Identifying a USB Network Interface
If you have multiple USB interfaces installed on your PC and you need to
establish which physical interface is associated with a logical interface name (e.g.
LON1 or LON2), you can use the Wink button on the USB tab to make that
determination. After you select a USB interface on the USB tab, click Wink.
The SVC LED on the currently selected USB interface will then illuminate for
several seconds, allowing you to identify the network interface.
Removing a USB Network Interface
Most users will never need to remove a USB interface definition from a PC.
However, you might want to remove a USB interface definition if you want to re-
use the logical name that the interface is using.
Each USB interface is serialized during manufacture, and the L ON W ORKS
Interfaces application keeps track of each of these network interfaces, even after
they have been detached from your PC. This means that a particular USB
interface will continue to use the same L
ON W ORKS network interface name (e.g.
LON1 or LON2) once it has been inserted and recognized by your PC, regardless
of how many USB interfaces are plugged into the PC, or in which order. It also
means that each USB interface will retain the network interface name assigned
to it, even after it has been detached from your PC. Normally, detached USB
interfaces are hidden by the L ON W ORKS Interfaces application. If you want to see
all USB interfaces with the L ON W ORKS Interfaces application, including those
that are currently detached, select the Show Detached Interfaces check box on
the USB tab, as described in the previous section.
To remove the normally hidden definition for an interface and free the logical
name assigned to it, first detach the USB interface from the PC. Then, select the
Show Detached Interfaces check box, so that the detached USB interface will
be listed on the USB tab. After this, select the interface you want to remove (it
must show a status of Detached), and click Remove.
This process removes all knowledge of the detached interface from Windows. If
the same USB interface is subsequently connected to the PC, the Found New
Hardware wizard will appear as it did the first time the interface was connected
to the PC, and the L ON W ORKS Interfaces application will assign the interface a
new logical name.
