integrated finger print scanner

recently I purchased a new laptop ( which happened to have a built-in fingerprint scanner

I am simply trying to get this device to work.

I attempted to find the relevant lines using
sudo lshw
, but I was unable to find anything pertaining to this device

I installed everything I found with these tutorials/scripts:

I ran
sudo /opt/bioapi/bin/mod_install -i
as noted in this post:

I used distro-specific instructions where available (I'm running an ubuntu 9.04 based distro, crunchbang, so I used the ubuntu directions)

after all of this, when I run
sudo /opt/bioapi/bin/Sample
I get the following output:

Starting Sample Application
Major=1 Minor=10
BSP Index= 0
BSP Name:
Description: BioAPI v1.1 Dummy BSP

Module ID: {ffffffffffffffffffffffffffffffff}

a user name, I have tried real ones as well as fake ones, both give same output

again, I have used real passwords and fake ones for testing     
Failed to Enroll--Good Bye
I don't know what I need to do for this (I ran the script with no switches)

it seems to recognise the device, under the dummy and basic testing output.

I have heard there also exists a GUI sample application built on the bioapi framework (which I'm pretty certain is now properly installed), however I was unable to find a download for this (The file is supposedly called QSample)

if anyone could help me get this working, it would be appreciated, as long as I have it, it might as well work.

also, I don't want to use this for authentication, I'm not installing pam or configuring gdm for this or anything. fingerprints can easily be obtained from the keyboard above the reader, it is a hassle and poor security, I won't use this for authentication.

What I would like is basically just to be able to scan, see that scan, and check two scans against one another (one would presumably be saved on the hard drive), however I want this as an app, not for login.
