## What it is
A Node.js library for communicating with USB devices, built on libusb with prebuilt native bindings. Development has moved to node-usb-rs since v3.0.0, so this library is in maintenance mode.

## Use cases
- communicate with usb devices from node.js
- read and write to a usb peripheral in javascript
- list connected usb devices and their vendor/product ids
- send control and bulk transfers to a usb device
- build a node.js app that talks to custom usb hardware

## When to choose
- you need low-level USB access from Node.js on Linux, macOS, or Windows
- you want prebuilt native bindings without compiling libusb yourself
- your device uses the default configuration and non-isochronous transfers

## When to avoid
- you need isochronous transfers or non-default USB configurations
- you're starting a new project - development has moved to node-usb-rs
- you need a pure-JavaScript solution without native modules

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, developer-tools, embedded
- domain: hardware, developer-tools, cross-platform
- platform: cross-platform, windows
- tags: usb, libusb, hardware-access, native-module, typescript, nodejs, linux, macos
