If you're using VMware for testing, it's normal practice to mount your ISO as a DVD device.
That's fine for installs, but it's on a read-only filesystem. Sometimes you want to test how a true USB flash drive works. Like the convenience of updating ISO files without needing to build a whole new ISO. Fortunately, you can create a virtual USB drive which can be used for booting.
