Hello, I have a Thinkpad T430 with this chip. I tried to develop a driver for it but i stoped becouse the communication between the pc and the chip is encrypted. After some initial message (like "Ciao") the chip (i think) sends to pc a random message and the pc crypts this message and repost it to the chip. The message is different whenever the communication is opened. The easier solution is to develop a intermediate layer between libfprint and the proprietary library....
