How to determine what controller came in SOF?

Create a project in CubeMX for TrueStudio, class usbaudio full speed. Device (stm32f103c8t6) is defined in Windows shows that sound is playing. Tell me, is there in generirovanie CubeMx project the code that is triggered by the arrival of the SOF? If so, how to generate your event on the arrival of SOF?
