You'll have to do a trick:

Boot from the live-cd.

copy the file /mnt/live/LiveOS/livecd-iso-to-disk to /tmp

Edit the file and remove the lines:

if [ -z "$ISO" -o ! -f "$ISO" ]; then
     usage
fi

Remove the line

[ -d "$CDMNT" ] && umount $CDMNT && rmdir $CDMNT

from cleanup.

Change

CDMNT=$(mktemp -d /media/cdtmp.XXXXXX)

into

CDMNT=/mnt/live

and remove the line:

mount -o loop,ro $ISO $CDMNT || exitclean

Save the file.

Plug in the USB device, note the name of the
partition (e.g. /dev/sdb1) and unmount it.

Now do the transfer (one line):

/tmp/livecd-iso-to-disk --noverify --overlay-size-mb 512 /dev/cdrom 
/dev/sdb1

Works for me.

Be careful with the partition names.

To be safe, remove the disk drive from the machine before
experimenting.
