Java Programming

Hi i am new in this forum and my english is not the best (i am sorry G)

My OS is: Ubuntu
IDE: Eclipse

I added the three jsr80 jar files into my Project Build File and imported the javax.usb.properties file

I wanted to test this Code

import java.util.Properties;
import javax.usb.UsbException;
import javax.usb.UsbHostManager;
import javax.usb.UsbHub;
import javax.usb.UsbServices;
public class usb {
	public usb() {	
		UsbServices services;
		try {
			services = UsbHostManager.getUsbServices();
			UsbHub vroothub = services.getRootUsbHub();
			String s=vroothub.toString();
			System.out.println(s);
		} catch (SecurityException e) {
			e.printStackTrace();
		} catch (UsbException e) {
			e.printStackTrace();
		}
				
	}
	public static void main(String[] args) {
		usb obj=new usb();
	}
}

//I copied it from this forum - thx to the User who writes it first **G*

I get the Errors:
