I have bought today a NodeMCU v2 (I think). I am a simple 17 year-old high-schooler who wants to learn some things; I don't know a whole lot...
I connected my NodeMCU to my laptop with a microUSB to USB cable, the same one that I use to transfer photos from my phone to my laptop. The laptop simply does not show me the NodeMCU while connected (I am running Windows 8 for reference). It makes the little sound when I plug it in (also a small blue light flashes once) or out and the Wi-Fi AI-THINKER_2CD750 appears in the Wi-Fi tab.
It doesn't try to install the drivers or anything, nothing happens. I tried to install the drivers myself from the github page, that did not work either, it says that they are preinstalled. Please help my poor soul.
It happened to me too. For me The board was bad. After replacing with new one it was working with same drivers
