Lightweight mouse configurator for Logitech HID++ devices
Maps hardware-level mouse controls: button remaps, scroll modes, thumb-gesture assignments, and per-application profiles. Mushak, from Divyang Chauhan, targets owners of Logitech MX Master series who want advanced customization without background services. The app runs in the system tray, offers a native GUI written in Rust, and emphasizes local operation with no telemetry. It supports Bluetooth and Logitech Unifying receiver connections, and keeps a tiny memory footprint for continuous use.
What does the app actually change on the device?
Mushak writes configuration directly to Logitech HID++ mice, exposing button remapping for back, forward, middle, and thumb buttons and letting you assign keyboard shortcuts, media keys, or custom combos. It also configures scroll behaviour such as ratchet, free-spin, and SmartShift, plus high-resolution scrolling and inversion. Per-application profiles switch settings automatically when an active program changes, and device monitoring shows battery level and firmware information in the GUI.
Does it slow down your system during normal use?
System impact is intentionally minimal: the resident process uses roughly 1.5 MB of RAM, and the tool is written in Rust to limit runtime overhead. It sits in the system tray without running telemetry or remote services, so background CPU and network activity remain negligible. That low footprint makes continuous operation practical on a desktop without affecting typical workflows or active applications.
Is the tool safe to run on a production machine?
Security and privacy are explicit design points. The app contains no telemetry, analytics, or remote dependencies, and it operates locally, reducing external attack surface. The developer recommends not running Mushak alongside Logitech Options, Options+, or G HUB because those programs can compete for hardware control; this advice reduces the risk of conflicting writes to the same device during configuration changes.
Do I need technical knowledge to operate it correctly?
Basic setup is straightforward but power features require attention. The native GUI exposes remap and scroll settings directly from the tray, which helps nontechnical users change common options. Advanced items, such as mapping four-direction thumb swipes or creating per-application profiles, assume the user understands shortcut assignment and profile logic. Installation is available via the Microsoft Store, Scoop, or WinGet for users familiar with those methods.
Good fit for privacy-minded power users who accept a small setup learning curve
Mushak serves power users who need direct control over Logitech HID++ mice while avoiding background analytics and heavy vendor suites. It demands caution if other Logitech software is present, but its tiny memory footprint and local operation make it reliable for daily use. Recommended.
