HP pavilion dv2519tu vista driver and software help

Hi!
My uncle not happy with vista that came with my HP pavlion dv2519tu, installed XP in it.
Now that I have installed vista again I am having trouble with drivers and software.

I succeeded in installing almost everything but my webcam and the fingerprint reader.

I got the drivers for the webcam and fingerprint reader and installed them.

But how do i use it?
I mean using the fingerprint reader for login security and the cam for normal pic shots?
I came to know abt the security suite for this? and I tried to get some version of it for another model of it.

The HP site has no software for this in the driver section.

Help!!!

Thanks in advance.
