I want to communicate directly with a full speed CDC device from my STM32F769 running in USB host mode but I only have a high speed OTG USB port available. From example code for other STM32 devices it appears this is possible but can anyone confirm this ?
Thanks

In case anyone else has this (unusual) requirement, yes a STM32 device in high speed host mode can communicate with a full speed slave device. In my case, I have a STM32F769-EVAL board enumerating & sending data via the HS-OTG connector (ext. ULPI phy) to a PD42-3-1241 step motor driver (full speed USB device)
