It maps libusb functions to object-oriented interfaces\u2014for example, libusb_init becomes USBContext, and libusb_get_device_list becomes a context method returning USBDevice instances\u2014while converting C error codes into Python exceptions.\n\nThe 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.","worth_installing":"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."},"id":"libusb1","links":{"html":"https://skillfed.io/packages/libusb1","md":"https://skillfed.io/packages/libusb1.md","pypi":"https://pypi.org/project/libusb1/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-16","license_spdx":"LGPL-2.1-or-later","license_treatment":"copyleft","name":"libusb1","python_support":"unspecified","summary":"Pure-python wrapper for libusb-1.0"},"popularity":{"monthly_downloads":618950,"position":5731,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"3.4.0"}
