Answer:
The first step to troubleshoot this issue is to ensure that the USB device is plugged in properly to the computer. Sometimes, the device may not be fully connected to the USB port, which can cause it to not function properly.
If the device is securely plugged in and still not working, then it could be that the driver is not installed properly or is not compatible with your computer. In this case, you can try to reinstall the driver or check the device's website for updated drivers that are compatible with your computer's operating system.
If still the device is not working, then you may try to connect the device to a different USB port on the computer, or try connecting it to a different computer to see if the issue is with the device or the computer.
