The problem is that nothing see's any device plugged into a usb port.
I tried all the driver and port analyzer I can find on the net. I have tried four different computers with four different os. I have tried two different USB A to micro-a cables. I have tried two different ESP8266 LUL NodeMCU V3 boards by LoLin from AliExpress. The board are marked to use CH340G drivers.
The operating system are various versions of Windows and various versions of linux.
Yes, I have tried different ports on these machine.
NO, never exposed to more than 3.3v. The main power to the board is via the USB connector, and the onboard regulator is putting out 3.3v.
I have a whole string of IoT project to do and I can't get over the first step.
Thanks for any help.
