Wired and wireless mice both plug in the same way — through a USB port on your computer
A wired mouse connects directly to your computer with a cable. A wireless mouse uses a small receiver (called a dongle) that you plug into a USB port instead. Either way, your computer recognizes the mouse automatically in most cases, and you can start using it right away. The main difference is that a wireless mouse needs batteries or charging, while a wired mouse draws power from the USB connection itself.
Before you plug anything in, locate a USB port on your computer. On a desktop, these are usually on the back of the tower or on the front panel. On a laptop, they're on the sides. USB ports are small rectangular openings, and most computers have at least two or three of them.
Key Takeaways
- Wired mice plug directly into a USB port; wireless mice use a small receiver that plugs into a USB port instead.
- Your computer will recognize most mice automatically — you do not need to install software or drivers in advance.
- If your mouse does not work after plugging it in, try a different USB port or restart your computer.
- Wireless mice need batteries or charging, while wired mice draw power from the USB connection.
Connecting a wired mouse
Plug the cable end of the mouse into any available USB port on your computer. Push it in firmly until you hear or feel a small click — the connector should sit flush with the port. Your computer will detect the mouse within a few seconds.
Move the mouse around on a flat surface to test it. The cursor on your screen should move in the same direction. If it does not, try unplugging the mouse and plugging it into a different USB port, then restart your computer if the cursor still does not move.
Connecting a wireless mouse
Wireless mice come with a small USB receiver. Insert batteries into the mouse first (check the battery compartment on the bottom), then plug the receiver into a USB port on your computer. The receiver is usually very small — about the size of a USB stick — and will stay plugged in permanently.
Most wireless mice turn on automatically when you insert batteries. Move the mouse to test the connection. If the cursor does not move, check that the batteries are inserted correctly and have power. Some wireless mice have a small button on the bottom that you press to pair the mouse with the receiver — check the instructions that came with your mouse if movement does not work right away.
What to do if your mouse is not working
If you plugged in the mouse and the cursor does not move, first try a different USB port. Some ports on older computers or laptops may not work properly. Unplug the mouse, wait a few seconds, and plug it into another port.
If that does not help, restart your computer with the mouse already plugged in. During startup, your computer loads drivers — the software that lets it talk to the mouse. A restart often fixes connection problems.
For wireless mice, also check that the batteries are fresh and inserted in the correct direction (the + and − symbols inside the battery compartment show which way they go). If the receiver has a small light on it, that light should be on or blinking. If it is not, the batteries may be dead.
USB ports and compatibility
Almost all mice use USB-A ports, which are the standard rectangular ports found on every computer made in the last 15 years. If your computer has only USB-C ports (smaller, oval-shaped), you will need a USB-C to USB-A adapter, which costs a few dollars and is widely available.
Mice are plug-and-play devices, meaning they work with any computer — Windows, Mac, or Linux — without needing special software. Your operating system already has the basic drivers built in. Some gaming or specialty mice come with software you can install to customize buttons or sensitivity, but that is optional.
Caring for your mouse
Keep the mouse on a clean, flat surface. Dust and debris can get stuck under the sensor on the bottom, which makes the cursor jump or move erratically. Wipe the bottom of the mouse with a dry cloth every few weeks if you use it daily.
For wireless mice, replace batteries when the cursor starts moving slowly or erratically — that is usually the first sign that power is running low. Keep the receiver within a few feet of the mouse for the best connection. Walls and metal objects can weaken the wireless signal, so if your mouse stops responding, try moving the receiver closer or removing obstacles between it and the mouse.
Frequently Asked Questions
Can I use multiple mice on one computer?
Yes. Plug in a second mouse and your computer will recognize it automatically. Both mice will control the same cursor, so you can use whichever one you pick up. This is useful if you want a wired mouse at your desk and a wireless one for travel.
Do I need to install drivers for my mouse to work?
No, not for basic use. Your computer has built-in drivers for standard mice. Some gaming mice or specialty mice come with software you can download from the manufacturer's website if you want to customize buttons or sensitivity, but the mouse will work without it.
Why is my wireless mouse cursor jumping around?
The batteries are probably low. Replace them with fresh ones. If that does not fix it, try moving the receiver closer to the mouse or removing obstacles like metal objects or thick walls between them. Dust under the sensor can also cause jumping — wipe the bottom of the mouse with a dry cloth.
Can I use a mouse from one brand with a receiver from another brand?
Not usually. Wireless receivers are paired to specific mice during manufacturing. A Logitech receiver will not work with a Microsoft mouse, for example. Stick with the receiver that came with your mouse.
What if my computer does not have any free USB ports?
Buy a USB hub, which plugs into one port and gives you four or more additional ports. They cost between five and twenty dollars depending on the brand and number of ports. Plug the hub into your computer, then plug the mouse receiver (or wired mouse) into the hub.
