Hi there, yesterday I connected first time a ESP8266 to PlatformIO in Visual Studio For Code.
Times before, I was working withan Arduino Nano, without problems, all works fine (compiling, upload).
But yesterday with the ESP8266, I used NodeMCUV1.0 12-E as board, compiling was ok, but upload was not possible. I tried it also with Arduino IDE, there wasn’t it possible. I get following error in Arduino but in PIO was the same error:

esptool.py v3.0
Serial port COM8
A fatal esptool.py error occurred: Cannot configure port, something went wrong. Original message: PermissionError(13, ‘Ein an das System angeschlossenes Ger�t funktioniert nicht.’, None, 31)
Has someone an idea? I think the drive should be well, because wiht Arduino Nano was no problem.
Is there a problem with the esptool.py in python ??
