Hi Tomek,
Just a update from Espressif: probably ESP32-C5 will have USB OTG, but
since it was not released yet we cannot confirm it (things can change
before releasing the chip).
They suggested that companies interested on get this information
should ask directly to the business support: sa...@es
Maybe OTG is superseded? USB C dual role port is the way to go, but needs a 25c
chip and software support to make it work. FUSB30x FTW :)

Well all ESP32-C3 boards that I have (DevKit, M5) have UART-to-USB
converter so no JTAG so far.. I will order Beetle ESP32-C3 this one
should have direct USB/UART/JTAG pins on the USB-C connector :-)
I have ordered ESP32-S2 as it has USB OTG. I really miss RISC-V MCU
with USB Device/OTG.. ESP32-C6
