USB connection between ST Micro Connect box and PC

For USB port connections, plug the USB cable into the USB port of the ST Micro Connect 
box (as shown in 

Figure 9

) and connect the other end into the PC’s USB port. Once the 

ST Micro Connect box is connected and powered-on for the first time, your PC will 
automatically look for a USB device driver.
