I've had this problem off and on for the past several years, and usually got it fixed within a matter of minutes. Synapse on my task bar can detect that my headset is plugged in but when opening Synapse it doesn't show my headset there, doesn't allow me to change the eq or other settings. I've completely uninstalled synapse and deleted every razer folder possible and reinstalled a clean version, I've installed older versions of Synapse 2, I've plugged the headset into different USB ports with no luck. I've plugged my headset into another computer and it works fine with no problems. I've searched all over and can't find even a temporary fix. I know the headset is supported because it worked fine until 2 days ago. If anyone has some fairly unknown solution or possible fixes it would be greatly appreciated.
