Does the ESP32S3-WROOM-1 support USB Host?

[Jim_Stuart]

Hello, I connected my MIDI Keyboard to my ESP32-S3, but do I need a USB Host Shield to support usb hosting on the esp32s3? I ran some code on Arduino IDE to see if I can get some sort of output, but I got this instead:

Code: Select all

I'm not sure what this error message means, but I'm hoping that I can find a way to fix this issue. I read online that I might need to use a USB host shield?

You do not need a USB Host Shield for the ESP32-S3. You must ensure that your software configures the USB OTG mode correctly. I recommend starting with a simple USB host example to confirm the hardware setup. Then you can gradually integrate your MIDI keyboard functionality.
