MyHUB

MyHUB is a lightweight peripheral manager for Windows and Linux that runs in the tray, starts with the system, and talks to devices directly. It replaces vendor suites for the settings people change every day: DPI, report rate, onboard profiles, noise cancelling, equalizer and battery status. Two devices are supported: the Logitech G502 X LIGHTSPEED mouse over HID++ 2.0, with no Logitech G HUB required, and the Sony WF-C710N earbuds over Bluetooth RFCOMM, with no Sony Headphones Connect phone app required.

Status

Version 0.1.0, under active development. Windows is the tested platform. A Linux build for Kubuntu (KDE Plasma) is planned and not yet tested; the Bluetooth transport for the Sony earbuds is Windows only for now.

What works on the G502 X LIGHTSPEED

Area	Behaviour
Connection	Detects the receiver, follows the mouse when it is switched off or wakes up, and rediscovers features at runtime
Battery	Live percent, level and charging state from feature 0x1004, updated from the mouse's own events
Profile mode	Edits DPI levels, default and shift DPI index and report rate of the MyHUB profile and saves them to the mouse; buttons, profiles and lighting keep working on the mouse
Live state	DPI and profile changes made with the mouse buttons appear in the app immediately
App control mode	The app sets DPI and report rate at runtime; the mouse DPI buttons step through the profile levels via feature 0x8110
Start up	Optional launch at login, hidden in the tray, restoring the last mode and DPI

Button assignments are shown read only.

What works on the Sony WF-C710N

Area	Behaviour
Connection	Finds the paired earbuds, connects to the control channel, and reconnects on its own after the earbuds go back in the case
Battery	Left, right and case percent with charging state, updated from the earbuds' own notifications and shown in the tray menu
Sound mode	Noise cancelling or ambient sound, ambient mode normal or voice, ambient level 1 to 20
Equalizer	Preset selection, and the five bands from 400 Hz to 16 kHz plus Clear Bass on a -10 to +10 dB scale, saved to the Custom equalizer
Settings	Sidetone on or off, multipoint on or off (the earbuds reconnect after a multipoint change), codec and firmware shown

Every change is read back from the earbuds before the app reports it as saved.

Common to both devices

Tray flyout with a device switcher, main window, tray menu with the battery of each device, light and dark themes, Polish and English. Device changes are off until "Allow changes on the device" is switched on in Settings.

Hardware safety

The app never touches firmware, and every request passes a per device allowlist before a byte is sent.

G502 X: feature indexes are resolved at runtime from the Root feature. Firmware update features and hidden vendor features are blocked outright. Flash writes are limited to DPI levels, DPI indexes and report rate in user profile sectors, run as whole sector writes with a backup to disk first, then a byte for byte read back and CRC check, with an automatic restore on mismatch. ROM profile sectors are never written. MyHUB uses its own HID++ software ID, so it can run next to G HUB without taking its replies.

WF-C710N: the supported functions and their variants are read from the earbuds at connect time. Firmware update, factory reset, factory power off and paired device management commands are blocked outright. Reads are the default; setting changes and the multipoint change, which disconnects the earbuds for a moment, each need their own gate, opened only for that one request. Multipoint is changed only after the user confirms it in the app.

Architecture

Path	Contents
crates/hidpp	HID++ protocol: frames, feature table, safety policy, CRC, onboard profile parsing and sector patching. No I/O
crates/transport	hidapi transport and HID++ session (Windows collections, Linux hidraw)
crates/mdr	Sony headphone control protocol: frames, acknowledgement and sequence handling, supported function table, messages, safety policy. No I/O
crates/rfcomm	Bluetooth RFCOMM byte link (Windows Winsock; Linux not yet implemented)
crates/core	Types shared between the backend and the UI
crates/devices/logitech-g502x	G502 X module: snapshot read, detail mapping, runtime settings, profile writes, button spy, hw_probe tool
crates/devices/sony-wf-c710n	WF-C710N module: session, snapshot read, detail mapping, setting writes with read back, mdr_probe tool
src-tauri	Tauri 2 app: one worker per device, tray, flyout, settings, commands
src	React and TypeScript UI

Stack: Tauri 2, Rust (edition 2024), React 19, TypeScript, Vite, Tailwind CSS v4, hidapi, windows-sys.

Development

Requirements: Rust stable (MSVC on Windows), Bun, Node 24.

bun install
bun run tauri dev

Checks:

cargo test --workspace
cargo fmt --all --check
cargo clippy --workspace --all-targets -- -D warnings
bun run typecheck

Tests run against recorded device frames and mocks only, and no test opens a real device. Two tools read a connected device without writing anything: cargo run -p logitech-g502x --example hw_probe -- state for the mouse and cargo run -p sony-wf-c710n --example mdr_probe -- state for the earbuds. Browser previews of the UI without a device: ?demo=g502x, ?demo=sony and ?demo=all on the Vite dev server.
