The Java libusb wrapper is known to work on Linux, Windows and Mac, but should work on every operating system which supports libusb and Java.
This software has originally been developed by members of the Computer Science Laboratory at the University of Applied Sciences of Technology NTB, Buchs, Switzerland.
The main project page is http://libusbjava.sourceforge.net.
This version is distributed together with the Java API of the ZTEX EZ-USB SDK and bases on the SVN version of Apr. 6, 2009. It is extended by the ability to load the (OS dependent) libraries form system ressource (e.g. in the current .jar file), see the LibLoader Class.
LibusbJava.java is the JNI class to the libusbJava.so and LibusbJava.dll, respectively. Every class starting with Usb_ represents a descriptor of the bus structure which is retrieved by calling LibusbJava.usb_get_busses().
