Implementation example stm32l452 USB AUDIO Device class

Hello

I am struggling on how to init the USB device so that it recognized as a USB Audio device .

How do I transmit data.

How do I link the structures for device class properties

If I use CUBE Mx the generated code only gives an init.

The Audio Device class exmple is on STM32l476RG here it is implemented under the macro .

USB_OTG_MODE_DEVICE

stm32l452 generates under macro USB.

I need some guidance please help.
