Hello Elma,

Go to your KES policy in your security center. Select Essential Protection, then select BadUSB attack prevention. Uncheck this component and save it. Check now if keyboards are working again.

I will try, thanks

@Elma , could you please clarify from wgat version you`ve upgrded? what version is installed now?

Is it true, that BadUSB option was enabled previously?

Thank you!

I'm not sure if badusb was active formerly but I'm sure it is not active now. I have upgraded from Kaspersky 10 to 11 but I'm not sure of the exact version, I can check and inform you on monday

Hi,

I have the same issue since I’ve updated from KES 10 to 11.2.0.2254

But now I can’t get the Keyboards working again on the affected clients.

Is there a solution for this?

 

EDIT: I deactivated the according policy in KSC

Deleting the word “klkbdctl” in the UpperFilters key in:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318}

 

Delete ONLY “klkbdctl” inside the key, else it won’t work

Hey,

I have the same issue and it’s nice that i finally know a fix for it.

Anyway we have the same Problem in our Company for many devices.

Does anybody know why this problem occures and how to prevent it.

 

Thanks :)

Hallo There,

I went crazy over the same problem. I got half of the user in our company blocked  with the Keyboard, and/or any USB device connected to it, like Pistol/Scan QR reader, When we moved from the version 10 to 11.2.

At first it happened only on Dell Computers, independently if WIN 10 was up-to-date of the latest version (2004). But then it happened also on some other computers.

In some cases it was enough to update to the latest Win10 update. In others I had to reinstall Win10, I even uninstalled Kaspersky but did not work.

In order to solve the issue, at least it worked for us, we had to uninstall Kaspersky with the Remover Tool, that you find in this link: https://support.kaspersky.com/us/common/uninstall/1464.

Then reinstall Agent and then Endpoint Security for Windows.
Then reboot 2 times.
THEN IT WORKED.

Hope it helps, but KASPERSKY TEAM should look into this problem. 

Why has it happened????

Hallo Alexcad,

we already installed with setup as you mention, but it is not working.

So far, the only thing that works, in order to remove the keyboard problen, is by uninstalling the software and reinstalling it.
