Distinguish USB mouses from USB multiplier

I want to distinguish a very simple Java program to distinguish two mouse connected in USB multiplier. I will connect two mouses to USB multiplier, and the program you'll develop should print a line of text: - "Mouse 1 clicked" when I click on mouse 1 - "Mouse 2 clicked" when I click on mouse 2 with JOptionPane. that's all. BUT, PLEASE GIVE ME A BID IF YOU KNOW THE SOLUTION, DONT REQUEST IF YOU WILL SEARCH THE SOLUTION. I got 1 day(about 22,5 hours) for this job, and I need completely working Java desktop application with clear sourcecode Thanks
