BSOD "DRIVER_IRQL_NOT_LESS_OR_EQUAL (kbdclass.sys)" error with new Desktop Keyboard and Mouse

Hello,

Welcome to Microsoft Community.

This bug check is usually caused by drivers that have used improper addresses.

I suggest you to follow the article below and check if it helps:

Hope the above information helps. Reply with necessary information and the result to help you further.

Thank you.

Anju,

While I appreciate the same day response the link you provided left me with 2 options:

1. To check for updates which I did and was notified that my keyboard drivers were already up to date.
2. Remove the hardware... Which wont work as I need my keyboard.

I attempted to roll back my keyboard driver and still have the same problems.

I've been using my old keyboard in my attempts to make changes to the drivers but as soon as I swap the USB dongle to the new keyboard it crashes on the first few keystrokes.

As I mentioned in the original post, I uploaded the dmp files and MSINFO to the dropbox for reference.

Could you or someone reference them to identify my issue?

Is there someone who is familiar with Microsoft L5V-00001 keyboard driver issues who can assist?

Hi,

I don't believe the issue is with the keyboard.

The dump files you provided reference the WirelessKeyboardFilter.sys :

BugCheck D1, {0, 2, 1, fffff801f0122eeb}

*** WARNING: Unable to verify timestamp for WirelessKeyboardFilter.sys
*** ERROR: Module load completed but symbols could not be loaded for WirelessKeyboardFilter.sys
Probably caused by : kbdclass.sys ( kbdclass!memcpy+2b )

The WirelessKeyboardFilter.sys is from Microsoft and may have been recently updated as per the following article:

https://support.microsoft.com/en-us/kb/3152550

However another user has reported the same error in this topic and according to the dump files you both have the  WRkrn.sys (dated July 22, 2015) as a loaded driver.

The WRkrn.sys appears to be a component of Webroot SecureAnywhere.

Because of this similarity I might suggest to uninstall Webroot SecureAnywhere and see if the error resolves.

Afterwards you could reinstall Webroot SecureAnywhere using the latest version.

For security software consider using Windows built-in antivirus (Windows Defender) and firewall.

I don't see any direct evidence that it is Webroot, just so far the wrkrn.sys is a common driver in two instances so far.

In this topic it seems uninstalling Webroot seems to be working.

I am still waiting for a reply here.

The issue could be a Microsoft driver but if that was the case I would suspect more users would be reporting the same error rather than a limited number of users.

I have just experienced this same issue, but with the microsoft keyboard and mouse combo 5050.   I couldn't even get into the computer to removed webroot.  I had to removed the mouse/keyboard, then use my on screen keyboard to remove webroot.  Rebooted and now I can use the mouse and keyboard.  

Exact same problem began affecting my Windows 10 Enterprise desktop system after installing the same Microsoft Sculpt Ergonomic Keyboard with wireless (USB) connection as reported in the original post on this topic.  System works fine with USB antenna device unplugged and a wired keyboard and mouse plugged in.  

Uninstalling WebRoot followed by a full reboot did not solve this problem.

Thanks everybody for the information. Removing webroot on my machine did work as well (no longer experiencing crashes). IT is going to re-enable webroot today to debug and we are going to see if there are any file locking issues with webroot (although I think the driver sys files should be system and signed properly so they shouldn't be an issue). 

Uninstalling WebRoot followed by a full reboot did not solve this problem.

Can you check that the WRkrn.sys  is no longer "active" on the system:

Windows Key + R > type msinfo32.exe in the "Open" box > OK > Software Environment > System Drivers

In the right window under "Name" scroll down and see if WRkrn is listed and if so what is the "State" of WRkrn?
