Fedora 18 Not Detecting Lenovo X230 Fingerprint Reader

I have a Lenovo X230 and am running Fedora 18. I have a Fingerprint reader on this machine which I use successfully during boot up. I would like to use this capability in unlocking my screen. I have libfprint, fingerprint-gui, etc. installed. I have it checked in Authentication app to engable fingerprint reader support. When I run lsusb, I see the device:

mswallow-> lsusb
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub

Bus 001 Device 003: ID 147e:2020 Upek TouchChip Fingerprint Coprocessor (WBF advanced mode)
Bus 001 Device 005: ID 04f2:b2ea Chicony Electronics Co., Ltd Integrated Camera [ThinkPad]

but when I run fingerprint-gui, it says there's no device. This statement seems to say the support is in libfprint:

The upekts driver supports devices based on the UPEK TouchStrip chipset. These devices were originally engineered and manufactured by SGS Thomson Microelectronics but they split the business and formed UPEK in 2004. upekts is part of libfprint and is developed/maintained by Daniel Drake.

So how do I get this device activated? Any ideas?
