esp32-s2 usb driver

[DitroniX]

I see in the interesting video that by "holding down GPIO 0 and powering up" (such as then inserting the USB). Changing to the ROM Bootloader to expose and allow native USB to work, is the missing link... maybe.

However, trying this on a number of ESP32-S2-WROOM's which I have just received for a project, none seem to enter this bootloader with GPIO 0 held down - Enabling the CDC-ACM device.

Guess we need to update the bootloader in esp-idf 4.2, once released?

Will continue to investigate.

This is all in the ROM bootloader; no need (or possibility even) to update this. The official way to get the device in bootloader mode is pulling GPIO0 down, then pulsing RESET down for a moment - the ESP32s2 should enumerate over USB then.

HI all, I have to windows machines that are windows 10, both can't flash via usb even though the ESP32-wroom is recognized. @Ditronix, have you found a resolve to this issue? Pulling down the IO0 pin also does not work on mine.
Thanks

Do you have any more diagnostic information than 'can't flash'? Error messages, symptoms, ...?
