Verify that device is compatible with Synapse 3. Supported device list here.

Update Windows 7 to its latest patch. We will not be addressing this issue for older patches of Win 7 as that may lead to stability/security issues.

Clean installation of Synapse 3 (remove all razer software from pc -> restart -> install synapse 3 -> restart). Windows 7 sometimes will not load drivers until the next session, so a restart is VERY important. Many users can see their devices after a simple restart post-install.

Unverified FIX : If you STILL can't see your device in Synapse 3, we have a potential hotfix in the works, but we have no way to verify its efficacy. If you would like to test this unreleased hotfix, please send me a PM with your exact device (device manager screenshot would be nice), so that I can share the hotfix for your specific device with you.

Hi All,In the recent Synapse patch. We updated all drivers to the newest signatures and it seems to have caused troubles on some Windows 7 PCs specifically so that the devices will no longer show up in Synapse.On our internal QA machines with latest Windows 7 patch installed, this issue is absolutely non-existent. Please help us help you in resolving this issue by following these steps :Cheers!
