Hi Chris:

You should not need to use mke2fs before writing the image to the
USB device.  The file system is all built-in to the image file,
and the dd command writes everything (boot block, partition
table, and fs contents) to the USB device.  One thing to look at
carefully is to make sure that your USB device really is using
/dev/sda, and not /dev/sd[bcd] ... and also make sure that when
using dd you set of=/dev/sda (if your device is /dev/sda) and NOT
/dev/sda1 (this would be the first partition on /dev/sda).

I made a few more changes to the liveusb.sh script, to account
for different USB devices (you can now specify the device on the
command line) and the new version is available at the same
location (ftp://ftp.applios.net/pub/fjb/LiveUSB/liveusb.sh).
