A topology map for a system is generated and displayed on a display device to indicate the various components which make up the system. The various components are indicated using icons each of which represent a respective one of the components. When a device is added to the system, a graphical image representing that device is automatically displayed in a graphical user interface. Similarly, when a device is removed from the serial bus, the graphical image representing that device is grayed out, leaving a shadow of the graphical image until the device is either re- coupled or the system is powered off. In a preferred embodiment, a user specifies a source device and a receive device is manipulating the corresponding icons so as to cause a data transfer between the source device and the receive device. In another embodiment, one or more task windows are included in the interface which hel p the user select the task to be performed. Once selected, controls, commands and data related to the task are displayed within a control display window of the graphical user interface. When a task requires data to be sent between devices, the flow of data between the devices over the serial bus network is graphically represented b y an animated data stream within the graphical representation of the bus structur e.When the data stops flowing between the devices, the animated data stream disappears. Data transfer operations may include the transfer of video data, audio data, or both. In a further preferred embodiment, the digital network corresponds to the IEEE 13 94 Serial Bus Standard.
