USB-C Connectivity and COM Port Issue with KC868-A4S Relay Controller

[Bhumijo]

Hello,
I am facing an issue with my KC868-A4S relay controller. When I connect the device to a PC via a USB-C cable, the PC does not recognize it. The red light on the device turns on when powered, but there’s no indication that the USB-C connection is active, and the COM port does not appear.
Here are the steps I’ve tried so far:

1. Tested with 3-4 different Type-C data cables but still couldn't detect the COM port on the PC.
   
2. Installed the USB driver from this link before attempting the connection.
   

I’ve attached a photo showing the device powered on with the red light picture  .
Could you please guide me on how to resolve this issue? Additionally, if the device itself is not working, is there a way to verify whether the hardware is functioning correctly or an alternative method to test it?
Looking forward to your suggestions.
Thank you!

USB-C cable whether connect to computer directly? not by USB-HUB? i suggest you use another computer for a testing.
