libusb1
Pure-python wrapper for libusb-1.0
Decision gist · record as of 2026-08-14
Yes, if you need USB device access from Python and can install libusb-1.0 on your target OS. The package is actively maintained, has no known vulnerabilities, installs with low friction, and provides a clean Python API to libusb. The LGPL-2.1-or-later license is permissive for most use cases but requires disclosure if you distribute the library; check your project's licensing constraints. Windows users must handle driver setup separately.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires libusb-1.0 system library installed and accessible to ctypes; on Windows, driver setup (WinUSB or libusbk) needed per device; CPython 3.6+ or PyPy 2.0+ required.
- Low friction installation; pure Python wheel with no compiled dependencies.
- Active maintenance with last commit on 2026-05-16 and release within 90 days.

What it is and what it does
libusb1 is a pure-Python ctypes-based wrapper around the libusb-1.0 C library, exposing USB device enumeration, configuration, and data transfer operations as Python classes and methods. It maps libusb functions to object-oriented interfaces—for example, libusb_init becomes USBContext, and libusb_get_device_list becomes a context method returning USBDevice instances—while converting C error codes into Python exceptions.
The package supports both synchronous blocking I/O and asynchronous event-driven transfers with callbacks, allowing developers to build USB applications on GNU/Linux, Windows, OSX, FreeBSD, and OpenBSD without writing C code. It handles the complexity of device claiming, interface selection, and transfer lifecycle management, though users must still install the appropriate system libusb library and, on Windows, configure device drivers separately.
Use it for
- Read sensor data or control hardware devices connected via USB in embedded or IoT applications.
- Build cross-platform USB diagnostic or firmware-flashing tools without rewriting logic per OS.
- Implement high-throughput data acquisition from USB instruments using asynchronous transfer batching.
- Enumerate and interact with multiple USB devices in a single Python process for device management utilities.
- Prototype USB communication logic in Python before optimizing performance-critical paths in C.
