Note

Fix G309 LightForce mode detection and extended-DPI writes in Logitech HID++ driver

• Reclassifies the G309 as a non-power-only model and adds a new exception set so LightForce mode is exposed even without live lift-off control; the G305 stays power-only (hidpp.ts)
• Adds hasLightforceModeControl, which requires non-power-only status, no analog buttons, and either live lift-off control or membership in the new G309 exception set
• Fixes LogitechHidppClient.setDpi and setLiftOffDistance to read extended-DPI capabilities first and write zero for unsupported Y-axis DPI and lift-off fields, instead of copying unsupported values; the DPI confirmation check now only compares Y when separate axes are supported
• HID++ rejection messages now include the feature index and function ID of the failed request
• Updates G309 testing notes in logitech-testing.md and adds dev dependency @types/node
• Behavioral Change: G309 mice now report LightForce mode in status; setDpi writes a different byte layout for devices without separate Y-axis or lift-off support

^{Macroscope summarized 227927c.}

Summary by CodeRabbit

• New Features
  • LightForce mode is available for the G309, including when lift-off controls are unavailable.
• Bug Fixes
  • DPI updates now work correctly on devices without separate X- and Y-axis settings.
  • Lift-off and gaming-surface controls are shown only when supported by the device, helping prevent unavailable controls from appearing.

Walkthrough

The Logitech HID++ driver updates model-specific control visibility, capability-aware DPI and lift-off writes, and rejection error details. Tests and documentation reflect these changes. The development dependencies add @types/node.

Changes: Logitech HID++ behavior

Layer / File(s)	Summary
Model-specific control visibility src/drivers/logitech/hidpp.ts, src/drivers/logitech/hidpp.test.ts, docs/logitech-testing.md	The G309 can expose LightForce mode without live lift-off control. Gaming-surface visibility remains gated by live lift-off control and power-only status. Tests and documentation reflect the control behavior.
Capability-aware DPI writes src/drivers/logitech/hidpp.ts, src/drivers/logitech/hidpp.test.ts	DPI and lift-off writes account for separate-axis and lift-off capabilities. A test checks that a device without separate-axis support receives a zero Y-axis value.
HID++ rejection details src/drivers/logitech/hidpp.ts, src/drivers/logitech/hidpp.test.ts	Rejection messages include the matched feature and function identifiers. A test checks the identifiers in an invalid-argument rejection.

Development dependency

Layer / File(s)	Summary
Node.js type definitions package.json	Adds @types/node as a development dependency.

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 2 files. (1 skipped: 1 unsupported.)

Full details: Title check

Explanation

The title "fix(notlokry): G309 Lightforce switches and DPI" names the G309 model, LightForce switch support, and DPI handling. The raw summary and PR objectives confirm these are the main changes: LightForce mode support for the G309 via hasLightforceModeControl, and DPI writes that preserve Y DPI only when separate axes are supported. The title is specific and short. Its scope is slightly narrow because the PR also covers lift-off writes, HID++ error detail, and hardware-testing docs. Those are secondary to the title's main subject. The title uses a conventional commit prefix with a scope, which is acceptable.

Approvability

Verdict: Approved at 227927c

Macroscope's review found this PR approvable — The PR makes localized Logitech HID++ fixes: it exposes the verified G309 LightForce control and writes only supported extended-DPI fields, with focused tests and documented hardware validation. Other changes are limited to diagnostics, documentation, and development dependencies.

Notes:

• Your repo's Minimum Blocking Severity is Off, so correctness findings do not automatically block approval.
• No code objects were reviewed. Approvability was decided on eligibility alone.
