I have a Thinkpad X1 Carbon. I followed these instructions, but to no avail.

The output of lsusb is:

sguha@ajgubi:~$ lsusb

I tried everything what can be found via google but my fingerprint device is not even listed in lsusb. Could someone confirm that working solution exists for Lenovo X1 Carbon 3448-2D9 running ubuntu 13.10? –  biera Apr 15 at 22:41

I can confirm, that finger printer works perfectly on Thinkpad X1 Carbon Touch using fingerprint-gui (http://wiki.ubuntuusers.de/Fingerprint-GUI) and the experimental libssapi (https://launchpad.net/~fingerprint/+archive/fingerprint-gui-experimental).

Why not try the instructions from here? (Disclaimer: haven't tried myself, but might do so if i find the time...)

The fingerprint reader on your device should be

Bus 001 Device 003: ID 147e:2020 Upek

The instructions you linked to work just fine on my X1 Carbon 3460-2D3 running Kubuntu 13.04. I could scan and successfully verify prints over the Upek device at 147e:2020. However, I couldn't put it to much use due to the kdm and kscreensaver bugs.
