The easiest way to do it would be to use the built-in Bluetooth (wireless) connection. However, if all you have is USB (assuming it connects to your phone), then you should just have to attach the phone to your computer. The computer should recognize the peripheral and ask you what you want to do. If you have something like Picasa or another image viewer attached, you can import the files to that program. Otherwise, you should be able to open the picture folder on the phone and copy the files to your computer.
