Cannot Detect Fingerprint Sensor on Ubuntu 12.04
 
I installed software to use fingerprint login, but when I run it, It doesn't show it.

My computer is the Lenovo B570 Laptop.

It worked on the windows 7 the computer came with, but it crashed.

Can you please put command outputs in code tags? It makes them easier to read.

I beleive this is the Sensor.
I did some research and found out that Lenovo V570 Also has the same sensor

According to ubuntuforums, people have reported this device to not have Linux drivers. This means that it is unsupported on Linux.
