libusb: A Cross-Platform USB Device Access Library
libusb is a free, cross-platform library designed to allow user-space applications to access USB devices. It simplifies the process of communicating with USB hardware from your own software.
Project Introduction
Summary
libusb is a library for software developers to communicate with USB devices. It provides a generic API that is independent of the operating system, simplifying the development of USB-aware applications.
Problem Solved
Directly accessing USB devices from user-space applications is complex and highly operating-system dependent. libusb abstracts away these complexities, providing a simple and portable interface.
Core Features
Cross-Platform Compatibility
Provides a consistent API across multiple operating systems (Linux, macOS, Windows, BSDs), allowing developers to write portable USB applications.
Comprehensive Transfer Support
Supports various USB transfer types including Control, Bulk, Interrupt, and Isochronous transfers, enabling communication with a wide range of devices.
Device Discovery and Access
Enables searching for, opening, and claiming interfaces on connected USB devices directly from user space.
Tech Stack
Use Cases
libusb can be used in various applications where direct interaction with USB devices is required from user space:
Custom Hardware Communication
Details
Writing software to communicate with and control custom USB hardware devices.
User Value
Allows interaction with prototype or specialized USB devices without developing complex kernel drivers.
Firmware Programming Tools
Details
Developing tools for flashing firmware onto USB-connected microcontrollers or devices.
User Value
Provides the low-level access needed to send firmware binaries and control device bootloaders.
USB Device Diagnostics
Details
Creating diagnostic or testing applications for USB devices.
User Value
Enables reading device descriptors, sending control requests, and monitoring data transfers for debugging and analysis.
