thanks for your help. Now my AES3400 works.
I used functions
r = fp_dev_img_capture(capture_device, 0, &img);
r = fpi_img_to_print_data( (struct fp_img_dev *) &capture_device /* ugly 
hack ;pp */,img,&enrolled_print);
to enroll image and
r = fpi_img_compare_print_data_to_gallery(data, gal, tolerance, &n);
to verify it. Could you default export those functions default?
I found how to do contionous scanning on my aes3400( { 0x81, 0x05 } ),
but if this register isn't cleaned after scanning reader doesn't stop 
sending scans and usb buffer overflows
so I have to reopen device. Is it possible in this library to write 
register and flush usb buffer after scanning?
I also  attach my driver, could you add it to the library?

sorry for wasting your time again, but I completely have no idea what to 
do next.
I copied AES3500 and changed only DATA_BUFLEN.
My AES3400 driver scans one image correctly, but hangs on second one.
Length of last USB packet with image data is exactly equal my 
DATA_BUFLEN ( 0x208d ).
This packet contains image and all registers sent by device( last 
register in this packet, i checked it in documentation ).
I do not close the device - driver doesn't send anything after scanning.
When I perform next scan, library hangs after writing:
sync:debug [fp_enroll_finger_img] aes3400 will handle enroll stage 1/4.
I have no idea what my driver does wrong. Have anyone usblogs from 
working aes-like devices continously scanning?

Now my AES3400 scans images so I'm trying to enroll but program hangs.
When I scan image by function fp_dev_img_capture in example img_capture.c I can scan images without reopening device.
But when I scan image to enroll with function fp_enroll_finger_img it scans image first time( with result FP_ENROLL_PASS ) and when I call it second time without reopening device my program hands on scanning.
How is it possible that scanning works when I scan to capture but hangs when I scan to enroll?

I'm trying to add aes3400 support, but I get pale image(example in 
attachment) and enroll fails.
Have you any idea which parameters should I scale to improve image quality?

VFS5011 driver

Hello guys!

My thinkpad's fingerprint reader is not supported by libfprint, but I just discovered there is a "fork" to support it (actually, the only change is the inclusion of a driver!).

Is there any (good) reason why this driver is not included in the main project?

Thanks for your time and keep up the good work!

The example code doesn't works

Hi people, can you help me?

I followed the steps below:

$ git clone git://anongit.freedesktop.org/libfprint/libfprint
$ ./autogen.sh
(output: http://pastebin.com/x2pwthyT)
$ ./configure
(output: http://pastebin.com/7T3ZjHfu)
$ make
(output: http://pastebin.com/zfMLLjFm)
$ sudo make install
(output: http://pastebin.com/7py4fnbQ)

So, I opened the examples folder and ran the 'make' command
(output: http://pastebin.com/c7nnX7cU)

Then I plugged the device and ran the command

$ ./enroll
(output: http://pastebin.com/JP3Vh383)
(image generated: http://www.4shared.com/file/w88s8dVb/enrolled.html)

Then I tested with the Microsoft Fingerprint Reader and output:

(output: http://pastebin.com/7bT1Ma60)
(image generated: http://www.4shared.com/file/byuhPj8C/enrolled_microsoft_.html)

What's happening? In version 0.0.6 works the Microsoft Fingerprint Reader

Thanks (Sorry my english)

Multiple fingers

Hey all,

I'm writing a simple application for my front door, and would like to register many people.. however, the current API seems to only allow one person with 10 fingers.

Is there an easy way to just 'keep registering fingers' and upon verifying just check if there is a match in the database? I really do not care about which finger etc, just if this is a familiar finger :-)

Thanks in advance!

DigitalPersona UareU 4500

	i have finally bought one unit of this model to test it.

I am testing using fingerprint-gui right now, later i will need to
integrate with my own software.

It works but verification seems to work much better in windows with the
u.are.u SDK.

Fingerprint-gui read my finger only one time to enroll it, in windows i
have to do 4 corrects readings to enroll one finger.

My finger doesn't work very well with libfprint (fail to verify half of
the times), but works every time using u.are.u SDK.

From what i can read here
http://www.freedesktop.org/wiki/Software/fprint/libfprint/uru4000/ it
seems that the matching/verification process it's done by libfprint,
maybe this is the difference?

New ubuntu user

my name is Vojta and I am a blind Linux user from Czech Republic.
I have recently bought Lenovo Thinkpad X230 with Upek fingerprint reader
(sorry for possible misspell).
I would like to try it with fprint, but I have the following problem:
I want to use my fingerprint just for sudo.
So I added your PPA to my Ubuntu 12.04 installation, installed fprintd
with dependencies.
When using fprintd-enroll, everything works, but when doing sudo, it
prompts me for a password first and when I just press enter, it says,
that no fingerpint could be found in the hardware.
I tried enrolling with
pam_fprint_enroll but at the end it exits with data storage failure
error -1.
And still I am aksed for password first and after then for my fingerprint.
This is content of my /etc/pam.d/sudo:


#auth       required   pam_env.so readenv=1 user_readenv=0
#auth       required   pam_env.so readenv=1 envfile=/etc/default/#locale
auth       required pam_env.so
auth       sufficient   pam_fprintd.so
auth       sufficient   pam_unix.so try_first_pass likeauth nullok
auth       required pam_deny.so
 <at> include common-auth
 <at> include common-account
 <at> include common-session-noninteractive

end of my config file.
If you want more debugging info, just tell me.
Please help me, I would like to use this hardware when I have it.
