Comment 24 for bug 790183

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
