Confirm installation of Intel® Edison Drivers

Connect a micro-USB cable to the device mode micro-USB port of the Intel® Edison expansion board, and the other end to your computer.

If you see both “Intel Edison USB Composite Device” and “Intel Edison Virtual Com Port” items show up in Device Manager under “Ports (COM & LPT)”, the drivers have been successfully installed.
