  • Methods, systems and computer program products for logically segmenting devices on a universal serial bus
    Patent number: 6535947
    Abstract: Methods, systems and computer program products are provided for segmenting a plurality of Universal Serial Bus (USB) devices connected to a common root hub into clusters. The devices may be segmented based on the connection topology. Such a segmentation may be performed without user intervention to define the clusters by designating a particular port(s) of USB hubs as expansion ports such that a USB hub connected to an expansion port starts a new cluster and may act as a cluster root hub. Devices connected to a cluster root hub may be considered in the same cluster if there is no intervening cluster root hub.
