Logitech G HUB is Logitech’s configuration software for its G-series gaming hardware on Windows and macOS. It detects connected mice, keyboards, headsets, microphones and racing wheels and gives each a page for assignments, sensitivity, lighting, voice processing and firmware. G HUB replaced Logitech Gaming Software (LGS) for all new devices. On installation, it can carry over macros, profiles and settings from LGS.
Home screen and device pages
Connected devices appear on the G HUB home screen as tiles or a list. Selecting one opens its page, with tabs such as Sensitivity, LIGHTSYNC and Assignments depending on the hardware. A gear icon on the device page holds firmware updates, power options and other hardware settings.
Device pages also offer presets, including effects and settings shared by other users in the Logitech community. Uploading your own presets requires signing in with a Logi ID.
For wireless gear, the Device Pairing Tool pairs a replacement USB receiver, lets two LIGHTSPEED devices share one LIGHTSPEED keyboard receiver, and pairs a mouse with POWERPLAY.
Profiles linked to games and apps
Logitech G HUB stores settings in profiles. Each game or application in the profile list can have its own profile. A mouse can therefore use one button layout in a shooter and another on the desktop. The Desktop Default profile applies elsewhere. You can duplicate or delete profiles. Blacklisting a program stops its profiles from switching in automatically.
A persistent profile overrides this switching. Choosing one under Persistent Profile in global settings applies that profile to every game and application. This continues until you set the field back to None. Assignments and LIGHTSYNC effects can also be locked separately.
Button assignments
The Assignments tab lists available commands in categories, including a Keys tab with every keyboard key. You drag an entry onto a button on the device image. The cell then shows which button it is bound to. You can bind one key to several buttons. Clicking a button offers Use Default to restore its factory function or Disable to clear it.
Macros
You create macros in the same tab under Macros. After naming a macro you choose its type: No Repeat, Repeat While Holding, Toggle or Sequence. You then add steps from Start Now. These can include keystrokes, text and actions such as Launch Application. Launch Application accepts arguments like the path of a document to open.
Some games do not let G HUB run macros. Running G HUB at the same privilege level as the game, as administrator if the game is elevated, helps in some of these cases.
KEYCONTROL on newer keyboards
On supported keyboards, such as the G915 X and G515 families and the PRO X 60, KEYCONTROL extends assignments beyond one function per key. The base layer handles plain remapping. A G SHIFT layer becomes active while you hold a G SHIFT key. That key can sit on another Logitech G device, for example a spare mouse button. Shift, Ctrl and Alt combinations add more functions while the key keeps its normal one, up to 15 per key. You can share or download whole layouts.
Mouse sensitivity
The Sensitivity tab holds the mouse’s DPI steps, which can be added or removed. On HERO 2 mice, DPI can differ between the X and Y axes, and lift-off distance and report rate are adjustable.
LIGHTSYNC RGB
LIGHTSYNC controls lighting on supported devices. You can apply preset effects, paint individual zones or keys, build custom animations, or download animations shared by other users. Reactive modes respond to keypresses, games and content. The audio visualizer drives the lighting from PC sound, and the screen sampler matches colors to pixels on the display.
On Windows 11, G HUB can hand lighting to Windows Dynamic Lighting for all or selected devices; LIGHTSYNC cannot configure a device while Windows controls it.
BLUE VO!CE microphone processing
For BLUE VO!CE microphones and headsets, such as the YETI GX, G HUB runs the mic signal through a processing chain. Input gain comes first, then an equalizer for shaping the voice or cutting clicks, then signal cleanup with noise reduction, a gate, compressor, de-esser, de-popper and limiter. An Effects stage adds pitch shift, formant shifting and reverb delay. You can browse and apply stock and community presets.
A Sampler tool plays or records audio through the processed mic output and can trigger clips from hotkeys.
On-board memory for mice
With On-Board Memory mode switched on in a mouse’s gear menu, G HUB writes its customizations to the mouse. This keeps them with the device. Wireless mice need their cable or receiver connected to set this. Macros in this mode are limited to No Repeat macros containing text and modifiers; Repeat While Holding, Toggle and Sequence macros only work when the mode is off.
Game library
You can enable a Games tab from the Beta Features page in settings. It scans platforms such as Steam, GOG and WeGame and gathers their games into one library. You can sort games by platform, progress and Logitech G features such as TRUEFORCE. You can also launch them from G HUB with settings matched to the gear you own.
