ESP32-S2 2nd usb-serial port
port-esp32
HI
At micropython for ESP32-S2, I'd like to have
secondary USB-serial port (like /dev/ttyACM1 on linux)
which directly maps to board's hardware serial port
RX/TX pins and if possible, few RS232 signaling lines.
Can this (easily) be done?

ESP32: two USB devices
port-esp32
The latest nightly creates two USB devices - /dev/tty.SLAB_USBtoUART & /dev/tty.usbserial-01A7EA3E. A few weeks ago there was only SLAB_USBtoUART (on Macos).
At least AFAIK. I only noticed this because Pymakr now gets confused and tries to connect through usbserial-01A7EA3E which doesn't work (which is a problem of Pymakr not uPy). Updating the firmware through SLAB_USBtoUART does work though.
