Introduction

This revolutionary USB Extender utilizes technologies that streamlines and enhances functionalities
between USB devices and multiple PCs. Current solutions from other companies provide minimum
functionality at high costs. They use significant amounts of resources and effort to achieve the

required features, whereas this USB Extender utilizes significantly less resources for more features.
Most solutions allow printer-only peripheral devices. However, this USB Extender allows you to use a

multi-function combo device such as a Multiple Function Printer. Another added benefit is that you
can connect multiple printers/scanners/faxes to the USB Extender through a USB Hub. These are

just some of the features that make our product one of the standards today. The USB Extender
application provides a user-friendly interface between you and the USB Extender, enabling you to
monitor, manage and use the convenient and powerful functions provided by this USB Extender.

the middle that displays a list of all devices discovered on the network, a Search
button to get the current status of all USB Extenders and devices, and a button that toggles between

Status of USB Extender and Devices

The tree view also tells you the status of all the USB Extenders and devices that are discovered on
the network. Any inaccessible USB Extender might or might not show up on the list if it is either
disconnected from the network, powered off or suffering from other technical difficulties. The
device might be in one of the following states and there are different things you can do with it in
each of the states. Each status is represented by a specific icon.

Device Free

A device with Device Free status is unoccupied and ready to be connected.

This status icon indicates the device is occupied by another user on your network and you can not
connect to that device at the moment.

Device on Different Segment

segment from your PC. You can NOT connect to a device attached to such an Extender. Please check
your network settings. However you can still change its network settings.

If you select a connected device on the UI, you can see that the Connect Device button is
changed to Disconnect Device：

Clicking on this button releases the selected device for other users. Once you see the icon change
back, the device has been disconnected and other users will then be able to connect to it.

This operation is exactly like when you unplug a USB device from your PC’s USB port.
