usb4java is a Java library to access USB devices. The low-level part is based on the native libusb 0.1 shared library and reflects this API as complete as possible. Java NIO buffers are used for data exchange between libusb and Java. The high-level part implements the javax.usb standard (JSR-80).
Supported platforms are Linux (x86 32/64 bit), Mac OS X (x86 32/64 bit, PowerPC 32 bit) and Windows (x86 32/64 bit). But other platforms may work as well (as long as they have Java 6 and are supported by libusb) by compiling the JNI library manually.
For Windows the libusb port of the libusb-win32 project is used and you need to create and install a driver for the USB device you want to use with usb4java (Instructions can be found on the libusb-win32 website).
Warning! usb4java is a brand-new project and is not well tested. The low-level API will most likely work as expected because it simply wraps a stable native API but the javax.usb based high-level API is a complicated piece of software and may contain many bugs. But to squish them I need testers so please give it a try and give me feedback or send me patches: k@ailis.de
