Hello @jding.1​  and welcome to the Community :) ,

The USB device composite is supported for STM32H735 MCU.

To implement the USB device composite, I recommend you to get inspired from available examples:

  • Ux_Host_HID_CDC_ACM: This application provides an example of Azure RTOS USBX stack usage on STM32H735G-DK. It shows how to develop a composite "USB HID CDC_ACM Host"
  • Composite_Audio_HID This application provides an example with STM32H743I-EVAL
