ESP32-S2 no connect to PC-USB , ESP8266 is ok?

Hello
I’m currently trying to install new firmware on two of my ESP32-S2-Saola-1 boards via the USB port with ESPhome-connect.

Unfortunately it can’t find the USB port.
What’s strange is that when I attach my D1 mini boards or other ESP8266 dev kit boards to the USB port on the PC, ESPhome-connect finds these ports.

I have already tried installing various drivers from the China website. without success.
Both ESP32-S2 boards are not found

What am I doing wrong?

edit
my PC-System is a new WIN-11

There are different types of usb controllers, each requiring different drivers. Check what chip is used and make sure you installed the driver for it.

Install the drivers from a reliable source.

What serial chip do the boards have? They are likely near the usb port.

It is a cp2102. Make sure you install a driver for cp2102.

They are made by silicon labs. Download the driver here, not some screwy unreliable Chinese site

Or install Linux and get all the relevant drivers in the OS. (I can’t believe windows don’t include these drivers)

PS you may need to uninstall the random drivers you installed.
