  • 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.

  • Enhanced universal serial bus
    Patent number: 6334793
    Abstract: An enhanced Universal Serial Bus (USB) interface provides for the communication of standard USB signaling and non-standard USB signaling, which may be alternate voltage signals. The chassis within data processing devices operable for receiving such an enhanced USB connector into an enclosed enhanced USB receptacle provide a keying configuration so that the standard USB connector portion is not matable with the non-standard USB portion.

  • System and method for voltage switching to supply various voltages and power levels to a peripheral device
    Patent number: 5884086
    Abstract: Within a data processing system, such as a personal computer, non-standard, or auxiliary, voltage and current may be supplied to an attached peripheral device along with standard Universal Standard Bus (USB) power and signalling. A communication protocol is enabled between the host system and the peripheral device to permit the peripheral device to communicate its power requirements to the host device so that the host device can switch the proper voltage and current through the USB cable to the peripheral device. This allows the peripheral device to obtain power without having to connect to an AC power supply.
