Hello, I have the same Problem. My computer (Win 10) is not recognizing the Arduino. It is very strange. When I connect the VIN and GND to a powersupply, but do not turn on the power, the arduino is recognized in windows.This is very strange.Can anybody help me with that Thank you.Mike
I double checked it with several cables. So this can not be the problem. So you think I have a "faulty" Arduino regarding to soldering issues?
I checked it aigain. --> It only works when I connect VIN and GND (on the Arduino) directly. Very strange.
Did you take it out from ESD foam and put to bread board. ESD foam can pulldown reset so it's in reset.
Yep, i lay it out over a non conductive surface (plastic). Moreover I tryed to manually set the board in the bootloader double pressing the reset button, but also in that case nothing is showing on w10 device manager, the only COM port present is "Intel(R) Active Management Technology - SOL (COM3)"
When double press reset bib the red led start to do fading?
Edit:Do you have any unknown or other device in device manager?
