Using the Bluetooth 4.0 LE Dongle, I mainly got it to use for my PlayStation 4 Controller. I connect it and it works, but when Windows said Controller Connected, the light on the PS4 Controller is gone, and shortly after the connection is lost. I try again, and the same result is presented. The Dongle does work, I tried it with my phone on the same distance, and the Controller has been charged.
I use Windows 7 Home Premium, 64-bit.
