A peripheral or feature that disconnects and reconnects on a computer is usually a power-management or driver-timeout setting, not failing hardware. For macOS app privacy permissions, first inspect Privacy & Security and test the app immediately after granting one permission.
What this covers
- macOS app privacy permissions with this exact failure state
- Diagnosis across system permission versus app selection, managed policy and relaunch requirement

ReversibleNote whether the drop correlates with sleep/wake, a specific USB hub, or sustained heavy use. Expected behavior: grant the selected app only the camera, microphone, files, accessibility or screen access it needs.
Isolate the component boundary
ReversibleInspect Privacy & Security and test the app immediately after granting one permission. Test the device on a direct port with no hub, and disable USB selective suspend for that port. Boundary to separate: system permission versus app selection, managed policy and relaunch requirement.
Correct only the proven cause
ReversibleGrant the narrow permission and relaunch/update the app. Disable the power-management setting that turns the device off to save power, or update the controller driver.
Verify and stop safely
ReversibleRun the device under the same load that triggered the drop for at least 30 minutes. Do not grant Full Disk Access or Accessibility to an untrusted app.
