4. Plug in the USB cable. Windows will detect the interface and install the 2 FTDI drivers that we installed prior. This may take a few minutes to finish. When it's complete, you should receive 2 notifications on the bottom right stating the USB Serial Port and USB Serial Converter are ready to use.

Check: You can check if it was installed correctly by going to Control Panel> Device Manager and locating:
"USB Serial Port (COMX)" in the "Ports (COM & LPT)" root menu AND "USB Serial Converter" in the "Universal Serial Bus controllers" root menu
