PS3 controller on Windows 8.1 via bluetooth

A PS3 Sixaxis controller can be used as an input device on Windows 8.1.

For this to work the free Motion In Joy (MiJ) application needs to be installed: http://www.motioninjoy.com/download. At the time of writing, for Windows 8.1 x64, select v0.7.1000 (testing).

Using the controller via a wired USB connection almost always works, but using a wireless Bluetooth connection can be a problem.

Possible error: "Wait for bluetooth adabter to be connected" (Yes, there is a typo in adabter)

The causes for this are:

1. MiJ installs its own non-signed bluetooth driver, which is not allowed on Windows 8 unless the system is started with "driver signature enforcement" disabled
2. The bluetooth device's hardware id is not in the INF file of the MiJ bluetooth driver

The following instructions are from WingedT on:

I revised them and put them on my blog in case that post is deleted from the Motion In Joy forum.

Instructions for bluetooth support:

1. Before starting, make sure bluetooth works by clicking the Bluetooth icon in the tray in right-bottom corner and selecting "Show bluetooth devices". If there are none, try "Add a bluetooth device" and try to pair e.g. a mobile phone. If this works, continue
2. Install and start MiJ's DS3 Tool
3. Select "Driver Manager" and click "install all"
   It might be that MiJ drivers for both devices (USB and bluetooth) are installed correctly. In that case they both have a green checkmark at the end in the MotionInJoy column. If one has a red cross, then most probably that is the bluetooth driver and that has not been installed
4. Take the Hardware ID of that device and strip the revision part, i.e. for a Lenovo Y510P this might be that USB\VID_8087&PID_07DA&REV_7869 becomes USB\VID_8087&PID_07DA
5. Open C:\Program Files\MotioninJoy\ds3\drivers\MijXinput.inf in a text editor. 
1. Find and replace:
   ;BLUETOOTH DONGLE
   with
   ;BLUETOOTH DONGLE
   %MIJ.DeviceName%=CC_Install, USB\VID_8087&PID_07DA
2. Delete the following line:
   catalog=MijXinput.cat
3. Save and exit
6. Restart Windows 8 with Advanced Options so Driver Signature Enforcement can be disabled. Open a command prompt (Win + X, command prompt) and type:
   shutdown /r o
7. In the Advanced Options screen, select Advanced Options -> Windows Startup Settings -> Restart
8. In the next screen with the Advanced Option to enable, choose: 7. Disable Driver Signature Enforcement. A reboot will follow
9. Select "Driver Manager" and click "install all". Now both devices should have a green check mark:
   
   
10. Exit and restart DS3 tool and once again click "Load driver". Now the bluetooth driver should be selectable in the BluetoothPair tab:
