Keep the mouse's internal firmware current for stability and new features

Firmware is the small piece of software running on the mouse's own microcontroller — separate from the drivers or configuration apps installed on your computer. It governs low-level behavior like sensor tracking, button debounce timing, Bluetooth/2.4GHz radio stability, and battery reporting, and manufacturers periodically release updates to fix bugs or add features.

How to open Update Mouse Firmware

  1. Open the manufacturer's configuration app and connect the mouse via its cable if it has one, or ensure the wireless connection is stable and battery is above roughly 50%.
  2. Navigate to the device's settings or "About this device" page and check for an available firmware update.
  3. Start the update and leave the mouse connected and untouched until the app confirms completion — do not disconnect, put the computer to sleep, or move the mouse out of range mid-update.

What you should know

  • Firmware updates are delivered and installed through the same manufacturer software used for button and DPI customization — Logitech G HUB/Options+, Razer Synapse, SteelSeries GG, and Corsair iCUE all check for and push firmware updates automatically when the mouse is connected.
  • Keep the mouse connected (ideally with a cable, if it has one) and at a healthy battery level throughout a firmware update — interrupting the process partway through (disconnecting, running out of battery) can leave the mouse in an unresponsive state that sometimes requires a manufacturer recovery tool to fix.
  • Not every firmware release is mandatory — check the release notes in the manufacturer app; many are minor stability or compatibility fixes rather than something you'll notice day to day, but connectivity or click-latency fixes are usually worth installing promptly.
  • Some manufacturers publish standalone firmware updater tools separate from the main configuration app, intended for advanced troubleshooting or for restoring a bricked mouse to factory firmware.

Why it matters

Because mouse firmware runs beneath the OS driver layer, a firmware bug can cause symptoms — random disconnects, double-click misfires, erratic cursor jumps — that look identical to a hardware fault or a Windows/macOS driver problem, and no amount of OS-level troubleshooting fixes them; checking for a firmware update is one of the few remaining steps once basic connectivity troubleshooting is exhausted.

Best practices

  • Update firmware over a wired connection when the mouse supports one, since a dropped wireless connection mid-update is the single most common cause of a failed update.
  • Read the release notes before updating on a mouse you rely on for competitive gaming or precision work — occasionally a firmware change affects sensor behavior or click latency in ways some users prefer to avoid until reviewed.
  • Keep the manufacturer app itself updated as well, since older app versions sometimes can't detect or push the newest firmware releases.

Common problems and fixes

Firmware update fails partway through or the mouse stops responding afterward
Don't disconnect power/battery — most manufacturers provide a recovery mode (often holding a specific button combination while reconnecting) or a standalone recovery tool specifically for interrupted updates; check the manufacturer's support site for your exact model.
Manufacturer app doesn't detect any available firmware update
Confirm the app itself is on its latest version, and that the mouse is fully recognized (not just charging) — some apps only check for firmware once the device handshake completes, which can be slower over Bluetooth than a wired or 2.4GHz connection.

Tips and tricks

  • If you manage several of the same mouse model (e.g., in an office), export the firmware/config profile from one after updating and use the manufacturer app's import feature to apply it to the rest quickly.

Frequently asked questions

Can outdated firmware be a security risk?

It's uncommon but not impossible — Bluetooth firmware bugs have occasionally been the subject of security advisories, so keeping firmware current is good practice even though most updates are about stability rather than security.
