USB CDC ACM console disappears after a software reset
Posted: Tue May 06, 2025 2:57 pm
Hello everyone,
I have successfully established a serial communication channel with an ESP32S2 module through the USB CDC ACM device. My issue is that in the event of a software reset (i.e. while reprogramming it through UART0) the usb device disappears and isn't restored until I unplug and re-plug the cable. I'm worried this hints to an underlying fragility of the connection that may come bite me while the device is in use.
Is this behaviour expected? I'm testing it with the tusb_console example.
