What version of arduino-esp32 are you running? You are missing the option for USB mode. What you really want is to have HardwareSerial not attach anything to the USBSerial. If you look at the code , what you want is CDC boot turned off, and USB_MODE set to OTG (but not activated in code). These opt...

I have arduino-ESP32 version 3.0.7 (looks like the most recent one). I am also posting the compilation output. Isn't the USBMode the 4th from the bottom on the image I've sent earlier? FQBN: esp32:esp32:esp32s3:USBMode=default Using board 'esp32s3' from platform in folder: C:\Users\Administrator\App...

Thanks for the quick answer. I have to use these two, because all others are used for GPIOs. If it is not possible, I will need to make a PCB change :? . If I can solve it without hardware change, that would be perfect. I updated my code as you suggested, but still same behaviour. Works when plugged...

Hello everyone, I have a working code that sends MIDI messages as a USB device to the computer. Now, I also want to send MIDI over the TX pin of the ESP32-S3 C1 Dev Board via a DIN connection. My code works, and I can read the messages through a serial-to-USB cable when I connect the ESP32-S3 C1 to ...
