Ethernet Adapter
Thank you for purchasing Belkin Components' USB Ethernet Adapter. Now, you can
easily connect any USB-equipped notebook, portable, or desktop computer to an Ethernet
local area network. The product consists of a small plastic enclosure incorporating both
USB and 10Base-T (RJ45 TP) Ethernet ports, plus the associated software.
Windows® applications that communicate via an Ethernet card will also work with the
Belkin USB Ethernet Adapter. It offers a Plug-and-Play solution for network connectivity,
eliminating the need to insert cards or shut down the system at connection time.
Our adapter conforms to both USB and Ethernet specifications, and functions as a fullspeed USB device. In addition, the hardware includes an Ethernet controller, appropriate
memory buffers, and on-board non-volatile memory for network configuration. The unit
requires no external power supply; it is powered directly by the Universal Serial Bus.
The provided software supports the Windows® 98 operating system environments. The
CATC software drivers provide a bridge between the existing network layer protocols and
the USB protocol stack, hiding the details of the USB interface from the application
programs. This manual explains how to connect and use the Belkin USB Ethernet Adapter
hardware and software with your PC and network environment.

The Ethernet Adapter does not work when
connected through a bus-powered USB hub.
The Belkin USB Ethernet Adapter is a (USB)
bus-powered product. Current versions are
considered high power devices (that is, they
consume more than 100 mA when in operating
mode). Thus, they cannot be used downstream
of bus-powered hubs, which deliver only 100
mA per port. The adapter will enumerate
correctly, but the operating system will not
allow it to come up to full power.
You replaced the Ethernet Adapter with a new
Ethernet Adapter and it does not work.
Each Belkin USB Ethernet Adapter has a
unique encoded Ethernet identifier. Unplugging
the adapter from the Windows® machine, and
plugging a different adapter into the same port,
will cause a problem in the protocol software.
The original device should first be completely
The installation procedure produces the
message: Hardware and software support for
USB was not found.
The program detected that your computer is not
configured for proper USB support. There are
four main conditions to check:
1. You do not have a USB connection on the
motherboard. The solution is to upgrade your
motherboard or add a USB controller card.
2. It is possible that you do have the proper OS,
but there is no connection between the
motherboard and the USB connectors on the
3. It is possible that you do have the proper OS,
but the controller on the motherboard is
The LED is off.
There are two main possibilities:
1. The host computer might be in standby mode,
and not supplying full power to its devices.
2. The Ethernet Adapter did not properly
enumerate. Enumerate is a USB term meaning
the system has identified and configured the
device and given it a unique address.
The LED is blinking.
The Ethernet port connection might be
inoperable. Check the Ethernet connection.
Replace the Ethernet cable.
You require additional information about
adding or removing network drivers.
