Sorry to reopen an old thread, but I stumbled into an issue after doing the modifications suggested by this post.
This work perfectly well for the USB connection, but I had to remove also two extra resistors (R21-R22) to disconnect the CP210 from U0TXD and U0RXD. Before doing that I was able to send data over UART from the ESP, but I wasn't receiving anything on U0RXD.

Hi, as ESP_Sprite has indicated, I have rotated the position of the resistors 90°. However, my PC (Windows) does not detect any USB device now. Is it true that no additional driver is required?
I would be also interested in knowing if there is any guide for configuring the VS Code platform in this case. Thanks in advance.

Your Windows machine should at least show the USB-serial device in Device Manager, and in normal circumstances you should also get a COM port out of the deal without any need for drivers.

I believe in VSCode you simply select USB-serial-JTAG as the programming method and JTAG method in the IDF extension; support for it is built in.
