If you want your users to use a Digital Persona to login to a web-page using their browser, they are going to need to install a browser plugin (since neither java or javascript alone wouldn't give access in that way to the usb-ports, see How to get USB devices List from Browser).
If there is such a browser-plugin, you'd need to check it's api to see how it communicates with javascript. From there on communication to the server-side results the familiar communication options (forms, ajax, etc).
You also might attempt to create a plugin yourself, have a look at One Touch for Windows SDK Java Developer Guide for example.
You can also contact the manufacturer, since you paid for the device and are going to support it in your application.
Hope this helps!
