[fprint] fprintd rejects sedond and other verify attempts

[Jaroslav Barton]

Hi all!

I've just updated kernel to 2.6.28.1-19.fc10 and fprintd stops working. First 
verify, identify, enrol attempt is allowed, but second and others results in

pam_fprintd(su): Verify result: verify-unknown-error

or

$ fprintd-enroll djaara
Using device /net/reactivated/Fprint/Device/0
Enrolling right index finger.
Enroll result: enroll-unknown-error

without I touched sensor.

I tried update libusb from version 0.9 to 1.0 (downloaded from sf.net). This 
allows me first attempt.

Are there some changes in libusb, or kernel which causes this problem?
