Reinstating Detection of Razer Devices by Synapse Software

Razer Synapse is the official software for configuring Razer devices, such as keyboards and mice. However, Synapse sometimes doesn’t detect connected Razer devices. Consequently, users can’t configure their devices because they don’t show up in the Synapse software.

The issue of Synapse not detecting devices is mostly reported for Razer mice and keyboards. However, that issue can also occur for Razer headphones, broadcast microphones, and other accessories that software will usually detect. This is how you can fix the Synapse software not detecting Razer devices within Windows 10 and 11.

But First, Double-Check Device Compatibility With Razer Synapse

First, before you hop into the troubleshooting steps, note that Synapse will not detect non-Razer devices. There are even some Razer products Synapse 3.0 and 2.0 don’t support. It might be the case Synapse isn’t detecting your hardware because it doesn’t support it. So, double-check your Razer Synapse software supports the device it’s not detecting.

You can check supported hardware at the Razer Synapse 3 supported device page . Click a category on that page to see if your device is listed there. You can also check compatibility for version 2.0 at the Razer Synapse 2.0 supported device page. If your device is listed among the supported hardware on one of those pages, your Synapse software should detect it.

1. Run the Hardware and Devices Troubleshooter

Windows has a Hardware and Devices troubleshooter that could identify and even resolve issues with the Razer device Synapse isn’t detecting. However, that troubleshooter isn’t visible within Settings. Nevertheless, you can run the Hardware and Devices troubleshooter from Command Prompt like this:

msdt.exe -id DeviceDiagnostic
ClickNext in the Hardware and Devices troubleshooter.
SelectApply this fix for resolutions the troubleshooter suggests.

2. Plug the Razer Device into an Alternative USB Port

This issue can occur because of USB port connection issues. Some users have revealed that plugging Razer devices into different USB ports on their PCs resolved the issue of synapse not detecting them. So, try unplugging your Razer device and plugging it into an alternative USB port. Also, plug the device directly into your PC without using any intermediary USB hubs.

It’s also recommended to select aRemove device option in Settings before plugging your device into another port.

Temporarily antivirus apps on your PC to ensure they aren’t blocking Synapse in any way. You can disable Windows Security’s real-time protection as outlined in our guide for disabling Microsoft Defender . If there’s a third-party antivirus tool on your PC, turn off its shield via its system tray icon’s context menu.

Launch Razer Synapse to see if it detects your devices after disabling antivirus software on your PC. If this potential resolution works, consider adding Razer Synapse to the exclusion list in Windows Security or alternative security software. Then turn your antivirus protection back on.
