When I type in the commandline: lsusb -s 001:003 -v I get this information:

Because it couldn't open device 003:ID 06cb:0081 Synaptics,Inc. on bus 001 of course fingerprint won't work at all.

Normally one should type the next commaands in sequence:

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

Solution?

It seems that some device is deactivated by BIOS Setup

see dmesg | grep -i tpm


Setup BIOS to enable 'Security Chip', and the fingerprint sensor device in 'Security' section and in 'I/O ports' section.


With my (old) Lenovo Thinkpad i had to edit the bios setup from 3 distinctive section areas.
