There are a hell of a lot of names for them, and I think native speakers of English use a variety: http://dispenser.homenet.org/~dispenser/cgi-bin/rdcheck.py?page=USB_flash_drive http://dispenser.homenet.org/~dispenser/cgi-bin/rdcheck.py?p... I think most native speakers who aren't technical would pick something from that list which probably doesn't have "USB" in it and then wrap it with "little" and "thing" - eg. "little thumb drive thing".
