To pair a dongle with a mouse, plug the USB receiver into your computer and turn the mouse on; they are almost always pre-paired at the factory and will connect automatically. If they do not, you must use the mouse manufacturer's official connection utility, as there is no universal manual pairing process for wireless dongles.
What you need to know before you pair a dongle with a mouse
Unlike Bluetooth, where you search for devices and select them, a wireless mouse that comes with a USB dongle is typically pre-paired from the factory. This means the dongle and mouse are coded to each other and should work the moment the dongle is plugged in and the mouse is turned on. If you are expecting a multi-step pairing process, you may be looking for Bluetooth instructions instead. For most users, the connection is instant and requires no action beyond inserting the receiver.
Step 1: Check that the dongle and mouse belong together
Wireless dongles are uniquely coded to their specific mouse model. You cannot mix and match a dongle from one mouse with a different mouse, even from the same brand. To confirm they are a pair, check the model numbers printed on the underside of the mouse and on the dongle itself. If the numbers do not match, the devices will not connect. If you have lost the original dongle, you must purchase a replacement receiver designed for that exact mouse model.
Step 2: Plug the dongle into a USB port and turn on the mouse
- Insert the dongle into an available USB port on your computer. If your computer only has USB-C ports, use a USB-C-to-USB adapter or a USB-C hub. Some dongles have a small LED that lights up or clicks when properly inserted and receiving power.
- Turn on the mouse using its power switch, usually located on the bottom or side.
- Move the mouse and check if the cursor responds. The connection should be automatic.
If the dongle sticks out and risks damage on a laptop, consider using a USB extension cable to place it in a safer location. If you are using an iPhone, Apple supports pointer devices through AssistiveTouch. Plug a wired mouse, or a Bluetooth device, into a Lightning or USB-C port using an adapter if needed, then go to Settings > Accessibility > Touch > AssistiveTouch > Devices > Bluetooth Devices and select the device. This path is for direct wired or Bluetooth connection, not for pairing a mouse to a USB dongle specifically. For Android and Samsung devices, you can use a mouse through Bluetooth settings or by connecting a USB receiver via a compatible USB-C-to-USB adapter, USB-C hub, or supported DeX accessory. On Samsung, in DeX mode, go to Settings > Connected devices > Samsung DeX > Mouse and trackpad > More settings to adjust pointer behavior.
Step 3: What to do if the mouse doesn't connect automatically
If the mouse does not respond after plugging in the dongle and turning it on, the automatic connection failed. Do not look for a physical “pairing button” on the dongle or mouse, most wireless dongles do not have one. The mouse's pairing mode typically has a time limit, so proceed to the next step promptly. The only reliable manual method is to download the official connection utility from the mouse manufacturer's website (Logitech, Razer, Corsair, etc.). This software will detect the dongle and guide you through re-pairing it with your specific mouse. If the utility cannot find the dongle, try a different USB port, restart your computer, and ensure the mouse has fresh batteries.
Frequently Asked Questions
Can I pair any dongle with any mouse?
No. Dongles and mice are almost always sold as matched pairs. The dongle is coded to communicate only with its specific mouse model. Using a dongle from a different mouse will not work, even if both are from the same brand.
Why is my dongle not connecting to my mouse?
First, confirm the dongle and mouse are a matching pair by checking their model numbers. Ensure the dongle is fully inserted into a working USB port and that the mouse has power (fresh batteries or a charged battery). If they still do not connect, use the manufacturer's connection utility to re-pair them.
What is a Bluetooth dongle, and is it the same as a mouse receiver?
A Bluetooth dongle is a generic adapter that adds Bluetooth capability to a computer. It is not the same as a dedicated wireless mouse receiver. A mouse receiver is pre-paired to one specific mouse, while a Bluetooth dongle allows you to pair any Bluetooth mouse through your device's Bluetooth settings.
How do I connect a wireless mouse to a Chromebook?
If your mouse uses a USB receiver, plug the dongle into a USB port on the Chromebook. Turn the mouse on, it should connect automatically. If the mouse is Bluetooth, put it in pairing mode, then click the clock area, select the gear icon, go to Bluetooth, and choose the mouse from the list.
Can I pair multiple mice with a single dongle?
Most standard mouse dongles support only one mouse at a time. Check your dongle’s specifications to confirm.
How do I know if my dongle is compatible with my mouse?
Check specifications for supported wireless protocols (Bluetooth or RF), frequency ranges, and pairing procedures.
