Windows 7: Bluetooth USB adapter - PS4 controller no longer connects wirelessly

24 Jul 2017   #1

Windows 7 Pro 64-bit SP1
Bluetooth USB adapter - PS4 controller no longer connects wirelessly

Hello. I was previously trying to solve a problem where, when plugging in my USB Bluetooth adapter to my computer, Windows would show both the Bluetooth adapter (labelled as CSR8510 A10) and a "Wireless Controller" in my Devices and Printers panel, even though there was no controller connected. Unplugging the USB Bluetooth adapter caused both the Bluetooth adapter and the Wireless Controller to disappear from the Devices and Printers panel.

This was causing problems for me in Steam, which would not recognize my PlayStation 4 controller when I connected it wirelessly using this Bluetooth adapter (the Steam client believed there was already a PS4 controller connected even when there wasn't).

I tried to solve this problem by uninstalling the phantom Wireless Controller driver while the USB Bluetooth adapter was plugged in.

This has made the problem worse. Now when I plug in the USB Bluetooth adapter, only the Bluetooth adapter shows up in the Devices and Printers panel (which is good). But when I then try to turn on my PlayStation 4 controller, the following happens, in order:

1) "A Bluetooth device is trying to connect" message appears in the taskbar
2) I click "Next" in the Add a Device window to allow the connection
3) "Bluetooth HID Device driver driver software installed successfully" message appears in the taskbar, and the Windows USB device connected sound plays
4) A "Wireless controller" appears in the Devices and Printers panel

5) The PlayStation 4 controller immediately disconnects (the light bar that stays on when the controller is connected shuts off)
6) After about 5 seconds, the "Wireless Controller" in the Devices and Printers panel changes to "HID-compliant game controller"
7) The "HID-compliant game controller" disappears from the Devices and Printers panel
8) The Windows USB device disconnected sound plays, and now I'm back where I started

If I try again, the process repeats itself exactly. If I unplug the Bluetooth USB adapter and move it to a different USB port, the result is still the same (on my computer's front panel, I have two USB 2.0 ports and two USB 3.0 ports - all four ports get the same result).

I do not have any problems when connecting the PlayStation 4 controller using a USB cable, only Bluetooth.

I do not know many details about the USB Bluetooth adapter I am using. It is a small (dime-sized) device with a blue light that flashes when it is plugged in, and turns to a steady blue light when a Bluetooth device is connected to it. On one side is printed "SMK Link" in blue lettering, and on the other side there is a Bluetooth logo and the words "V4" and "LE." I've had it for a couple of years now.

I am using Windows 7 Pro x64 SP1. If anyone has any advice for me I would appreciate it.
