What is the make of your computer and have you checked your computer support site for that driver ?

No L20 ???

That could be your chipset or video drivers you may need to download.

Have a look in Device Manager/View/Show hidden devices and look for any yellow alerts with it connected.

I do not have any "Warnings"
All drivers Update (Latest)

The camera NIKON L20 works when connected!

But I only say that I have only USB connected (camera disconnected)
Maybe can ignore this message???

[Boggin]

Could it be a problem with the cable ?

Going back to your edited Reply #2 - I would contact Nikon to see if they have any drivers for your model as it may have been discontinued.

[makinero]

Probably not detect a device that is simply disconnected,
USB cable I plugged all the time even if the camera is not connected

Note:
Nikon Transfer 2014 Software Discontinued

They must have a Contact us link on their website so I'd still contact them as they may be able to supply you with a legacy driver.

What does Device Manager display ?

[makinero]

The camera does not require drivers
after connecting everything works.

[Boggin]

So do you get an error code with the error message ?

[makinero]

Event Viewer:

Description: There was an error in the at least one of the user-mode drivers. Service process has been completed. This may cause temporary interruption of access to the device.

I'm using OS Windows 7 !!!

Maybe Windows Updates - something change in the system?

[Boggin]

If you are still getting the error, first unplug the USB cable to see if it continues, but you can also run Driver Verifier.
