An invention is provided for limiting power during an unconfigured state of a USB device. The invention includes a first voltage regulator, which supplies a first voltage, in electrical communication with internal device logic of a USB device. A second voltage regulator is also included that supplies a second voltage that is higher than the first voltage. In addition, a current limiting resistor is included. The current limiting resistor is coupled to an output of the second voltage regulator and is further in electrical communication with the internal device logic of the USB device. The current limiting resistor is configured to allow a maximum current of 100 mA from being provided to the internal device logic of a USB device from the second voltage regulator.

System and method for interconnecting downstream USB ports using limited power during unconfigured state

A computer-implemented USB (Universal Serial Bus) monitoring and data displaying utility for monitoring and displaying information pertaining to a plurality of USB devices connected to a computer, the displaying being performed on a computer display screen communicably coupled to the computer, the information pertaining to the plurality of USB devices including status information pertaining to the plurality of USB devices. The USB utility includes a monitoring view implemented in a window of the computer display screen, the monitoring view including a set of condensed individual device information sections, each of the condensed individual device information sections displaying condensed information pertaining to one of the USB devices. The condensed information includes an identity of an associated USB device, and one of a hub identifier, a port identifier, and a data transfer indicator pertaining to the associated USB device, the hub identifier identifying a hub to which the associated USB device is currently connected, the port identifier identifying a port to which the associated USB device is currently connected, the data transfer indicator indicating whether data transfer currently takes place with respect to the associated USB device.
