ESP32-S2 Arduino UART1 & USB problem

Hello i got 2 problems:

1) UART1, how do i defined the pin? i believe default GPIO18 = UART1RX and GPIO17 = UART1TX, but i can't seems to get it working with HardwareSerial or just simply calling Serial1... also how do i remap UART1's pins?

2) i use the USB example, to create USBCDC in arduino, but i can't get my pc/host to detect the USB serial connection

I think you need to install this driver. And compile your code with CDC enabled.

No, it is already compiled in arduino-esp32.

This example requires to connect pins 19/20 (D+/D-) to USB port. You can cut regular USB cable.
