I followed different tutorials to enable fingerprints reading, but without luck.

Fingerprint GUI keeps saying no device found.

Any help on this?

= Edit Following first answer =

I followed the tutorial you posted to install the fingerprint

the result of lsusb is :

Okay I'm running a Thinkpad X1 and the same biometric chip is on it. I searched the whole internets twice for this problem, but, good news, I found a way to make it work in all cases, so here's a small "tutorial" that compiles the info from this thread and other places:

Installing the software

First, add the fingerprint PPA as mentioned by the previous posts, and install the required packages:

sudo add-apt-repository ppa:fingerprint/fingerprint-gui

sudo apt-get update

sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui

Then, download and untar this http://volker.de/wp-content/uploads/2012/12/BSAPI_4.3.291Lite_SDK_for_Linux.tar.gz.

Modifying libbsapi

Libbsapi's PPA currently does not really support this chipset, however, replacing the install's with the latest version will work. First, figure out you architecture (32 or 64), and then locate the libbsapi.so file in either the lib folder (for 32 bit) or the lib64 folder (for 64 bit). Then, copy this file (using sudo, or gksudo on nautilus) to the /usr/lib folder.

Then, we have to make an addition to this file: /lib/udev/rules.d/40-libbsapi.rules . The code do be added is:

#Added for Upek 2020 support

ATTRS{idVendor}==”147e”, ATTRS{idProduct}==”2020″,   SYMLINK+=”input/touchchip-%k”, MODE=”0664″, GROUP=”plugdev”

ATTRS{idVendor}==”147e”, ATTRS{idProduct}==”2020″,   ATTR{power/control}==”*”, ATTR{power/control}=”auto”

Do it using either : sudo nano /lib/udev/rules.d/40-libbsapi.rules or sudo gedit /lib/udev/rules.d/40-libbsapi.rules, whichever you might prefer.

Last modification and it's all done

We have to grant fingerprint-gui access to the reader's USB bus. Run lsusb and locate the line that may look like this Bus 001 Device 003: ID 147e:2020 Upek (actually look for the 147e:2020 Upek ID). 001 here indicates its bus id, and 003 is its Device id. Note yours. Then, issue the command (in my case, but adapt to your own bus and device id's):

sudo chmod 666 /dev/bus/usb/001/003

Then, start fingerprint-gui, and it should recognize your device, and configure it happily.
