This issue is still active. I just installed a 360mm rad in my brand new 3800x build, with a brand new x570 motherboard, and starting this morning Ive been getting this error, and Ive noticed it disconnects and reconnects usb often. I have verified the connectors are properly seated, the software is installed properly, and I never use hibernation or sleep. I was able to make the error go away by uninstalling and reinstalling, but already Ive noticed it do the connect disconnect thing.
Heres the thing, its a brand new computer and no other USBs are having issues. Granted, the CLC cooler plugs into a mobo header, but all my other headers work fine as do my USB ports.
My major question / concern is how important is it even to have the USB plugged in. I know thats how we get PWM control, but how differently does it function if you dont have it plugged in? The instructions expressly say you can do that but they recommend plugging it in.
