooted, waited until I was at the login screen and just connected mouse/keyboard (both logitech if that mattered!), then logged in windows, and checked USB devices in device manager, no issues, so shutdown, connected just the commander pro, rebooted, logged back in, no usb issues, so left it a while, used iCUE, no issues!
I then plugged everything else back in one at a time and let each enumerate before adding the next, and it's been OK (touch wood) ever since. I can't swear to it, but I think with so many USB devices plugged in, I don't know if the commander pro was struggling to install it's USB drivers correctly.
I read around and decided to not plug my HX1000i psu's usb cable into the commander pro, but used another motherboard USB header, and also had no issues so far!
Not sure if it helps, the only hiccup I've had with a lot of tinkering over the weekend was I had to uninstall/re-install iCUE because FAN1 was stuck at 450RPM, no control over the speed, but with a re-install it's all working again. I did make countless profiles and was messing with temperature sensors (I have 2 directly in my water loop, and using two of the supplied corsair ones) so I might let that one slide..
