USB Host on ESP32-S3

[abouillot]

Hi,

I have a ESP32-S3-USB-OTG devkit. I'm trying to figure out if USB Host is natively supported by arduino-esp32, or through other mechanisms.

I noticed several blog posts, youtube video talking about this feature, but all seems to rely to espidf rather than arduino itself. In the USB part of the Arduino-ESP32 code, I notice USB, USBHID, but this doesn't seem to include USB OTG feature.

Can someone confirm the proper way, and if there is any objective to have this merged in Arduino side ?

Thanks

A way may be searching Github / Google for Arduino USB Host llibraries.
Those are the 3 that I have found:
https://github.com/tanakamasayuki/EspUsbHost - USB HOST for HID Mouse and Keyboard
https://github.com/esp-arduino-libs/ESP32_USB_Stream - USB HOST for UVC + UAC (multimedia ~ Camera, Mic, Speaker)
https://github.com/sauloverissimo/ESP32_Host_MIDI - USB HOST for MIDI

Another Alternative is the Adafruit TinyUSB Library that works fine with the ESP32-S3.
USB Host Examples can be found in https://github.com/hathach/tinyusb/tree/master/examples/host

Another way to go would be by creating an Arduino as IDF Component project that has the Arduino Sketch and the IDF USB Host Component all together.

Using the IDF Examples Code, it may be possible to build some API on top of it that can also be used with ESP32 Arduino Code.
