Since there are a lot of Traveler products, you need to access the Kingston Support page. Visit the website and then click on USB drives. Wait for the page to load and click the product you posses. If there is a driver, it will be listed on the downloads list. However, Windows doesn't require drivers for Mass Storage devices which means there is something wrong with the default driver. Plug the USB and make sure you are connected to the Internet and let Windows Update scan for correct drivers.
