OK. It might be hidden: when a firmare download takes place the device 
re-enumerates (disconnect and reconnect). When it re-enumerates with the 
same USB IDs usbsnoop will restart the log-file from the beginning and 
deletes the firmware download.

Sometimes you can see a difference, by looking with lsusb -v before and 
after downloading the firmware (or usbview on Windows).

If you are successfully using the device in Linux (after a replug) it will 
need probably no firmware.
