Just installed this and I got the above message using a CLC 280. Everything is up to date. I have an Asus Strix-E Z390 MOBO, and the pump is connected to the AIO header. The usb is connected to the usb header on the mobo.

Unplug the UBS Cable count to 5 and plug it back in.
When you remove the Cable do you hear any Window Sounds?
Like when you plug in a USB Device like a Mouse or KB.

I did not hear a sound.

Are there any LED's On?
Are there any Yellow ! in your Device Manager?

No yellow in the device manager and the LED is on for the pump.

Re-check the connector on the MB that you have it set Pin 1 to Pin 1 and not backwards.
In the Bios do you have the AIO Header set to 100%?
"EVGA Flow Control Device Not Found" if your Motherboard cannot see it then the Software cannot see it.

Yes. It somehow worked right now. Will keep you updated if anything changes thank you.
