Developers // Micrium OS // Micrium USB Device

USB Device

USB is an incredibly user-friendly protocol, but there is often a substantial amount of complex software needed to enable its plug-and-play operation. For a product intended to connect to a USB host (in many cases, a PC), this software usually includes a USB device stack. Micrium OS features a robust yet efficient USB device stack that can streamline the development of your next USB-enabled product.

  1. Overview

USB Host Highlights

 USB 2.0 stack supporting full-speed (12 Mbit/s) and high-speed (480 Mbit/s) devices

 Support for composite devices

 Device suspend and resume support for reduced power consumption

 Test cases and test harness for verifying stack integration

 Infrastructure for development of vendor-defined classes

Class Implementations

USB Devices Classes

Classes   Example Device Type
Communications Device Class Abstract Control Model (CDC ACM)   Emulation of a virtual serial port on the host PC. Communication with the device via serial terminal or native serial communication APIs
Communications Device Class Ethernet Emulation Model (CDC EEM)   Ethernet networking over USB. Micrium OS TCP/IP compatibility
Human Interface Device (HID)   Support for devices such as mice and keyboards.
Mass Storage Class (MSC)   Support for storage media from the host PC. Compatible with Micrium OS file system
Vendor Class   Facilitates the development of devices that don't adhere to the requirements of existing classes.

Stack Compliance

Micrium uses the USB Command Verifier (USBCV) to validate the compliance of the stack with the USB specification. The USBCV is the official compliance test tool for USB devices. This tool is provided by the USB Implementers Forum (USB-IF). The USBCV offers a test suite to validate the compliance of a device with Chapter 9 of the USB specification Revision 2.0 (enumeration process). It also offers a test suite for several classes.

The following table lists the different layers of Micrium USB Device and the USBCV test suite used to validate the implementation.

Layer   USBCV Test Suite
Core   Chapter 9 Tests
Human Interface Device Class   HID Tests
Mass Storage Class   MSC Tests
Device Controller Driver   Chapter 9, HID, MSC, PDHC Tests
