[Fingerforce-devel] Bug#584563: enroll fails with error -22

[martin f krafft]

Package: fprint-demo
Version: 20080202-3
Severity: normal
File: /usr/bin/fprint_demo

[filing this on a train, sorry if it's a duplicate]

I am trying to enroll fingerprints with fprint_demo, using the
Thinkpad X201 builtin fingerprint reader (see below for lsusb -v
output). Unfortunately, as soon as I hit any of the "Enroll"
buttons, a dialog opens telling me to scan one finger 1 times, and
another informing me that "enroll failed with error -22".

I have looked into strace but cannot find any problems. In the
attached strace, I removed all EAGAIN and POLLIN lines, and it seems
that the error follows a URB transfer.

Let me know if I can help debug this further.
