It is still recognised as a new device the first time the operating system
reads it. To give an example, I regularly use my USB flash drive on my
computer, however If a friend connects their one it installs it as a new
device. I'm only guessing but I'd imagine they each have some form of I.D.
and the system simply recognises it as a new USB device, unaware that it is
another USB flash drive until it is installing it.
