This user used Universal-USB-Installer-1.8.9.4 to write a Ubuntu 12.04
Server (32bit) image to a USB stick - a somewhat different technique from
yours. The tool used to create the USB image quite possibly modified and
damaged the image when writing it out.

AfAIK, there is no well-documented account of dd, cat or cp reproducibly
failing to write a Debian installation image properly to a USB device.
