[fprint] Enroll failed with error -22

[miguel Gómez gonzalez]

Hi 

I just got a new Lenovo think pad t400 with device:
  
  idVendor           0x147e Upek
  idProduct          0x2016 Biometric Touchchip/Touchstrip Fingerprint Sensor


Im working over rhel6 Kernel 2.6.32-71.7.1,  and this is the packages installed:
libfprint-devel-0.1.0-19.pre2.el6.x86_64
libfprint-0.1.0-19.pre2.el6.x86_64
libusb-devel-0.1.12-23.el6.x86_64
libusb1-1.0.3-1.el6.x86_64

and installed from source pam_frpint-0.2 and fprint_demo-0.4, but whenever i try to enroll my fingerprint i got the message: Enroll failed with error -22 but have not found anything in the web related to error - 22. 

fprint project demo  shows in the status bar:
Status: Device ready for use.
Driver: upeksonly
Imaging device.

Im only able to open the device as active as root.   in both demo and pam_fprint_enroll.  Any help is very much appreciated 




Mike
