1. I inserted my U60 network interface into a USB port on my computer, but the Found 

New Hardware Wizard did not open and the computer has not detected the device.  What 

should I do? 

 

 

Verify that you are running Microsoft Windows 8, Windows 7, Windows XP, Windows 2000, 

or Windows Server 2003.  

 

Verify that you have a USB 1.1, 2.0, or 3.0 host controller on your computer.  

 

Verify that other USB devices that you may have work on this computer.  

 

Verify that the OpenLDV 5 or newer software has been installed on this computer. You can 

do so by opening the Programs and Features application in the Windows Control Panel, and 

checking that the Echelon OpenLDV 5 item exists (or a newer version).  

 

Disconnect all extension cables and external hubs, and connect the U60 interface directly 

into a USB port on the computer using the supplied cable.  

 

Try inserting the USB interface into a different USB port.  

 

Remove all other USB devices from the computer. 

 

Unplug and re-insert the USB interface.  

 

Reboot the computer.  

 

Verify that the Service LED briefly flashes on and off when you insert the USB interface into 

the USB port. If it doesn’t, then no power is being supplied to the interface.  

 

Update your computer with Windows Update. Check that all of the optional software and 

hardware updates are installed.  Windows Update does not automatically select the software 

and hardware updates for installation.  Windows Update is available 

here

  

 

Repair the OpenLDV software installation. You can do so by opening the Programs and 

Features application in the Windows Control Panel, selecting Echelon OpenLDV 5 (or a 

newer version) and then clicking Repair.  Follow the instructions to repair the software, and 

then re-insert the USB interface.  

 

Check 

www.echelon.com/downloads

 for an updated version of the OpenLDV driver.  

 

2. I opened the L

ON

W

ORKS

 Interfaces application in the Windows Control Panel and the 

U60 interface is listed on the interfaces pane.  However, it does not respond to the test 

command.  What do I do?  

 

 

In the Windows Control Panel, click Device Manager.  Then, check to see if there are any 

devices marked with a yellow exclamation point. Fix all items in Device Manager that are 

marked with a yellow question mark, as there may be driver conflicts preventing the USB 

subsystem or the U60 DIN Network Interface from functioning properly. If the Device 

Manager lists Echelon USB Network Interface under the Ports (COM & LPT) heading, open 

the USB Network Interface item.  If the status indicates that the driver is not working 

properly, first try repairing the OpenLDV software. If that doesn’t work, download the latest 

version of the OpenLDV driver from Echelon’s web site. Both of these options are described 

above.  

 

Unplug and re-insert the U60 network interface.  

 

If the Device Manager does not list Echelon USB Network Interface under the Ports (COM & 

LPT), check 

www.echelon.com/downloads

 for an updated version of the OpenLDV driver. 

 

3. I opened the L

ON

W

ORKS

 Interfaces application in the Windows Control Panel and there 

is not an entry for the U60 in the interfaces pane, but the Echelon USB Network Interface 

is listed in the Ports (COM & LPT)

 

section of the Device Manager.  What do I do?  

 

 

Open the Device Manager, then expand the Ports (COM & LPT) item and double-click 

Echelon USB Network Interface to open the Properties dialog. Re-check the L

ON

W

ORKS

 

Interface application in Control Panel.  The missing entry should have been re-created.  

 

In the L

ON

W

ORKS

 Interfaces Control Panel application, try selecting 

View

->

Refresh

 from 

the main menu, or by pressing 

F5.
