#Elan keyboard filter device code 19 driver
To get the name of the provider of the software package, search the internet for the service name or the driver filename, you retrieved in the previous steps. A software package might have incorrectly installed the filter drivers.If removing the filter doesn’t compromise the user experience, then this might be the best option. This will fix the code 19 issue but this is not the ideal solution because you may lose functionality of that filter driver. In this example, I removed the “testfilter” value from UpperFilter and rebooted the system. Edit the UpperFilters or LowerFilters registry entry and remove the service that’s broken and reboot the system.In this case, there is no matching service for the “testfilter” UpperFilter value.Īfter you have identified the class filter that’s causing the issue, there are two ways you can resolve the issue. If the service is not found in the registry or the driver file is not found, then the device fails with code 19 error. If the service exists, determine whether the driver file exists in the path specified by the ImagePathentry.į. In this image, the mouclass service exists and you can see service details on the right side.Į. For each value listed in UpperFilters, determine whether a matching service key exists in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services registry key. There might be more than one service listed as filters as shown in this image.ĭ. In the preceding image, the value “mouclass” value indicates the name of service. Check whether the registry key has any UpperFilters or LowerFilters entries. For each GUID see if the class name matches the one you noted in the previous step.Ĭ. Find the class key in the registry by walking the list of GUIDs under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class. On the Details tab, get the class name of the device as shown in this image for the HID-compliant mouse device:ī. In Device Manager, right-click the device node showing the error and select Properties. Determine whether a class filter driver is causing the issue.Ī.If the issue is not fixed, go to the next step. If the error code 19 issue is caused by a device filter driver, then reinstalling the driver might resolve the issue.
