Are there any plans to increase MSC support here?

CDC+MSC may be great

Thanks

Hi all

is there any possible to switch the CDC and MSC mode in esp32-s3?
I know I can make it together but can I just use CDC mode then switch to MSC mode?

Assessment

Q Qwen · high

Both issues concern USB MSC support on ESP32-S3, but they address different specific needs. Issue #8426 is a general feature request asking if MSC support exists or is planned, potentially combined with CDC. Issue #12258 assumes MSC support exists and asks for dynamic switching between CDC and MSC modes (time-multiplexing) rather than having them active simultaneously. The candidate does not resolve the original query about whether MSC support exists or is planned; it addresses a more advanced use case (mode switching) that would only be relevant after MSC support is implemented.

Suggested action

Keep both issues open. #8426 tracks the core feature request for MSC support. #12258 tracks a related enhancement for dynamic mode switching that depends on MSC support being available.
