Did you look for any Window's updates. If there are none of them, i'd be tempted to enter the registry and delete all keys pertaining to the device.
Sometimes if the first install goes wrong, then the registry keeps a record and if you try to install again it just uses that record over again.
If you are unsure how to do that say so and someone will walk you through it.
