I have a lot of questions about USBX

[arilink]

1. How does the FIFO created in MX_USB_Device_Init() match the endpoint?
2. In the USBX document of Azure, the descriptor is directly made into an array, while the sample program uses a lot of functions to implement it. What are the benefits of this? Not easy to analyze
3. ux_app_parameters_change() corresponds to CDC Control. How can I operate CDC Control to change the baud rate and other operations?
4. ux_device_class_cdc_acm_read() reads data. How to make sure it reads the correct endpoint data?
5. Initialize USBX Memory size is 32K Is this the smallest memory value? Can it be reduced
