The slave connection to the esp32 can only be made through the uart serial port, the USB connection is not supported.

@lijunru-hub for the moment, i want to use USB, so i think i have to look for another solution.

It is also possible to connect via USB. You will need to use the usb_host_cdc_acm library. However, you will need to port the relevant code yourself by modifying the UART host program into a USB host program.
