Debian distribution doesn't have USB startup disk creator software. However, you can make live USB stick based on Live-DVD ISO from command line.
sudo dd bs=4M if=/<path>/<to>/<live DVD>.iso of=/dev/sdX && sync
where sdX is the USB device name. Don't use trailing digits like
sudo dd bs=4M if=/home/serge/Downloads/debian-live-8.7.1-amd64-cinnamon-desktop.iso of=/dev/sdb && sync
