FIG. 15 shows a USB storage device having a locking cap, according to various exemplary embodiments. The illustrative USB storage device 1510 includes locking cap 185 attached or locked to a USB connector (under the surface of the locking cap 185). Locking cap 185 may also include one or more connection points 1520. Connection points 1520 may vary with respect to whether one connection point may be hollow all the way through to a second connection point, or whether one or more connection points may be close-ended. One or more connection points 1520 may have a chain, string or other tie mechanism connected or in other contact with the connection point 1520. Such a chain, string or other tie mechanism may be used to connect a locking cap (e.g. locking cap 185), the associated or locked USB connector, and/or a device or other piece of equipment associated with the USB connector (e.g. USB storage device 1510), to some other item, such as a key ring. An advantage of such a set-up (or other similar set-ups with weighted items) is that a USB storage device may be disconnected from a locking cap, and the associated key ring, and inserted into a computer, without having the weight of the key ring and/or keys cause the destruction of or compromise the USB connector, USB storage device and/or the computer. Further, the keys (or other item) may be used without the inconvenience of undocking the USB storage device (or other similar USB item). Additionally, there is a reduced risk of losing an item associated with the locking cap (e.g. a portable USB storage device), since the locking cap has the item securely fastened to another item, such as a key ring. The likelihood of losing an item with various particular embodiments of the locking cap are decreased when two separate spots or locations on the locking cap require simultaneous actuation in order to release or unlock the locking cap. A further advantage of a locking cap is the reduced risk of losing a cap and the resulting exposure of a USB connector. In many cases, the USB connector is the most sensitive portion of the associated device or equipment, with respect to possible damage.
