If you get an error in device manager when you connect your Arduino or FTDI cable- you may have a different chip sometimes called a CH340. Windows does not currently automatically download the drivers for this so your component is not assigned a COM port.

Download the CH340 driver here and you will be all set:…

Plug in your Arduino, FTDI cable, or other micro controller and run the exe. That’s it! This problem seems to common on what people call the “Arduino clones” and “clone boards” but it actually has nothing to do with the source or board- it is purely the serial communication chip used. Easy fix!
