Hi,
what you need to do is download the utility that configures the controller and edit the configuration, then write it back to the controller.
You need to find an "MPTool" (Mass Production Tool) or whatever your controller utility is.
The documentation is notoriously poor for this.
The Utilities are known to be targets for malware people to infect and there are other challenges.
If possible, I would like to see:
A good photo of both sides of your device.
A good photo of both sides of the PCB (the inside circuit board, you will have to open it if you can).
A report from USBDeview from Nirsoft would also be interesting.
websites that have the tools include
