[fprint] DigitalPersona UareU 4500 working

[Timo Teras]

Hello list,

I have reverse engineered the uru4500 encryption scheme from the binary
only drivers. And I have a modified libfprint here that gives sensible
data from this device - fprint_demo seems to work with it just nice.

If I'm to clean up the patch (and someone can test it with the older
devices) would it be acceptable as such for merging?

Or should I document the encoding scheme, and someone else write the
fprint driver modifications?

Thanks,
 Timo
