I have successfully recorded USB communication between the fingerprint
scanning program and the fingerprint reader reported by lsusb as: ID
138a:0011 Validity Sensors, Inc. VFS5011 Fingerprint Reader.

The fingerprint scanning program was running on Windows in a virtual
machine (QEMU) and communication was recorded with wireshark running on the
host Linux system.
The results are available (temporarly) at
https://sites.google.com/site/wzab66/p2.bz2 you can read them e.g. in
wireshark (decompress with bz2 and run "wireshark p2").
The session included 3 successfull scans and much more unsuccessful scans
(probably running on VM, the software had some problems with receiving or
processing data?).

I hope, that the above dump may be helpful in development of free Linux
driver for VFS5011 fingerprint scanner.
