[fprint] Driver for Upek Eikon Touch 510?

Hi list,

I would like to start by thanking you for libfprint and the fprint_demo.
I've been using fprint_demo for little biometrics-related exercises in
teaching for a couple of years, and it is a great tool to quickly
demonstrate how captured images look like, and what kind of minituae are

I recently switched institutions and bought new fingerprint scanners, an
U.are.U 4500 optical scanner and a Upek Eikon touch 510. The 4500 works
nicely out of the box, but the Upek touch doesn't. I would like to ask
whether there is a known solution for the 510. The 510 is area-based
capacitive as far as I can tell. The Upek Eikon touch 310 was working
nicely the last time I used it. Both look visually very similar, so I
was hoping drivers would not be an issue.

I get the following info on dmesg when connecting the scanner:

usb 1-6: New USB device found, idVendor=147e, idProduct=2016
usb 1-6: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-6: Product: Biometric Coprocessor
usb 1-6: Manufacturer: UPEK

With the default libfprint from Ubuntu 14.04 (20080303git-ubuntu), the
UPEKE2 driver is loaded in fprint-demo. As far as I can tell, UPEKE2 is
line-based, so the driver is probably incorrect.

I took the latest libfprint git and disabled the UPEKE2 driver. In that
case, the upektc_img is loaded (sometimes referred to as upekts_img).
With that driver, an image is scanned, but it looks garbled. My guess it
that it is still assuming the device is line-based (from a brief look
into the code).

Can anyone give me some pointers towards getting the 510 working?
