I just realized this is the ubuntu bug. The developer is not looking at this one. The main one, is https://bugs.launchpad.net/fingerprint-gui/+bug/745505 . anarsoul is the maintainer of the libfprint. If someone has windows, please provide sniffs. I used USBlyzer http://www.usblyzer.com/download.htm in trial for this. Javier Domingo 2013/2/7 HENRY Florian
