Java Separate input of two separate keyboards

I have two USB keyboards connected to the same machine. I am developing a Java application. Is there anyway to let the Java application separate the USB keyboard from this? (For example, there is something like http://docs.oracle.com/javase/6/docs/api/java/awt/event/KeyEvent.html , but with a USB parameter so that I can find out which USB- devices did he come?)

Thank!
