FTDI Virtual COM Port Drivers installation
You have to download the drivers from FTDI website - http://www.ftdichip.com/Drivers/VCP.htm
Unzip it to your own folder.
When you connect the USB board, the following message appears: FOUND NEW HARDWARE and drives need to be installed.
The red and green LED flashes 2,3 times and turn off. When the red LED and the green LED flashes means that there is a communication between the USB relay and PC.
After the drivers' installed, an additional COM port appears in the Device Manager of Windows - usually it is COM3:
