About USB
USB (Universal Serial Bus) is a general-purpose serial interface designed to
connect a computer and low- to middle-speed devices. The standard was
developed by Microsoft, Intel, IBM, Compaq, DEC, Northern Telecom and
NEC, and officially released in 1996.
USB connection scheme is of a tree structure with one host computer as its
starting point (root). Up to 127 devices may be connected via several USB
hubs. In one USB bus tree, USB hubs may be cascaded up to 5 levels (or 6
levels including the device at the end). The maximum distance between the
host computer and the device at the end is 30 meters, and up to 5 meters of
device-to-device distance is allowed.
The USB standard supports both a low speed mode (1.5Mbps) and a high
speed mode (12Mbps). When a USB device is connected to a host, the
device notifies the host which speed should be used. Whenever a new USB
device is added, the host sets a schedule that determines at what interval
data should be sent to which USB device. All USB devices support Hot
Swap feature that allows each device to be added or removed while the PC
is online. Not only that, all USB devices support Plug and Play function that
enables the devices without rebooting the PC. Due to these two features,
the user can quickly employ a USB device anytime it is needed.
Each USB device is equipped with one or more downstream port(s) (Type B
connector) and one upstream port (Type A connector). Type A and Type B
connectors differ in shape, and are used to avoid connecting cables in a
wrong direction. To connect two USB devices, the downstream port on one
device needs to be connected to the upstream port on the other device via a
USB cable. A USB device may connect to any port as long as the connector

Congratulations on your purchase of UH-400 4-Port USB Hub! The USB
Hub provides additional three USB ports to the PC. In one USB bus tree,
four additional UH-400s can be cascaded. In this 5-level cascade
configuration, up to 127 units of USB devices such as printers, TAs, mouses
and USB cameras may be connected to the tree. The PC can access all of
these USB devices without consuming its computer resources (IRQ, etc).
The USB hub operates in both Self Power mode and Bus Power mode, and
supports the full-speed mode (12Mbps) and low-speed mode (1.5Mbps). As
specified in the USB standard, the USB Hub supports Hot Swap. Note:
please use the Self Power mode when cascading two or more UH-400s.
Supports USB Specification 1.1
Equipped with one upstream port and four downstream ports
Each downstream port is equipped with LED indicator for monitoring
port status
Operates under both Self Power mode and Bus Power mode. *
Fully supports Plug & Play
* Bus Power mode is functional as long as the current consumption at each
port does not exceed 100mA. If it does, please use the USB Hub under
Self Power mode with the included AC adapter to provide enough current
to each port.

type matches. No loop is allowed in one bus tree, and a computer other than
the host PC may not be included in the tree.
USB devices operate from either an external AC power adapter ("Self
Power Mode") or from power supplied through the USB cable ("Bus Power
Mode"). USB devices with lower power consumption, such as mouse and
keyboard, may use the Bus Power Mode to directly draw its power from a
USB cable. Devices with Bus Power Mode support are further subdivided
into low power consumption devices (up to 100mA) and high power
consumption devices (100 to 500mA). Since no AC adapter is required,
devices with Bus Power Mode support are easy to setup. However, an AC
adapter may be required when USB devices with high power consumption
are in use. Please always check whether enough power is supplied to all of
the USB devices attached.
With traditional external interfaces, each connected device requires its own
resource. If the system has a keyboard, a mouse, a serial port and a printer,
for instance, a total of four IRQ resources are used for these devices. On the
other hand, a USB device uses only one resource even when up to 126
additional devices are attached to it. Furthermore, all USB devices use the
same USB cable; the user no longer needs to obtain multiple cables with
different connector types.
Undoubtedly, USB is a cost-effective, easy-to-use new connection standard
with a minimum computer resource requirement. Many computer
peripherals with USB support are already available today.

This chapter explains how to connect USB devices or another USB hub to
UH-400.
USB devices may be connected in a tree structure (USB Bus Tree) with one
host computer as its starting point (root), and one USB bus tree may support
up to 127 devices. A USB hub is counted in the tree as one of the 127
devices. While providing additional ports for these USB devices, a USB
hub also supplies power to the attached devices. In one USB bus tree, USB
hubs may be cascaded up to 5 levels(or 6 levels including the root hub).

Please firmly plug the USB connector of the USB peripheral device into the
downstream port (Type A Connector) on the UH-400. The time your PC
requires to detect the USB peripheral device may vary with each PC
environment. If your PC does not detect the USB device after several
minutes, please re-insert the USB device into the USB Hub. For details on
installation procedure of the USB peripheral devices, please refer to the
user's manual for each USB device.
There are two patterns for connecting two USB hubs to each other:
"cascading another USB hub to UH-400" and "Cascading UH-400 to the
other USB hub."
Cascading UH-400 to another USB hub
Using a USB cable, connect the downstream port (Type A connector) of
UH-400 to the upstream port (Type B connector) of the other USB hub.
Cascading another USB hub to UH-400
Using a USB cable, connect the upstream port (Type B connector) of UH-

Please consult the following troubleshooting information if you have
encountered a problem during installation or operation of this product.
Is the AC adapter attached to the USB Hub?
If any of the USB peripherals attached to the USB Hub requires 100mA or
greater current, attach the AC adapter for Self Power mode operation.
Is the USB cable firmly inserted into the USB Hub?
Please make sure to insert the cable firmly into the USB Hub.
Are you using the USB cable that came with the product?
Please use the included USB cable or other PLANEX USB cables to
secure the connection with the other USB port.
Has there been any attempt to insert/ remove a USB cable during
device installation or while the USB or other USB devices are in use?
Although the USB standard supports hot swap, you may not connect or
disconnect a USB cable to a USB device during its installation or
operation. Before disconnecting a USB cable from the USB device,
please make sure that the device is not in use.
Please try inserting/removing the cable slowly.
An abrupt insertion or removal of the USB cable may result in some
abnormal behavior of the device. When inserting or removing the cable,
please do it slowly.
