Now i found an entry called "Device Simulation Framework 1.0" in uninstall program windows in control panel. And i uninstalled it .Now the unknown device disappears. I don't know if it's a dependency of other programs. I hope no~ _(:з」∠)_

But the weird part is that I can't delete it. After deleting,it will show up again if I refresh device manager. If it's a virtual device. Why can't I delete it ?
