Trouble getting java file to run

I'm a beginner to Java Programming and I'm having a little trouble getting this file to run. I'm pretty sure the main problem lies in the "import" statement at the top. ` // MotorTest.java // Andrew Davison, ad@fivedots.coe.psu.ac.th, October 2011

/* Class for opening and closing the Kinect Sensor's motor USB info from http://ift.tt/13ZoMGw */

import java.io.; import ch.ntb.usb.;

public class MotorTest { private static final short VENDOR_ID = (short)0x045e; private static final short PRODUCT_ID = (short)0x02b0; // the IDs were obtained by looking at the kinect motor using USBDeview

public static void main(String[] args) {

// find the device using the vendor and product IDs
Device dev = USB.getDevice(VENDOR_ID, PRODUCT_ID);
if (dev == null) {
  System.out.println("Device not found");
  System.exit(1);
}

System.out.println("Opening device");
try {
  dev.open(1, 0, -1); 
  // open device with configuration 1, interface 0 and no alt interface
  System.out.println("Opened device");
}
catch (USBException e) {
  System.out.println(e);
  System.exit(1);
}

System.out.println("Closing device");
try {
  if (dev != null)
    dev.close();
}
catch (USBException e) {
  System.out.println(e);
}

} // end of main()

} // end of MotorTest class`

When I try to run the program, I get this:

MotorTest.java:10: error: package ch.ntb.usb does not exist import ch.ntb.usb.*; ^ MotorTest.java:24: error: cannot find symbol Device dev = USB.getDevice(VENDOR_ID, PRODUCT_ID); ^ symbol: class Device location: class MotorTest MotorTest.java:24: error: cannot find symbol Device dev = USB.getDevice(VENDOR_ID, PRODUCT_ID); ^ symbol: variable USB location: class MotorTest MotorTest.java:36: error: cannot find symbol catch (USBException e) { ^ symbol: class USBException location: class MotorTest MotorTest.java:46: error: cannot find symbol catch (USBException e) { ^ symbol: class USBException location: class MotorTest

The ch.ntb.usb is a jar file. Am I not connecting that file to the program in the right way? Any input is appreciated!
