A Universal Serial Bus docking station is provided in which a USB hub includes a housing which may receive at least one additional USB module which is connected to the USB hub without the use of an additional cable. In a preferred embodiment of the invention, up to three USB modules may be inserted into the housing in stacked arrangement. In addition, each USB module maybe used as a stand alone unit by snapping a sleeve onto the rear of the module. Still further, a USB connector is adapted for use standing vertically from a circuit board and being retained by spring clips extending through the circuit board in a direction substantially parallel to the longitudinal axis of the connector.
