Thank you for purchasing the Hubport, a self-powered Universal Serial Bus (USB) hub designed to
provide a convenient and effective means of bringing USB connectivity to your PC, server, or laptop.
Hubs, which are critical components in the USB architecture, are wiring concentrators that enable the
attachment of multiple devices, thus converting a single attachment point into multiple attachment
points. USB architecture allows a cascaded multiple hub configuration with certain power limitations
(explained later in this section).
Digi’s Edgeport product, which is a USB-to-serial converter, can be connected to your Hubport device,
enabling you to install one or more Edgeports.
See the following figure.
Example of a typical hub configuration
Each hub has an upstream port, connecting to the host, and multiple downstream ports, connecting to
downstream devices, possibly including other hubs. A hub can detect attachment and detachment of
downstream devices and enable and monitor the distribution of the power to downstream devices via
their integral hardware and the operating system.
Each USB device reports its power requirements to the operating system, which then enables and
disables the device as a function of its power requirements and the amount of available power. High-
powered devices typically need to be connected to a self-powered hub, such as the Hubport, which
obtains power from its external power supply and provides up to 500 mA for each downstream port.
Only low-powered devices, such as a mouse, can be connected to a bus-powered hub, which obtains
power from its upstream host and provides up to 100 mA for each downstream port.
Due to the limited available power for bus-powered hubs, cascading two bus-powered hubs is an
illegal topology, and devices connected to the second hub will not function. USB specifications limit the
connection of a bus-powered hub to a self-powered hub or host only. All Hubports, except the
Hubport/4c in bus-powered mode, operate as self-powered hubs, and are not affected by this
limitation.

Hubport® USB Hub Installation Guide 6
According to the USB specification, the maximum limit of hubs cascaded in a series cannot exceed five.
In other words, you may have a maximum of five hubs between any device and the host. This does not
mean that the maximum number of hubs in a system is five; up to seven hubs can be connected
parallel at any given level.
You must tally both external and embedded hubs when counting downstream hubs.
Connect to your Hubport
To connect the cables included with your Hubport:
1. Plug one end of the power supply into the back of your Hubport and the other end into an AC
outlet.
Note Power to this product may be supplied by a UL Listed Direct Plug-In Power Unit marked
“Class 2 with a minimum rating listed in the Hardware specifications and device LEDs section
if used in the U.S. and Canada, or you use a power supply with a similar rating approved by
your local safety code, in other locations.
2. Connect the Hubport device to a PC or standard USB device.
nTo connect the Hubport to a PC, plug the Type A end of the USB cable into one end of
the PC's USB Type A slots and the Type B end of the USB cable into the back of the
Hubport.
nTo connect the Hubport to a standard USB device, plug the Type A end of the USB cable
into the Hubport and the Type B end into the device.
3. DC power/polarity:
nFor units equipped with a pigtail connection, follow the polarity markings on the cable.
nHubport/SuperSpeed units may be equipped with a removable terminal connec tor for
DC power. Follow the polarity marking on the device.
Current Hubport models
Legacy and obsolete Hubports
Installing Hubport drivers
Once you have connected the Hubport hardware, the operating system will detect the Hubport device
and will provide a notification that it is installing the Hubport drivers.
After the driver installation is complete, your new communication ports are ready and are numbered
sequentially following the existing ports in your system.
