I'm working on a project in which I would use another MCU to burn program onto STM32 MCU over USB, but I can't find USB bus timings anywhere. That other MCU will also have other functions. When powered on it should check sd-card for the binary file and if it's present, it will burn it onto STM32. The idea is here, now I only need USB timing diagrams to accomplish it.
Any help would be appreciated.

STM32 DFU Application Note AN3156
USB timings? Wouldn't that be dictated by the bus standard itself?
AN2606 might describe the system loader expectations for the specific "STM32" in question.
Perhaps also look a Linux USB DFU drivers for ST parts.

Yes, that is actually what I needed to get started. Thanks a bunch.
