ESP32-S3 - turn off USB JTAG/debug unit

Postby marbalon » Fri Mar 17, 2023 9:12 am

Hi,

Is there any option to disable build-in JTAG/debug unit at startup? ESP32-S3 is acting as a custom vendor device. But when I'm plugging it appears as JTAG unit first and for a while and then switches to a new vendor device. For Windows 10 it is a bit problematic because very often Windows USB services go crazy and do not detect anything new over USB and you need to restart windows to get it working again. I found similar issues and looks like it is known but not resolved bug in windows when something is quickly changed in USB port.

I tried different fuse bit options and disabled all of the features USB related but nothing helped.
