Description

Uploading a sketch over usb otg should reset the chip after upload, but it does not.

Other Steps to Reproduce

• Select USB mode = USB-OTG, USB CDC on boot = enabled, Upload mode = USB OTG CDC.
• Upload sketch
• Board correctly resets into download mode using 1200 baud and uploads the sketch
• Board does not reset and run the sketch as it should, instead staying in download mode. Here you have to press the reset button manually. On S2 the board resets and runs the sketch after upload with no manual intervention.

Tested on s3 devkitc and all UnexpectedMaker s3 boards.

Notes:

• No esptool commands reset the board, on the s2 it does reset
• Esptool doesn't detect when the board was put into bootloader using IO0 as it does on s2 (WARNING: ESP32-S2FNR2 chip was placed into download mode using GPIO0)
• USB mode and upload mode set to hardware CDC resets as expected
