ESP32S3 no connection error

Other Hardware 3rd Party Boards
1

I get this error Using a ESP32S3 newly installed board:
A serial exception error occurred: Write timeout
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.
For troubleshooting steps visit: Troubleshooting - ESP32 - — esptool.py latest documentation
Failed uploading: uploading error: exit status 1

I installed the CP210x Universal Windows Driver
but I still get the error.
If I connect a Seeedrino Xiao everything works OK.
What can I do to correct the problem with the ESP?

What happens when you follow the troubleshooting steps that are linked to?

I already did all the steps in Bootloader Won’t Respond, to no avail. I've worked on this for a day and even reinstalled the Ardunio IDE... Nothing.

Did you try re-installing the ESP firmware? Are you sure you are putting the ESP in an upload state? Sometimes you have to toggle some pins in the right order to do that...

Generally, more detail about what you did, and what happened, would be helpful... more "blow by blow" and less of an overview.

Thanks for your help! I found the solution; I disabled, then enabled the com port, and now it works.
Thanks again!

What do you mean? i have kinda the same problem but i can't understand how to fix it or why it happens. Even because on my PC it works like perfect, but in my laptop it doesn't work

Start the Upload; when you see "Connecting...", hold down the IO0/Boot button for 1 second or so and release. Should be a Go from there.
