That is interesting... Is your Windows install up-to-date? As far as I'm aware, Windows 10 should automatically see the device as a CDC device and install the proper driver. (You probably still will see another unsupported device, this is the DFU device and unfortunately we do not have drivers for that at this point in time.)

Having now populated some prototype designs using the ESP32-S2-WROOM, all display the same issue with lack of Windows 10 driver, and on different PCs.

This occurs when going into programming mode ready for flashing via USB.

Did anyone find a resolve for this please?

Many thanks
Dave

Hi DitroniX,

you should be able install WinUSB driver for ESP32-S2 with https://zadig.akeo.ie/. However, flashing via USB is not yet supported by ESP-IDF.

Many thanks for this feedback. Will investigate and also await updated ESP-IDF in due course.

We played a bit with the USB interface of the ESP32-S2 in ROM bootloader mode.

Indeed you should get automatically a serial COM: (on windows) for the CDC-ACM.
In addition the chip in bootmode also exposes a DFU interface (see in the video). That needs probably a driver on windows. In OS X or linux you can access it via a generic usb library.

This is interesting and thanks for the video link. Look forward to an update to allow the native USB to work.
