My DisplayLink device does not work at all, or I get the message "USB device not recognized", when connecting on Windows.

If your DisplayLink product does not work, has stopped working, or has never worked, follow the steps below to try and diagnose if it is a hardware problem.

Note: Unless a DisplayLink product is identified by the DisplayLink software on the USB bus, the DisplayLink UI icon will not appear in the Windows system tray (v7.9 or earlier software), or will show the DisplayLink "disconnected" icon (8.0 software onwards). The UI icon will always appear in the system tray if you are running Windows 10 Anniversary update 2016, released August 2016.

If you do not see the DisplayLink UI in the system tray, check that the device is recognised on the USB bus

If you have a product based on the DL-3xxx or DL-5xxx (USB 3.0) family, the DisplayLink UI will only appear if a DisplayLink device has been detected AND a monitor is connected to the video output. The DL-3000 family implements monitor detection and the DisplayLink UI will only be shown in the system tray when a DisplayLink device and a display is detected.

"USB Device Not Recognized" message




This is normally due to a hardware problem. The Windows PC has tried to query the USB device to find out what it is and a device has returned a corrupt message.

This is not due to a DisplayLink software or driver problem, as the OS has not even been able to recognise the device to know which driver it requires.

To solve this, try the following steps:
  1. Check other USB devices are recognised by the PC. Ensure that you are using a good quality USB cable and test again by using a different USB port on the computer.
  2. If using a USB bus powered device, make sure that the device is connected to an externally powered USB hub (the hub has a USB cable AND a power supply connected to it). This will ensure that the device is receiving enough power from the USB bus.
  3. If using a docking station, remove all other devices that may be connected to the dock and try again. This will confirm that it is not caused by another device connected to the dock.
If the problem persists, then you should contact the original manufacturer, not DisplayLink, to discuss a hardware replacement of the product.

Check the device is recognised on the USB bus


If your device does not work, the first thing to check is that the DisplayLink device has been detected by Windows. This can be done by checking that the DisplayLink device appears in Windows device manager.

To open device manager, follow the steps below:
  1. Right click on the Windows Start button
  2. Select "Device Manager" from the Menu
Make sure you have your DisplayLink product connected to the PC, and check that "USB Display Adapters" appear in the list with an item below it OR the DisplayLink device appears under "Display Adapters" Eg:


Device manager for Windows 7 to Windows 10 (2015 edition)


Device manager for Windows 10 Anniversary Update 2016 onwards

If no devices are shown, then follow the steps below to try and make the device appear in device manager.
  1. Check the DisplayLink device does not appear under "Other devices". If there is an item under "Other Devices", follow the steps below to see if it is the DisplayLink device.
  2. Unplug all cables from the device, then reconnect power (if needed) then the USB cable.
  3. Check the USB port with another device to make sure other devices are recognised.
  4. If using a Wireless USB product, ensure the wireless USB drivers are installed separately. The wireless USB link is not part of the DisplayLink technology and will need separate drivers to be installed.
  5. Check that the USB cable works with other devices.
  6. If using a USB bus powered device, make sure that the device is connected to an externally powered USB hub (the hub has a USB cable and a power supply connected to it). This will ensure that the device an receive enough power from the USB bus.
  7. Try the adapter on another computer.
If it still does not appear in device manager then you should contact the original manufacturer, not DisplayLink, to discuss a hardware replacement of the product.

If a device is shown, check the Product ID to ensure it has started up correctly.

Checking "Other Devices"


To check if the DisplayLink device has been detected as an "Other Device":
  1. Right click on the device and choose "Properties"
  2. Click on the "Details" tab
  3. Choose the Property "Hardware Ids".
  4. If the device is a DisplayLink device, you should see a value like USB\VID_17E9&PID_XXXX, where XXXX can be any hexadecimcal value (0-9 or A-F). If the VID is not 17E9, then this is not a DisplayLink device. Eg:
If the DisplayLink device is shown under "Other Devices", then Windows is not asssociating the DisplayLink USB driver with our device. Follow these steps to completely uninstall the DisplayLink software and drivers, then reinstall the latest Windows software from DisplayLink.

Check the Product ID of the DisplayLink device


If the DisplayLink device is shown in device manager, but still does not work, then the Product ID (PID) should be checked to make sure the device has started up correctly.
  1. Right click on the device and choose "Properties"
  2. Click on the "Details" tab
  3. Choose the Property "Hardware Ids".
  4. If the device is a DisplayLink device, you should see a value like USB\VID_17E9&PID_XXXX, where XXXX can be any hexadecimcal value (0-9 or A-F).

If the PID is 8060 or 8080, then the device has not booted up correctly. To recover the device:
  1. Unplug all cables
  2. Connect Power (if required)
  3. Connect the USB cable
  4. Connect the video cable
If the device continues to appear with the same PID then then you should contact the original manufacturer, not DisplayLink, to discuss a hardware replacement of the product.
