Are you using a real JVM/JRE or gcj? I don't think anyone has tried gcj, although it would be great to get it working...
Specifically it appears that you don't have "javax.usb.UsbDevice" in your CLASSPATH; that is part of the API pacakge. I'm not sure how CLASSPATHs work with gcj, I honestly have very little experience using it, although I'd like to try it out...
