Binaries and Source
You can download the Java jar-file and the shared library (Windows Dll) from the project page.
The Java and C++ source code is available at https://libusbjava.svn.sourceforge.net/svnroot/libusbjava (Subversion repository).
You will find the following three directories in the trunk folder:
- java -> the java source code
- LibusbJava -> the shared library
- libusb -> the libusb-win32 dll and kernel driver (the same as the files from the libusb-win32 project page)
