Common causes include incorrect or corrupted registry entries related to UpperFilters and LowerFilters values. Additionally, software conflicts—often arising from recent driver installations or updates, or programs like iTunes or CD/DVD burning software—can also lead to this problem. Now that you know the causes, let’s discuss the solutions.
1. Reboot your System
Sometimes, just restarting your computer can fix temporary issues by refreshing the system’s registry and reloading drivers. This ensures all hardware devices are reinitialized, which can resolve minor problems without needing more steps. This process effectively gives your system a fresh start, clearing minor issues that may have arisen from recent changes or updates.
2. See if iTunes is Causing the Problem
iTunes can change registry settings for media devices, causing the Code 19 error. Checking or reinstalling iTunes can fix these settings and remove any conflicts.
3. Delete UpperFilters and LowerFilters from the registry
Corrupted or conflicting registry entries, like UpperFilters and LowerFilters, can interfere with how Windows talks to hardware devices. Removing these registry values can fix the setup, helping the device to be correctly recognized and used by the system.
