Pluggable Authentication Modules

[Grizzly]

Hi All

Has anyone tried using a USB (pamusb-tools) to authenticate in Xenial (16.04) ?
and how did it go

I tried on Trusty 

Installed pamusb-tools libpam-usb
Added USB device to PAM configuration
Checked /etc/pamusb.conf for entry
Defined a user for PAM authentication
Checked /etc/pamusb.conf again
Configured PAM to use pam_usb library
edited /etc/pam.d/common-auth

but never got it to lock/unlock if USB was unpluged/pluged
