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 theRazer 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 theRazer 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.
