This has been making me insane. My Razer Tiamat 7.1 V2 is listed in Devices and Printers as "Unspecified" its a big grey box. I've removed and re-added it from device manager and it still populates there as opposed to as a headset. The naga, and my chroma v2 etc all show up properly, but the headset is no bueno. Anyone seen this and have a fix?
