Well I have Lenovo 3000 N100 notebook with AuthenTec AES2501 fingerpint reader (08ff:2580). I'm using Debian Squeeze amd64, but hope that it's similar to Ubuntu.
The problem is that fprint_demo and pam_fprint_enroll doesn't read my fingerprint. They just stop on finger scanning dialog. Sensor is working - aes2501 demo program shows me my fingerprint. Any ideas what is the problem?
