I had fingerprint-gui set up and working nicely, used it for login and authenticating root stuff. Now suddenly it stopped working. It does not show the "Enroll your finger" prompt.
I reinstalled fingerprint-gui and it does not recognize my fingerprint reader. It just shows "No devices found". But in the menu underneath it shows " Upek (0x147e) Biometric Touchstrip / Touchstrip Fingerprint Sensor (0x1002) "
I don't understand because until now it was running just fine.
Ubuntu 12.04, Unity
UPDATE: WORKS NOW - Probably after an update
