Have you tried using the Startup Disk creator that comes with Ubuntu?
You give it an ISO file and the USB device and it creates a bootable

There is also the package 'unetbootin' which you can install and does a
similar job.

Works with standard Ubuntu ISO disks. Not sure about a customised ISO,
but worth a shot.
