Hello. This device is reported to have an invalid code at byte 18 (0x13), and throws an unhandled error because of it -- By default, libfprint chooses upektc_img driver for this. Something I notice in the code is that all of the UPEK drivers seem to be hardcoded for SWIPE, as where this device is actually an "Area" or PRESS device. It also seems that the expected image dimensions (144x386) from libfprint are different than the dimensions that the device actually has (256x360), which leads me to believe that the incorrect driver for this device is being selected by default.

Hi,

I believe UPEK re-used USB IDs for another device. I have 147e:2016 and it's actually a swipe device.

Is it a standalone USB device or it's another embedded into some laptop?

Standalone

And where I can purchase it?

This model has actually been "rebranded" to the device I have, so it's a different model number. I've contacted our vendors to find out the original model number for you, that'll probably take a couple of days.

This page says it's no longer manufactured:

http://www.neurotechnology.com/fingerprint-scanner-digitalpersona-eikontouch-710.html seems to be the same exact device (specifications), not sure if it's protocol is the same.

As a matter of fact, I do see 710 being the recognized device model, even though our vendors mentioned otherwise -- I suppose it's just a successor of the same model.
