USB DIRECTOR/4-PORT HUB  
2. Introduction  
2.1 Overview  
The USB Director/4-Port Hub is a medium-speed and  
standalone universal serial bus (USB) hub. The USB  
Director/4-Port Hub supplies four additional USB ports  
to attach devices and/or additional hubs. The hubs can  
easily be daisychained, up to five hubs deep in series,  
in any combination that does not exceed 127 devices,  
including the hubs. No additional software is required  
to support the Hub.  
Two models are available: the IC165A includes a  
110-VAC power supply and the IC165AE comes with  
a 220-VAC power supply.  
The Hub is compatible with the USB Version 1.0  
specification and supports the power-saving Suspend,  
Resume, and Remote wake-up operations.  
NOTE  
The USB specification does not allow for a bus-  
powered hub to drive another bus-powered hub. That  
is, two bus-powered hubs must be separated with a  
self-powered hub.

CHAPTER 2: Introduction  
The USB Director/4-Port Hub is a dual-powered  
device that can be powered via the uplink connection  
(bus-powered) or via an optional power supply (self-  
powered). When bus-powered, the four downstream  
ports support “low-power” devices rated at less than  
1
1
2
watt ( ⁄ amp @ 5 VDC) each, such as a camera,  
10  
printer, scanner, or another hub. “Low-power” devices  
can also plug into these ports. The power switchover is  
automatic when the optional power supply is plugged  
into the hub.  
Each downstream port supports either full-speed  
(12 Mbps) and/or low-speed (1.5 Mbps) signaling  
automatically.  
The hub and each downstream port are overcurrent  
and short-circuit protected.  
2.2 System Requirements  
To use the hub, you’ll need:  
• A PC or Macintosh computer that supports the  
Universal Serial Bus (USB).  
• Operating system with a generic USB hub driver.

3.1 Initial Checkout  
3.1.1 BUS-POWERED CHECKOUT  
While the host PC is powered on, connect a USB cable  
between the host’s USB type A receptacle and the Hub’s  
type B receptacle (uplink connection). The Hub’s  
power indicator, bus-powered, and the uplink port LED  
will turn on. Then the host PC will locate and run the  
generic hub driver supplied with its operating system.  
The hub driver will identify the USB Director—4-Port  
Hub and enable each of its four ports. The individual  
port’s LED will turn on, indicating that power is applied  
to its connector.  
When the initial checkout is complete, USB low-power  
devices can be attached to the hub. Refer to the  
instructions supplied with each USB device for  
their individual operation.

CHAPTER 3: Installation  
3.4 Power Controls  
When the hub is connected to the USB connection,  
1
it initially draws less than ⁄  
10  
of an amp from the host  
connection. Each port is enabled one at a time. Initially,  
1
all attached devices are only allowed to draw ⁄  
10  
amp or  
less each.  
When the hub is identified, it tells the host whether it is  
bus-powered or self-powered. If the hub is bus-powered,  
the device driver should only allow low-power devices to  
be enabled. If the hub is self-powered, the device driver  
can allow low-power and/or high-power devices to be  
attached.  
NOTE  
Early device drivers may not enforce these power  
limits. However, the USB Director/4-Port Hub is  
designed to automatically protect the host connection  
and the hub itself from overcurrent conditions if they  
exist.

USB DIRECTOR/4-PORT HUB  
4. Operation  
The USB Director/4-Port Hub is an extension of the  
host’s USB bus. You only have to plug it into the host  
USB connector to operate. The hub is hot-pluggable;  
you can plug it in at any time, even when the host PC is  
powered on. When attached, the operation is automatic.  
The host software will detect that a device has been  
attached to the USB bus, query the device to identify it,  
and load the appropriate driver. The hub driver will  
then enable the hub and each of the ports. If the hub  
detects a device attached to the port, it will notify the  
host. The host will then communicate with the device to  
identify it and load its device driver. (This function may  
vary depending upon the individual device.)  
The Hub has power on/off, overcurrent reporting, and  
suspend/resume controls for the hub as well as for each  
of the individual ports. The host can send a command to  
turn on or off the hub, and individual port, or a device  
attached to the port. Suspend is a global or individual  
device command that sets the device or hub into a  
low-power mode where it is virtually powered off  
(<500 microamps), yet allows a device to request a  
remote wakeup. A wakeup will be responded to with

a resume command from the host that takes the device  
out of suspend.

The Hub is supported by the Microsoft Windows  
generic USB hub driver supplied with the latest  
version of Microsoft Windows 95 also known as  
OSR2.1, Windows 98, and Microsoft Windows NT 5.0.

5. Troubleshooting  
5.1 Power Problems  
1
If an overcurrent condition of > ⁄  
2
amp is sensed at  
a port by the hub, that port’s power will be limited  
1
(< ⁄  
10  
amp). The condition will be reported back to the  
host, the host will shut off the port, and the port LED  
will be off.  
If a port LED is off, an overcurrent condition may exist  
on that port and/or the port that has been turned off by  
the host. To clear this condition, disconnect the device  
causing the fault and reset the hub by unplugging and  
replugging the uplink connection. All downstream  
devices will be reset.  
If the hub is self-powered, you should see the reset LED  
come on while the host connection is disconnected. If  
in self-powered mode, you can also unplug the power  
connection and plug it back in to create a reset.  
In bus-powered mode, if the hub has an overcurrent  
condition or if the sum of the current being drawn by all  
1
of the devices and the hub exceeds ⁄  
2
amp, the hub will  
shut itself down and the uplink port red LED will turn

CHAPTER 5: Troubleshooting  
on. If the uplink port red LED is on, disconnect all  
of the devices and reset the hub as described on the  
previous page. Then plug the devices in one at a time  
and run their applications, noting when the failure  
reoccurs.  
NOTE  
If a device is unplugged while in suspend mode, its  
configuration informaton will be reset. To reconfigure,  
simply reset the Hub.  
5.2 Other Problems  
The following is a list of symptoms, possible causes,  
and suggested solutions.  
Symptom: Reset (amber) LED is on.  
Cause: Uplink (host) connection is lost.  
Solutions:  
1. Upstream cable is disconnected. Reconnect.  
2. Upstream hub or host is powered off. Make  
sure all upstream hubs are powered on.  
25

USB DIRECTOR/4-PORT HUB  
Symptom: Hub host port red LED is on.  
Cause: Overcurrent condition exists.  
Solutions:  
1. Disconnect port 1 through 4 devices one  
at a time until the LED goes off.  
2. If all devices are removed and the LED  
is still on, reset the hub.  
To reset the hub, unplug its uplink connection  
and plug it back in.  
If the LED is still on, the unit is defective  
and should be replaced.  
3. If the LED is now off, reconnect the devices one  
at a time until the failure reoccurs. The last device  
connected to the unit is drawing too much  
current.

Symptom: A single port LED is off.  
Cause: The port has been disabled by the host. An  
overcurrent condition may exist on that port or the  
device driver identified a problem with the device  
and turned it off.  
Solutions:  
1. Disconnect the device. If the LED does not come  
on, reset the hub.  
To reset the hub, unplug its uplink connection and plug  
it back in.  
If the LED turns on, you can reattach the device.  
2. If the LED did not come back on after the hub  
reset, you might need to reset or reboot the host  
PC.  
NOTE  
These power controls are left up to the individual  
device drivers. Since it is early in the development  
cycle, and some of the USB device drivers do not  
support all of the controls, this may be the only ways of  
clearing the fault.
