USB API Details

Introduction

This page explores the USB API, a crucial component for interacting with USB devices. Understanding this API is fundamental to many applications that utilize USB connectivity.

API Overview

The USB API is a standard set of protocols and commands that define how devices can communicate over USB. It enables seamless data transfer between devices and operating systems.

Key Concepts

• Device ID: Each USB device has a unique ID for identification.
• Command Codes: Commands are used to control the device's behavior.
• Data Transfer: The API facilitates the transfer of data, like files, images, and more.

Example: Device Identifier

Let's say the device ID is 1234567890.

The API might require the following command:

device_id <1234567890> info

This command returns information about the device.

Example: Data Transfer

User can transfer a file (e.g., a JPEG image).

device_id <1234567890> transfer

The API sends the file data over the USB device.

Practical Applications

This API is extensively used in:

• File Transfer: Sharing files between computers.
• Device Management: Controlling and monitoring USB devices.
• Multimedia Applications: Streaming audio and video.
