This library is a fork of libusb-win32.
The design objective of this library is to provide a better out-of-the-box experience for AVRDUDE Windows users.
This library only supports a subset of the original implementation. The intend is not to provide a general purpose implementation, but to satisfy the usage scenarios of AVRDUDE.
This library supports only Microsoft Visual C/C++, as used in the msvc job of the AVRDUDE build action.
The latest version of libusb for Windows can be found here:
https://github.com/avrdudes/libusb
The original README of libusb can be found here: README.
This library was completely rewritten to support the default Windows WinUSB driver, as well as the legacy libusb0.sys driver, while maintaining a libusb-0.1 compatible programming API.
