I'm new to all this IOT thing. I just received a NodeMCU V3. I tried to plug it into my pc using the usb port, but when I do this, every usb devices disconnect from Windows (Keyboard, mouse, etc.). They connect back when I disconnect the NodeMCU. I downloaded the CH340G driver and it still doesn't work.
I tried to connect it with USB to Serial converter, but it still doesn't work, either on 3.3V or 5V. I have a 5V and 3.3V volt output on my USB to serial device. The only difference is that using 5V (Vin), my USB to Serial doesn't power on, but with the 3.3V pin it does. But still, I can't see the NodeMCU in the device manager, only the usb to serial device.
I did not soldered anything to the board and nothing is plugged in. Nothing is getting hot and I'm not sure if it is supposed to have some led ont the board to light up, but nothing happen
Am I missing something or my device is defect?
Thanks for your help.
