Python binding for the libusb C library.

Project description


Python binding for the libusb C library.


Python libusb module is a low-level binding for libusb C library.
It is an effort to allow python programs full access to the API implemented and provided by the well known *libusb* library.

PyPI record.


libusb is a lightweight Python package, based on the ctypes library.
It is fully compliant implementation of the original C libusb 1.0 API by implementing whole its functionality in a clean Python instead of C.

libusb API 1.0 documentation can be found at:
libusb-1.0 API Reference

libusb uses the underlying libusb C shared library as specified in libusb.cfg (included libusb-X.X.* is the default), but there is also ability to specify it programmatically by one of the following ways:

import libusb
libusb.config(LIBUSB="libusb C shared library absolute path")
# or
libusb.config(LIBUSB=None)  # included libusb-X.X.* will be used

libusb - A cross-platform user library to access USB devices


libusb is a C library that provides generic access to USB devices. It is intended to be used by developers to facilitate the production of applications that communicate with USB hardware.

It is portable: Using a single cross-platform API, it provides access to USB devices on Linux, OS X, Windows, Android, OpenBSD, etc.

It is user-mode: No special privilege or elevation is required for the application to communicate with a device.

It is version-agnostic: All versions of the USB protocol, from 1.0 to 3.1 (latest), are supported.

What platforms are supported?

Linux, OS X, Windows, Windows CE, Android, OpenBSD/NetBSD, Haiku.

For additional information, please consult the FAQ or the Wiki.


  • It is a fully independent package.
    All necessary things are installed during the normal installation process.
  • ATTENTION: currently works and tested only for Windows.



To install run:

python -m pip install --upgrade libusb



  • Development is strictly based on tox. To install it run:

    python -m pip install --upgrade tox
