[fprint] device support

[Mbarak Bujra]

Hi, I have an HP Pavilion dv7 which came with a DigitalPersona (that
was the name of the software) fingerprint reader  (in the laptop
keyboard)
When I install fprint-demo it sais that no device could be found

the usb-id is 138a:0001
this ID is not recognized by Ubuntu (i.e. - there is no name beside the ID)

I was just wondering if the reader is supported and if it is, where to
add this usb id so that i can use it

thanks in advance
