Step-by-step solutions
Check that this is the affected device
A similarly named entry may belong to another component.
Open the failing entry’s properties and confirm Code 19 under Device status. Match its name to the accessory or model you are using.
If the code differs, follow that diagnosis before removing drivers. Prepare the model’s official package for reinstallation without running installers from unrelated sites.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Reinstall the appropriate driver
Arrange alternative input or networking if this is an essential device.
Save work and have the compatible official driver available. Follow Microsoft’s reinstall procedure only for the entry showing Code 19.
Install the appropriate driver and check whether the device starts. Do not delete registry keys to try to complete configuration.
Still not working?
If it persists, contact Microsoft or the manufacturer with the model and reinstall result. Configuration recovery needs a specific procedure and a backup; avoid trial-and-error registry edits.
