Hi everyone,

Is it possible to use the USB port for both JTAG and Mass Storage Devices (or CDC)?

This can either be

It enumerates as a composite device
For the first 10 seconds of booting it’s JTAG, but also switches over to MSD if nothing has connected

I’m using the ESP32-S3-Mini and I am using every pin, so I can not use the external JTAG interface.

Thank You
