Razer Synapse Not Detecting Razer Devices in Windows 10/11

It is the official software for customizing Razer devices such as keyboards and mice. However, Synapse does not always detect linked Razer devices. As a result, users cannot configure their devices because they do not appear in the Synapse software.

The issue of Synapse not detecting devices has primarily been reported with Razer mouse, Razer headset and Razer keyboard. That issue, however, can also occur with Razer headphones, broadcast microphones, and other attachments that software will generally detect. This is how you can fix the Synapse software in Windows 10 and 11, not detecting Razer devices.

Before you begin debugging, remember that Synapse will not detect non-Razer devices. Some Razer items are even incompatible with Synapse 3.0 and 2.0. Also, Synapse isn’t detecting your hardware since it isn’t supported. So check that your Razer Synapse software supports the device it isn’t seeing.

Supported hardware may be found on the Razer Synapse 3 sponsored device page. On that screen, click a category to see if your device is listed. The Razer Synapse 2.0-supported device page can also confirm compatibility with version 2.0. Your Synapse software should detect your device if it is listed as supported hardware on one of those pages.

1. Run the Hardware and Devices Troubleshooter

The Hardware and Devices troubleshooter in Windows can identify and even resolve issues with the Razer device that Synapse isn’t detecting. That troubleshooter, however, is not displayed in Settings. Nonetheless, you can use Command Prompt to run the Hardware and Devices troubleshooter as follows:

 

1. Ascertain that your Razer device is linked to your PC.
2. On your Windows 11/10 taskbar, click a Type here to search (magnifying glass) button or box.
3. In the Type here to search box, type cmd to find Command Prompt.
4. In the Windows search tool, type Command Prompt.
5. Run the following Hardware and Devices troubleshooter command:

msdt.exe -id DeviceDiagnostic

6. In the Hardware and Devices troubleshooter, click Next.

7. Select Use this fix for any resolutions suggested by the troubleshooter.

2. Plug the Razer Device into an Alternative USB Port

This problem can occur due to USB port connectivity difficulties. Some users reported that plugging Razer devices into other USB ports on their PCs fixed the issue of Synapse not detecting them. So, try unplugging your Razer device and inserting it into a different USB port. Also, plug the machine directly into your PC without using any USB hubs.

Before plugging your device into another port, selecting the Remove Device option in Settings is also a good idea. To do so, press the Windows logo + I key, select Bluetooth and devices, and click View more devices. Then, click the three-dot button for your Razer hardware and select Remove device. Next, choose a Razer peripheral in the Bluetooth & other devices tab of Windows 10’s Settings app and press Remove device.

3. Select Synapse’s Repair Option

Many users have also reported that by selecting the Repair option for that software, they could fix Synapse not detecting devices. For example, you can choose the Repair option for Synapse on a Razer Gaming Software window. In Windows 11/10, you can select that option as follows:

9. Reboot the Windows PC to allow the device drivers to be reinstalled automatically. In Device Manager, you can also select Action and Scan for hardware changes to uninstall and reinstall peripherals.

6. Disable Antivirus Use

Temporarily disable antivirus software on your PC to confirm that it is not interfering with Synapse. For example, you can disable Windows Security’s real-time protection by following the steps outlined in our guide to disabling Microsoft Defender. If you have a third-party antivirus program established on your computer, disable its shield using the context menu of its system tray icon.

After disabling antivirus software on your PC, launch Razer Synapse to see if it identifies your devices. If this possible resolution succeeds, add Razer Synapse to the exclusion list in Windows Security or other security software. Then turn back on your antivirus protection.
