If it is an unknown device, then it’s probably that you needs to install the driver

- Plug PLC
If nothing happens, check if the led of the PLC blinks. If not, check the power supply or maybe the power of your USB port

- Some (usually cheap) USB cables may work with some devices, but not all – due to the diameter of the USB cable wires
Try on another PC
