Hi, the files probably didn't went through the mailing list - you can download them at <http://www.uloz.to/8352470/fprint-logs-tar-bz2>, I also included one log from usbmon (from different session than the Wireshark log).
The log captures connection of the device to VirtualBox machine and reading of fingerprints. The individual actions could be separated by the time stamp. I started to look on the log to find more about what happening. I have found, that the large portion of data comes from the device after the package with following data is released from the computer: 13204c01 00004b04 00785634 12550700 8042007f 00001449 03002000 c8 After this follows response with few (~3) packages with size 16384 B (=128x128), and the last package is smaller, but still has significantly more data than other responses. I highly suspect this part of communication to be actual receiving of the fingerprint. Although, ff the data are really the fingerprint, then it is surprising, that the fingerprint is transfered in once, not by strips as in other sensors. There is another thing, that confuses me highly. During all the communication, there are few repeating sequences of lots of packages with larger portion of data (~200 B) transfered _from_ computer _to_ the device. They are usually confirmed with "42010001" from the device. I would like to know, what is purpose of those packages. I think, there is too much of data transfered to be just control sequences. I was thinking about encryption keys, or firmware, or fingerprint patterns or something like that.
