[fprint] Hello All

[Michael]

I have spent a bit of time with libusb lately, and I notice that the fprint 
library is still relying on libusb-0.1.  I was wondering if everyone would be 
interested in some patches to update to the current version libusb-1.0.  I 
have briefly scanned and I see what appears to be 9 files that would be affected, 
all in libfprint.  But before I get to digging, I just wanted to see if this 
is something that would help the project.

Cheers,

Michael
