Dear Sir
Could you locate the controller (LEDFanBox) in the 'Devices' section of Windows Settings? If not, there might be an issue with the daisy chain controller. Please provide details on how your controllers are connected in the chain.
You can also send the software log to our team for checking the TT RGB PLUS status. Please follow the steps provided below the download link.
