Correction to the title, the machine is a panp7.
I have a brand new Pangolin (It arrived yesterday).
I followed the instructions on Knowledge76 for "How to use the Fingerprint Reader" (not how to install it), but if I use FingerprintGUI from System>Preferences, then try and scan, a dialog pops up nearly instantly telling me that it could not read the print. I tried installing fprint-demo, but it tells me that there is not device installed. Similar results come from running pam_fprint_enroll at the terminal.
Is this a permissions problem? I'd like to be able to use my reader.
EDIT: I should point out that I have installed the System76 drivers and lsusb shows the scanner, as below:
