If you are experiencing this issue with the RGB lighting on the pump this could be an issue with the USB connection. Please try these troubleshooting steps to further narrow down this issue.
-
Go into Control Panel and click on "View Devices and Printers" then remove the NZXT USB Device/Unknown USB Device and restart your PC. Then check CAM again. If you still see an Unknown USB Device, then it seems that the USB cable is creating a bad connection to the motherboard. You can try using a different USB cable to check and see if the USB cable that came with the package is faulty. You can use a mini to regular USB cable and route it to the back of your case to test this issue. If the cable is the issue, please let me know.
-
Try shutting off your PC, then plug the USB cable to a different USB header on your motherboard. This is to check if the USB port on the motherboard is working correctly.
If the above steps do not work you can request for new cables to be sent to you to see if this helps fix the issue. Please submit a ticket by going to the following link https://www.nzxt.com/customer-support
