To pair a Logitech dongle, you cannot "reprogram" the receiver itself; instead, you must use Logitech's official pairing software to connect a compatible mouse or keyboard to your existing Unifying or Logi Bolt receiver. This process is often mistakenly called reprogramming, but it is simply a matter of pairing a supported device to the correct receiver type.
Can you pair a Logitech dongle?
The short answer is yes, but only with the right device and software. Logitech dongles are not reprogrammable in the broad sense; you cannot rewrite the firmware or change the receiver's core functionality. Instead, Logitech's official support documents a workflow to pair or add a supported device to an existing receiver using Logitech's pairing software or app. This is the correct method for what most users call "reprogramming" a Logitech dongle.
Understanding your Logitech receiver type
Logitech produces two main types of wireless receivers: Unifying and Logi Bolt. These are not cross-compatible. A Unifying receiver only works with Logitech Unifying-compatible mice and keyboards, while a Logi Bolt receiver only works with Logi Bolt wireless products. You can identify your receiver by its physical markings: Unifying receivers typically have an orange logo, while Logi Bolt receivers have a green logo. Logitech Unifying receivers can connect multiple compatible devices to a single receiver. Some hosts can use both Unifying and Bolt receiver types at the same time if they have two available USB-A ports. It is critical to confirm your receiver type before attempting to pair a device, as using the wrong software or device will not work.
How to pair a device to a Logitech Unifying receiver
- Plug the Unifying receiver into an available USB port on your computer.
- Install or open the Logitech Unifying Software on your computer.
- Open the software and follow the on-screen pairing flow, selecting the next or continue step as prompted.
- Keep the device you want to connect nearby and follow the prompts until pairing completes.
Only devices made for Logitech Unifying can pair with this receiver. This includes most Logitech mice and keyboards that display the orange Unifying logo.
How to pair a device to a Logi Bolt receiver
- Plug the Logi Bolt receiver into a USB port on your computer.
- Open Logi Options+ on your computer. This is the recommended app for supported Logitech devices.
- Follow the pairing flow in Logi Options+ to connect a new Logi Bolt device to the receiver.
- Keep the device close to the receiver during the pairing process.
Only Logi Bolt devices can pair with a Logi Bolt receiver. Logitech states that Bolt and Unifying devices cannot be paired to each other's receivers.
Troubleshooting pairing issues
If pairing fails, start by confirming you are using the correct receiver type for your device. Keep the device within a few feet of the receiver during pairing. Check the device's battery and ensure it is powered on. Use Logitech's supported pairing software (Logitech Unifying Software or Logi Options+) rather than the discontinued Firmware Update Tool, which Logitech no longer supports. Before making changes, consider backing up original settings (optional). If issues persist, try resetting the dongle via a physical reset button before pairing.
Frequently Asked Questions
Can any Logitech dongle be reprogrammed?
No. Logitech documents only pairing supported devices to matching receiver types. There is no documented way to rewrite the dongle's firmware or change its core compatibility.
Can a Unifying keyboard work with a Logi Bolt receiver?
No. Logitech states that Unifying products cannot be paired to a Logi Bolt receiver, and Logi Bolt products cannot be paired to a Unifying receiver.
Can a Logi Bolt mouse work with a Unifying receiver?
No. These two receiver families are not cross-compatible. You must use the correct receiver type for your device.
Is there an official iPhone or Android method to pair a Logitech dongle?
No relevant iPhone or Android reprogramming or pairing path is documented in Logitech's current support pages. The pairing process requires a computer running Logitech Unifying Software or Logi Options+.
What is a Bluetooth dongle?
A Bluetooth dongle is a small USB adapter that adds Bluetooth connectivity to a computer, allowing it to connect to Bluetooth devices like keyboards, mice, and headphones. This is different from a Logitech Unifying or Logi Bolt receiver, which uses proprietary wireless technology and cannot be used with standard Bluetooth devices.
