Thanks for the reply!
I made some USB-logs with USB Snoopy and tried to decode them with the
decode.sh script, but the resulting file is always empty. Is there
something I should do before with the file cause its an windows-file? I
don't believe that I'm using it the wrong way.

./decode.sh USBlog.usblog

The file output is USBlog.usblog.decode but its empty.

Thanks MK
