Lantronix UBOX 2100 - Manual (Page 20)

4: Using USB Devices on the Network
UBox User Guide 20
Note: Some USB devices require additional action before you disconnect
your USB device. For example, some USB devices require you to stop the
USB device's software. If your USB device requires such action when the
device is directly connected to your computer, please perform them before
clicking the Disconnect icon in the Lantronix UBox software.
If you forget to disconnect a USB device, the USB device automatically disconnects if
your computer goes to “sleep” or “hibernates,” your computer is turned off, or you
disconnect from your network.
In the worst case, where a USB device has been left in use and you cannot get the
other computer to disconnect it, you can “forcibly disconnect” the device. While this
action is not recommended, you can learn more about it in
Using Forced Device
Disconnect on page 25.
Using Multiple UBoxes and USB Devices
There are numerous ways to connect USB devices to one or more UBoxes.
Compound Devices
You can connect up to eight USB devices to one UBox. While the UBox 4100 only
has four USB ports, and the UBox 2100 has two, each supports up to eight devices
because of how compound USB devices work. Compound USB devices are devices
that have multiple components connected to an embedded USB hub inside one USB
device. A single PC supports connection of up to 50 USB devices.
For example, some compound devices have two components: a scanner and a
printer. Other compound devices have three components: a printer, a card reader,
and an HID device for buttons on the printer.
One UBox with Multiple Users
The UBox allows up to 10 users to connect to a single or to a set of UBoxes using the
same UDP port. You can support more users by setting up additional UBoxes with
different UDP port numbers.
Multiple UBoxes and USB Devices
You can view up to eight UBoxes in the Lantronix UBox software.
For example, if you are using all of the USB ports on eight UBox 4100 units, you can
view up to 32 USB devices in the UBox software; however, you can only have 12
USB devices simultaneously connected to your computer.
