To get this working on linux, I needed
   usb4java-1.0.0.jar
   jsr80-1.0.1.jar

To get this working in MS Windows 7, I installed the JDK, then eclipse,
then I created an empty Java application project,
then I did
   - right-click on the root of the tree in the panel on the left side of Eclipse
   - Project/Properties/Java Build Path/Libraries/Add JARs
   and added both jar files (usb4java-1.0.0.jar , jsr80-1.0.1.jar)
Used Zadig to replace all the Windows drivers for the Cintiq devices.

No need to reboot.
