I cloned upstream git repository[1] and built it then replaced
/usr/lib/x86_64-linux-gnu/libfprint.so.0.0.0 with
libfprint/.libs/libfprint.so.0.0.0 manually, and got the following
debug print:

Actually the driver ID for UPEKE2 was modified from 1 to 13 (= 0x0d)
at commit ea6d5ba[2]. I rewrote the UPEKE2_ID to 1 and built the
library, it works again. So, I regenerated my fingerprint data with
fprintd-enroll (pam_fprint_enroll did not work for me), then copy
/var/lib/fprint/nov/000d/00000000/ to
~/.fprint/prints/000d/00000000/. Now, everything is all right!
