Hi! 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. -- Regards, Wojtek
