driver missing Dell Latitude E5540

The screen does not tell us what it is.

Is Audio working correctly?
Is Video working correctly?

Open Network devices - is one missing that you can see?

From there, look in Dell Driver Support and see what drivers are available. Look for one (or two) you do not have on your machine.

Then see if Dell has a driver updater and run that to flush out missing drivers.

Audio and Video is fine, I do not see any missing NIC drivers, I already run the Dell driver updater

right click on it and select properties, then select Driver tab, then update driver,

Bring up Device Manager per your image above.

Right click on the missing device.

Select Properties from the drop-down menu.

On the new window, click Details.

Record the VEN and DEV contents of the Device Instance ID and let us know what they are.  This identifies the manufacturer and device.

Also try just removing the errant driver (uninstall it from Device Manager), shut down (power off), start up, and see what you are presented with in terms of drivers to install.

also,
Right click on the missing device.
 Select Properties from the drop-down menu.
 On the new window, click Details.
select hardware IDs
copy what is in under "Value" and paste it here.

Go to Dell support website for your model

http://www.dell.com/support/home/us/en/4/product-support/product/latitude-e5540-laptop/drivers

Under Chipset section download and install
Intel Chipset Device Software
and
Intel USB3.0 xHCI Driver

Install both

This will be the correct driver for your network devices.

update all drivers from the manufacturer site

Can't seem to find: Intel USB3.0 xHCI Driver?
can you help?

click on this ">" left side of chipset on that page:

thanks Tom
It's a Windows 10 that is why I do not see the USB driver, that's probably why I can't find a driver for this unknown as well

You still haven't identified the device for us.  Without that information, any information we give you is speculation.  Please post the Device Instance ID per the earlier request.

thanks
