Can ESP32-S3 Read STM32 VCOM Over USB? #2350

|
I’ve been wondering about something and thought I’d bring it to the community for some insights. Is it possible to use an ESP32-S3 as a USB Host to communicate with an STM32 that provides a USB CDC (VCOM) port? I know the ESP32-S3 supports USB OTG, and theoretically, it should be able to handle this, but I’m curious if anyone has explored this use case. Has anyone tried using the ESP32-S3 to read/write data over USB CDC from a virtual COM port exposed by another MCU (like an STM32)? Would love to hear your thoughts, experiences, or if you know of any existing projects or examples that do something similar! Thanks for entertaining my curiosity! |

Like you said, the hardware is capable of doing that. There is currently no pure-Rust USB host implementation I'm aware of (maybe someone is working on it) |
