Analyze it. Find out, how the protocol works. Are commands used or registers? At which time which command is used? E.g. if a command is used multiple times during the actual scan and returns lots of data it's most probably the "read_scan_data" command (or however you want to name it). A command that is used only once immediately beforet he scan may be the "start_scan" command. Putting the usb snoopy logs somewhere on a web site might also help. Maybe someone recognizes a pattern or has seen that protocol before? Bye, Henning
