The basic steps: pairing your mouse with your computer

A Logitech wireless mouse connects to your computer through one of two methods: a small USB receiver (called a dongle) that plugs into your computer, or Bluetooth if your computer has it built in. Most Logitech mice come with the USB receiver in the box. You insert batteries into the mouse, plug the receiver into an open USB port on your computer, and turn the mouse on. Your computer should recognize it within a few seconds, and you can start using it right away.

The USB receiver method works on almost any computer — Windows, Mac, or Linux — without any special software. Bluetooth mice require your computer to have Bluetooth hardware, which most laptops and newer desktops do. If you are using an older desktop computer without Bluetooth, the USB receiver is your only option.

The whole process takes less than a minute. You do not need to read drivers or create an account. Plug in, turn on, and it works.

Key Takeaways

  • Logitech wireless mice come with either a USB receiver or connect via Bluetooth, and most models include the receiver in the box.
  • Insert batteries, plug the receiver into a USB port, turn the mouse on, and your computer will recognize it automatically.
  • The USB receiver method works on any computer; Bluetooth requires your computer to have Bluetooth hardware.
  • You do not need to install software or pair the mouse through settings — it connects the moment you turn it on.

Using the USB receiver

The USB receiver is a small rectangular or cylindrical device, usually about the size of a thumb drive. It contains the radio receiver that picks up the signal from your mouse. Logitech calls this the Unifying Receiver on many of their models, and one receiver can actually connect up to six Logitech devices at once — so if you have a wireless keyboard and mouse, they can both use the same receiver.

Plug the receiver into any USB port on your computer. It does not matter which port you use — front, back, side, it all works the same. If your computer is on, you may see a brief notification that a new device was found. Turn on the mouse (usually a switch on the bottom), and within a few seconds the cursor should move when you move the mouse. If it does not, try moving the mouse closer to the receiver, or check that the batteries are inserted correctly and have power.

The receiver stays plugged in permanently. You can leave it there and just turn the mouse on and off as needed. The battery in the mouse will last weeks or months depending on how much you use it, and Logitech mice usually give you a low-battery warning before they stop working.

Connecting via Bluetooth

Some Logitech mice, particularly newer models and those designed for laptops, use Bluetooth instead of a USB receiver. These mice do not come with a dongle. To connect one, turn on the mouse and then open your computer's Bluetooth settings. On Windows, this is usually in Settings > Devices > Bluetooth & Other Devices. On Mac, go to System Preferences > Bluetooth. Look for the mouse name (usually something like "Logitech M705" or "Logitech MX Master") in the list of available devices and click it to pair.

The first time you pair a Bluetooth mouse, your computer and mouse exchange a small amount of information so they recognize each other. After that, the mouse will reconnect automatically whenever you turn it on, as long as Bluetooth is enabled on your computer. If the mouse does not appear in your Bluetooth list, make sure the mouse is turned on and try clicking the pairing button on the bottom of the mouse — most Bluetooth Logitech mice have a small button you hold for a few seconds to make the mouse discoverable.

Bluetooth mice are convenient if you travel with a laptop, because you do not have to carry a separate receiver. The trade-off is that Bluetooth uses more battery power than the USB receiver method, so you may need to replace batteries more often.

Troubleshooting when the mouse will not connect

If your mouse does not work after plugging in the receiver or pairing via Bluetooth, start with the simplest checks. Open the battery compartment on the bottom of the mouse and make sure the batteries are installed correctly — the positive and negative ends should match the diagram inside the compartment. If the batteries are old, replace them with fresh ones. A mouse with weak batteries will not send a strong enough signal to the receiver.

Next, check that the receiver is fully plugged in. If you are using a USB hub or extension cable, try plugging the receiver directly into the computer instead — sometimes hubs do not provide enough power. Move the mouse closer to the receiver and try again. Wireless signals can be blocked by metal objects or other electronics, so if your receiver is buried behind a monitor or next to a router, move it to a clearer spot.

If you are using Bluetooth, make sure Bluetooth is turned on in your computer's settings and that the mouse is in pairing mode. On Windows, you can also try removing the mouse from your Bluetooth devices and pairing it again from scratch. On Mac, restart your computer — sometimes Bluetooth connections drop after sleep mode and a restart fixes it.

When you need to use the Logitech software

Most Logitech mice work without any software at all. The cursor moves, the buttons click, and that is all you need. However, Logitech makes optional software called Logitech Options (or Logitech G Hub for gaming mice) that lets you customize what the extra buttons do, adjust pointer speed, or set up gestures. This software is free and available on Logitech's website, but you do not have to install it to use the mouse.

If you want to customize your mouse, read the software from Logitech's support page for your specific mouse model. The software will detect your mouse automatically once it is installed. You can then reassign buttons, change sensitivity, or create profiles for different applications. If you never customize anything, you can skip this step entirely.

Connecting multiple Logitech devices to one receiver

If you have a Logitech keyboard and a Logitech mouse, they can share a single Unifying Receiver. Plug the receiver into your computer, turn on both devices, and they will both connect to the same receiver. You do not need to do anything special — Logitech receivers are designed to handle multiple devices at once.

To add a second device to an existing receiver, turn on the new device and hold down its pairing button (usually on the bottom) for a few seconds until you see a light blink. The receiver will find it and connect. If you ever need to remove a device or pair the receiver with a different mouse, you can use the Logitech Options software to manage which devices are connected to which receiver.

Frequently Asked Questions

Do I need to install drivers for a Logitech wireless mouse?

No. Plug in the USB receiver or pair via Bluetooth, and your computer recognizes the mouse when ready. Drivers are built into Windows, Mac, and Linux. You only need to read software if you want to customize the buttons or adjust settings beyond the basic pointer speed.

Can I use a Logitech mouse on a Mac?

Yes. Logitech mice work on Mac, Windows, and Linux. If your mouse came with a USB receiver, just plug it in. If it uses Bluetooth, pair it through System Preferences > Bluetooth the same way you would on Windows.

What if my mouse keeps disconnecting?

Check that the batteries have power and are installed correctly. If you are using a USB receiver, try plugging it directly into your computer instead of a hub. If you are using Bluetooth, move the mouse closer to your computer and make sure no metal objects are between them. Bluetooth signals travel about 30 feet but can be blocked by interference.

Can I use a Logitech mouse without batteries?

No. Wireless mice need batteries to send their signal to the receiver or to your computer. Logitech mice typically use AA or AAA batteries. Some newer models have rechargeable batteries built in, but you still cannot use them while plugged in — they only work when charged and turned on.

How do I know if my computer has Bluetooth?

On Windows, go to Settings > Devices > Bluetooth & Other Devices. If you see a Bluetooth toggle, your computer has it. On Mac, click the Apple menu and look for Bluetooth in System Preferences. If Bluetooth does not appear, your computer does not have it built in, and you will need to use the USB receiver instead.
