Hi all I've faced with next defect: https://bugs.launchpad.net/ubuntu/+source/fprint-demo/+bug/850232
But I've found a workaround: 1. Add to /etc/rc.local file next commamnd: :~$ chgrp -R plugdev /dev/bus/usb/ 2. Add your user to plugdev group by executing next command :~$ sudo usermod -a -G plugdev $USER And one more if you already used fprint_demo under root privileges (:~$ sudo fprint_demo), change ~/.fprint/ folder owner: :~$ sudo chown -R $USER ~/.fprint/ :~$ Sudo chgrp -R $USER ~/.fprint/ or just remove folder ~./fprint (DO NOT REMOVE IT IF YOU ALREADY CREATED YOUR FINGER PRINTS AND DON'T WANT TO LOSE THEM) :~$ sudo rm -r ~/.fprintcopy/ Start fprint_demo without sudo :~$ fprint_demo Regards -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/790183 Title: [138a:0011] Fingerprint reader Validity Sensors not recognized To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libfprint/+bug/790183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
