Be sure to substitute "/dev/sdd" by your actual USB device. A common mistake is to just to create a raw image of the partition on the USB device (like "/dev/sdd1"). In this case you miss partitioning information, other partitions and the bootsector.
Similarly, substitute "/home/laserdude/usb-device-image.raw" by the actual image path and name you want to use.
You may have to run the dd command as root.
