#74382 Hello,
I have a NodeMcu v3 and it was programmed by Arduino IDE and working fine (code for Blynk and connected to wifi) but after that when I connect it back to laptop to upload a new code I couldn't see the board on any port, I mean the Node mcu didn't detected to my USB (COM port), I tried different PC and also upgrade the driver but still not detected.

Can anyone help me please.
Thanks
