[fprint] Enroll failed with error

[Alan Carvalho de Assis]

Hi all,

I am testing an external usb eikon upek (147e:2016) on Ubuntu 9.04
with no success.

All source code (libfprint, pam_fprint, fprint_demo, etc) is from
git://github.com/dsd/.

This is the error message I am getting:

root at metropolis:~/fpreader/libfprint/examples# ./enroll
This program will enroll your right index finger, unconditionally
overwriting any right-index print that was enrolled previously. If you
want to continue, press enter, otherwise hit Ctrl+C

Found device claimed by UPEK TouchStrip Sensor-Only driver
Opened device. It's now time to enroll your finger.

You will need to successfully scan your finger 1 times to complete the process.

Scan your finger now.
sync:error [fp_enroll_finger_img] unrecognised return code -4
Enroll failed with error -22


I search for these error message with no success, in fact I found the
second one here: http://article.gmane.org/gmane.linux.fprint/953 but
with no response.

Please help me with this issue.

Best Regards,

Alan
