Diagnostic visibility · current policy

Technical diagnostics are aggregated on this page so driver authors and tool builders can compare what multiple testers saw, including Windows and Linux runs for the same VID:PID. They use closed result names and path-redacted errors; the private response-notes field includes typed text and any Linux probe-measured motion.

What's NOT on this page

The one private field

The per-effect responses[].notes field stays off this page. It can contain optional typed text and Linux probe-measured motion. Capability flags, supported effects, OS breakdown, chip labels, result codes, failed effects, and run errors can be published in aggregate or as a latest-per-platform snapshot.
