The D-Link DUB-H4 2.0 is a Hi-Speed Universal Serial Bus 2.0 4-port hub with backward
compatibility to USB 1.0 and 1.1. It provides an out of the box industry standard
that allows connection of up to four USB peripherals or devices to your USB ready
PC or Mac. The D-Link DUB-H4 is targeted at PC and Mac users that are expanding
the number of USB ports on their system.
The D-Link DUB-H4 2.0 is designed to provide quick and easy access to the four type
"A" downstream ports for connecting USB peripherals, devices or other USB hubs.
A single type "B" upstream port connects the DUB-H4 to the host computer, or another
USB hub enabling up to 127 devices to be connected by cascading multiple hubs. Configured
directly by the operating system, the D-Link DUB-H4 2.0 operates seamlessly with
both Microsoft Windows and Apple Macintosh Operating Systems.
As a standard USB hub, the D-Link DUB-H4 buffers USB data from any attached peripheral
in compliance with USB specifications to provide an invisible extension of the USB
bus. Supporting both low speed (1.5 Mbps and 12Mbps**) and Hi-speed (480
Mbps*) devices, each port creates a bridge between the peripheral and
Diagnostic LED's located on the top of the device provide power state (self-power)
and port status on each port. The DUB-H4 2.0 is packaged with all necessary documentation,
a 6-foot hi-speed USB 2.0 'A' to 'B' cable and an AC power supply to ensure that
the user is able to easily and quickly install and use the device.
