USB

These samples demonstrate the use of USB support in Zephyr RTOS.

Most of the USB support samples can be found under samples/subsys/usb in the Zephyr project tree. However, there are a few functions whose samples are located in different directories. These are:

• Bluetooth HCI USB transport layer implementation is covered by HCI USB

• USB CDC ECM and USB CDC NCM implementations are covered by the networking samples zperf: Network Traffic Generator or HTTP Server

• Console over USB CDC ACMOutput "Hello World!" to the console over USB CDC ACM.
• USB Audio asynchronous explicit feedback sampleUSB Audio 2 explicit feedback sample playing audio on I2S.
• USB Audio asynchronous implicit feedback sampleUSB Audio 2 implicit feedback sample playing stereo and recording mono audio on I2S interface.
• USB CDC ACM UART sampleUse USB CDC ACM UART driver to implement a serial port echo.
• USB CDC-ACM bridgeUse USB CDC-ACM driver to implement a serial port bridge.
• USB device testing applicationTest USB device drivers using a loopback function.
• USB DFUImplement a basic USB DFU device
• USB HID keyboardImplement a basic HID keyboard device.
• USB HID mouseImplement a basic HID mouse device.
• USB Mass StorageExpose board's RAM or FLASH as a USB disk using USB Mass Storage driver.
• USB MIDI2 deviceImplements a simple USB MIDI loopback and keyboard device.
• USB shellUse shell commands to interact with USB device stack.
• USB Video webcamSend video frames over USB.
• WebUSBReceive and echo data from a web page using WebUSB API.
