Introduction
The revolutionary USB Server utilizes technologies that streamlines and
enhances functionalities between USB devices and multiple PCs.
Current solutions from other companies provide minimum functionalities
at high costs. They use significant amounts of resources and effort to
achieve the required features, whereas the USB Server utilizes
significantly less resources for more features. Most solutions allow
printer-only peripheral devices. However, USB Server allows you to use
a multifunction combo device such as a Multiple Function Printers.
Another added benefit is that you can connect multiple
printers/scanners/faxes to the USB Server through a USB Hub. These
are just some of the features that make our product one of the standards
today. The USB Server application provides a user friendly interface
between you and the USB Server, enabling you to monitor, manage and
use the convenient and powerful functions provided by USB Server.

Main Dialog Box
Once you have start up the program and grant it access through the

The main dialog box is consisted of a Control Menu (File, Options, View
and Help), a tree view in the middle that displays a list of all the server
and devices discovered on the network, a Search button to get the
current status of all USB Servers and devices, and a button that toggles
between Open Web Page and Connect Device depending on the node
you select on the tree view. The Open Web Page button toggles to
Connect Device when a device is highlighted.

10
Status of USB Servers and Devices
The tree view also tells you the status of all the USB Servers and
devices that are discovered on the network. An inaccessible USB
Servers might or might now show up on the list. 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.

11
Occupied by Yourself
When the device has been occupied, the icon and Status change to
indicate so.

12
Occupied By Other User
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
This icon with question mark indicates that the server’s IP address is on
a different network segment from your PC. You can NOT connect to a
device attached to such server. Please check your network settings.
However you can still change its network settings.
Unsupported Device
Some of the devices are not supported by USB server. Such device will
be identified by a stop sign icon as shown. Of course, connecting to an
unsupported device is not allowed.

13
Accessing a Device
To connect to a USB device, please select it on the tree view and click
on Connect Device button or double-click on it. This process might take
a few seconds up to a minute, depending on the complexity of the device.
Then you can operate a connected USB device as if it is connected
to your PC’s USB port directly.

Connect Device button is changed to Disconnect Device:
Clicking on this button releases the selected device for other users.
Once you see the icon turns back, the device has been disconnected

your PC’s USB port.
