A Universal-Serial-Bus (USB) device includes a PCBA mounted inside a molded plastic housing structure such that metal contacts are exposed on a plug portion of the housing structure, and includes a metal plug shell attached to the housing structure such that an upper wall of the metal plug shell is spaced from the metal contacts by a predetermined gap distance. A USB controller IC is mounted onto a relatively narrow portion of the PCBA under the metal contacts to reduce overall length of the USB device. The metal plug shell is molded or snap-coupled onto tabs formed on the plug portion of the housing structure. An optional locking collar secures a rear edge of the metal plug shell to the housing structure. An optional rear cover is attached over a rear opening of the housing structure and secures a rear edge of the PCBA.
