Hi,
I have captured the packets on Wireshark on Linux while running Windows
XP in virtualbox.It appears to break down the prints into pairs of
packets around packet no.1266. I have no idea how to interpret the
capture data. Would appreciate some assistance.
The insertion capture is here:

Reading capture is here: http://www.comp.nus.edu.sg/~benjamin/fp/reading
Thanks.

Hi,
Hi Benjamin,
I dont mind working on the driver as long as i have someone to guide me
through the process.
Join #fprint channel at irc.freenode.org
I have looked through the git repo for libfprint. However, I am not
very
clear as to which parts have to be written to support a new device.
From what I understand, i need to sniff the usb packets to
determine what
data is sent during startup,idle and while reading the prints. Then
i need
to write C source with functions to detect the state of the reader
and read
in the data and transmit it over the internal API for processing?
Usually I write simple prototype just to retrieve image from scanner,
see
https://github.com/anarsoul/fprint_aes1660 and
https://github.com/anarsoul/fprint_aes2550
Then I move working skeleton into libfprint driver
The enrollment, storage and verification process are all being
performed by
a standard library?
Yep, driver just needs to provide image to the library.

Vasily
Thanks
Ben
