[0138a:01]Validity Sensors, Inc second swipe doesn't work

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm this issue occurs on my HP Pavilion dv6 laptop:

Same problem on a Dell Vostro 5480 with reader 138a:0011 Validity Sensors, Inc. VFS5011

But the problem does not occur on fprint_demo. I posted a message to fingerprint-gui about this:

http://home.ullrich-online.cc/fingerprint/Forum/topic.php?TopicId=519&Posts=0

Here's a copy of I what I observed and posted to the fingerprint-gui forum

==================================

Hi, I just got a Dell Vostro 5480 with a fresh Ubuntu 14.04 pre-installed by Dell. Tried to use Fingerprint-GUI, but cannot enroll. First enroll works, and all the others fail. My reader is:

Bus 002 Device 014: ID 138a:0011 Validity Sensors, Inc. VFS5011 Fingerprint Reader

I searched the Internet and found 5 or 6 similar posts on several forums, all with no solution.

Here's the details:

Install:

sudo add-apt-repository ppa:fingerprint/fingerprint-gui
apt-get update
apt-get upgrade
sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui

Logged off and logged in

From a terminal, I tried:

fingerprint-gui

or

fingerprint-gui debug

The reader is detect, and I can select the finger. When I go to the Scan/Verify tab, it says "Please swipe Your Right Index"

I swipe the finger and it shows OK with a green check and asks for a second scan, but no more scans work.

Rafael,

This bug remains on Ubuntu 16.04? I want to buy this same model but now I'm afraid.
