Corsair’s 2.4 GHz wireless mice are normally paired with their USB receiver at the factory. If the connection is lost, the receiver is replaced or a firmware change leaves the mouse disconnected, iCUE includes a USB Wireless Receiver Pairing function for supported models.
The most important preparation step is to use the correct wireless mode. Corsair’s current instructions specifically say the mouse must be in 2.4 GHz mode rather than Bluetooth for receiver pairing. Bluetooth can work perfectly while the USB receiver remains unpaired because those are two separate radio paths.
Connect the mouse and receiver directly to the PC
Plug the wireless USB receiver into the computer and connect the mouse by USB cable if your model supports wired data. Avoid hubs for the initial pairing attempt. A direct connection makes it easier for iCUE to detect both devices and reduces the chance that a dock or hub interrupts a firmware or pairing transaction.
Open iCUE and wait for the mouse and receiver to appear. If the mouse only shows while connected by cable, that is expected before a broken wireless pairing has been repaired.
Use USB Wireless Receiver Pairing in iCUE
On Corsair’s current iCUE workflow, hover over the wireless mouse on the home screen and open Device Settings. Find USB Wireless Receiver Pairing and click Pair. Connect the mouse and receiver as instructed, then start the process.
- Open iCUE.
- Open Device Settings for the wireless mouse.
- Select Pair beside USB Wireless Receiver Pairing.
- Connect the mouse to the PC with a data-capable USB cable.
- Connect the mouse’s compatible wireless USB receiver.
- Make sure the mouse is set to 2.4 GHz, not Bluetooth.
- Start the pairing process and wait for iCUE to report success.
Once pairing is complete, unplug the mouse cable and confirm that the mouse continues to work through the receiver.
Some Corsair models use a button combination
Not every wireless Corsair mouse enters pairing mode in exactly the same way. Corsair documents model-specific steps for products such as the Katar Pro Wireless, which uses the DPI button while the power switch is moved to 2.4 GHz. Other models rely more heavily on the iCUE wizard while connected by cable.
If iCUE asks you to hold a button or power-cycle the mouse, follow that on-screen instruction. Do not borrow a button sequence from a different Corsair model unless the support page confirms it applies.
What if the receiver is a SLIPSTREAM Multipoint receiver?
Corsair’s SLIPSTREAM Multipoint feature can pair compatible devices of different types to one receiver, such as a keyboard and mouse or a headset and mouse. That is a separate configuration from simply restoring a one-to-one mouse receiver pairing.
If you are intentionally setting up Multipoint, select the wireless receiver in iCUE, open Connections and use Pair. Corsair requires a compatible device combination and recommends connecting the devices directly to the PC during the setup process. Do not assume a random spare SLIPSTREAM receiver can accept any two mice; Corsair’s Multipoint rules do not allow two devices of the same type in the supported combinations documented by the company.
If iCUE cannot see the mouse or receiver
Move both devices to direct USB ports, restart iCUE and try again. Use a known-good data cable for the mouse. A cable that only supplies power can make the mouse charge while preventing iCUE from accessing the device for pairing.
Check for firmware updates in iCUE. If a pairing wizard stops partway through, restart iCUE and repeat the process after both devices are detected. Corsair also recommends avoiding USB hubs during setup and firmware work.
Pairing succeeds but wireless performance is unstable
After the mouse is paired, test it without the cable. If clicks or movement stop intermittently, move the receiver closer to the mouse and away from the rear of a metal PC case or a cluster of high-speed USB devices. Also check battery charge and test another USB port.
Use Bluetooth only as a comparison. If Bluetooth is stable but 2.4 GHz repeatedly disconnects, focus on the receiver, USB connection, receiver placement and the 2.4 GHz pairing state. If both wireless modes fail, the mouse itself becomes a stronger suspect.
How to know the pairing is really fixed
A repaired pairing should survive a normal restart and a receiver reconnect. Test the mouse for several minutes, unplug the receiver, reconnect it and confirm that the mouse returns without opening iCUE’s pairing wizard again.
If the association is repeatedly lost, test the receiver on another computer. A second system helps separate a damaged receiver from iCUE installation problems or USB instability on the original PC.
