title: NodeMCU Devkit not recognized by pc , unable to upload code
body: <p>I was given the nodemcu devkit v0.9 with code on it already uploaded using Arduino IDE, I have been trying to upload to this again but the Board would appear in device manager but then I would try to upload using arduino IDE and receive , com error.</p>
  
  <p>I have tried different usb cables, different ports , and now there is simply a blue light on steady when the board is plugged into usb. The user button no longer turns on the small blue light , and my comp does not recognize the board being plugged in our out at all.</p>
