Hello there, 

I have a Elitebook 9470m with Validity sensor device 138a:003d, 
looking around it seems feasible, I'm exactly in the same situation as yours. 

regards

Hi there, 

also seeking a solution for the Validity VFS451 Fingerprint Reader -- 
on a HP Probook 6540B: 

$lsusb 
Bus 001 Device 004: ID 138a:0007 Validity Sensors, Inc. VFS451 
Fingerprint Reader 

$lsb_release -a 
Description: Debian GNU/Linux 7.7 (wheezy) 

The latest driver version from HP-SuSE, for the Probook 6540B, was also 
released somewhere in the year 2011 and is an RPM build. However, I can 
no longer find that specific release or any othoer. So I've since 
contacted HP support and just awaiting some reply (URL). 

... of course I won't hold my breath on that. 

Because of my lacking of technical software engineering skills I'm 
probably not of much assistance other than what others have already done 
-- just locate the latest release of the closed source Linux binaries 
and submit a URL to the source. 

Sourcing MULTIPLE HP releases of closed source linux binaries for each 
variant of their scanner hardware may prove a mission in itself. 

I've read fprint's Project Needs(recommended reading):

Regards, 
Damon
