Identify Logi Bolt, Unifying, and fixed Logitech receivers
Use the receiver and device logos to choose the right connection family before attempting to pair a Logitech keyboard or mouse.
Direct answer
The shortest reliable path.
Match the logo on the bottom of the Logitech device to the receiver family. Logitech states that Logi Bolt products cannot pair with other Logitech USB receiver types and vice versa. A device with the Bolt logo can use a Logi Bolt receiver, while a device without a matching multi-device logo may use a receiver fixed to that product.

- 04Operating system
Scope before steps.
Logitech keyboards and mice being connected through Logi Bolt, Logitech Unifying, a product-specific 2.4 GHz receiver, or direct Bluetooth.
Logitech gaming receivers, headset-specific Zone receivers, firmware recovery, or a guarantee that every operating system supports every optional feature.
Procedure
Do this in order.
- 01
Identify the receiver family
Compare the receiver mark with Logitech’s Bolt, Unifying, and product-specific 2.4 GHz examples.
- 02
Match the device logo
Look for the same Bolt or Unifying logo on the keyboard or mouse. Do not attempt cross-family pairing when the marks differ.
- 03
Choose direct Bluetooth when supported
If the device supports Bluetooth, pair it through the operating system without the USB receiver and keep that path distinct in troubleshooting.
- 04
Pair only after compatibility is proven
Use Logitech’s supported pairing software for the matching family and verify input before adding a second device.
Diagnostic matrix
Read the result, not the guess.
| What you see | Check next | What it means |
|---|---|---|
| The receiver is detected but the device never appears | Recheck the two logos and exact model before resetting or reinstalling software. | The host can see USB hardware, but the device and receiver may belong to different families. |
| Bluetooth works but the receiver does not | Treat Bluetooth success as proof of the device, not proof of receiver compatibility. | The device radio path works; the receiver family or pairing remains unresolved. |
| One receiver already controls several Bolt devices | Use the supported Logitech app to review pairings before removing any working device. | Bolt supports multiple compatible devices on one receiver, so preserve the known-good map. |
Stop conditions
Know when not to keep changing things.
- Do not buy a visually similar receiver until its family logo matches the device.
- Do not claim Bolt and Unifying are backward compatible; Logitech states they are not cross-pairable.
- Stop repeated pairing attempts if the device never powers on or enters its documented connection mode.
