Hello

I want that my STM32 has two usb descriptors. For example: If I plugin my STM32 Microcontroller to a pc, the pc should

recognize

the STM32 as two USB Devices. (For example as Camera and as Microphone Device).

Is this possible?

best regards

Yes, that would be a composite device. Like all USB devices it will have only one device descriptor, but the interfaces can belong to different classes and be controlled by different drivers on the host computer.
