usb4java is a Java library to access USB devices. It is based on the native libusb 1.0 library and uses Java NIO buffers for data exchange between libusb and Java. usb4java also supports the javax-usb standard (JSR-80) through the usb4java-javax extension.
Supported platforms are Linux (x86 32/64 bit, ARM 32/64 bit), OS X (x86 64 bit) and Windows (x86 32/64 bit). But other platforms may work as well (as long as they have at least Java 6 and are supported by libusb) by compiling the JNI library manually.
When you are using Maven then you can add the necessary dependencies like this:
<-- For using just usb4java without javax-usb -->
<dependencies>
<dependency>
<groupId>org.usb4java</groupId>
<artifactId>usb4java</artifactId>
<version>1.3.0</version>
</dependency>
</dependencies>
<-- For using usb4java with javax-usb -->
<dependencies>
<dependency>
<groupId>org.usb4java</groupId>
<artifactId>usb4java-javax</artifactId>
<version>1.3.0</version>
</dependency>
</dependencies>
