README.rst

This allows to use gyroscope, buttons and axes of DualShock 4 with Cemu over network or locally on any supported Linux distribution.

Implementation is quite dirty, not configurable and have only been tested with The Legend of Zelda: Breath of the Wild.

• Use dbus instead of deprecated hcitool for raw mode
• Update to create both a XInput to be used for controller with Rumble and DSU for Motion without needing to be started before cemu

The ds4drv driver is written in Python

# Install (or update to) the latest version of ds4drv-cemuhook from GitHub pip3 install -U https://github.com/Dashboy1998/ds4drv-cemuhook/archive/master.zip

The driver must be started after cemu for rumble support

The driver supports all versions of Sony DualShock 4 controllers (I use DS4v2) connected via USB or Bluetooth.

My version of ds4drv has 5 additional command line arguments (all are optional):

• —udp — starts UDP server. Without this flag ds4drv acts just like the official version;
• —udp-host — tells UDP server to what interface it should bind (default: 127.0.0.1);
• —udp-port — UDP port on which server will be listening (default: 26760);
• —udp-no-touch — do not send touchpad touches to UDP clients;
• —udp-remap-buttons — an option for those, who doesn’t like Nintendo’s button layout. It just swaps A ↔ B and X ↔ Y buttons only for UDP clients.

Connecting controller and starting the driver

Connect the controller & setup using the XInput API

then start the driver using this command:

python3 -m ds4drv --hidraw --udp

If you see a Permission denied error, you may need to copy this file to /etc/udev/rules.d/ and then execute this command: sudo udevadm control —reload . This udev rule allows to access the controller from user space without root privileges. After that reconnect your controller and try again.

You should see something like this if controller has been connected successfully:

[info][controller 1] Connected to Bluetooth Controller (AA:BB:CC:DD:FF:EE hidraw4) [info][controller 1] Battery: Fully charged

This part is very easy. Cemuhook connects to localhost:26760 by default, so you just need to choose the first controller (DSU1) in Options — GamePad motion source .

• Python 2.7 or 3.3+ (for Debian/Ubuntu you need to install the python2.7-dev or python3.3-dev package)
• python-setuptools
• hcitool (usually available in the bluez-utils or equivalent package)

These packages will normally be installed automatically by the setup script, but you may want to use your distro’s packages if available:

ds4drv has two different modes to find DS4 devices, decide which one to use depending on your use case.

Supported protocols: Bluetooth

Unless your system is using BlueZ 5.14 (which was released recently) or higher it is not possible to pair with the DS4. Therefore this workaround exists, which connects directly to the DS4 when it has been started in pairing mode (by holding Share + the PS button until the LED starts blinking rapidly).

This is the default mode when running without any options:

Supported protocols: Bluetooth and USB

This mode uses the Linux kernel feature hidraw to talk to already existing devices on the system.

To use the DS4 via bluetooth in this mode you must pair it first. This requires BlueZ 5.14+ as there was a bug preventing pairing in earlier verions. How you actually pair the DS4 with your computer depends on how your system is setup, suggested googling: bluetooth pairing

To use the DS4 via USB in this mode, simply connect your DS4 to your computer via a micro USB cable.

If you want to use ds4drv as a normal user, you need to make sure ds4drv has permissions to use certain features on your system.

ds4drv uses the kernel module uinput to create input devices in user land and the module hidraw to communicate with DualShock 4 controllers (when using —hidraw ), but this usually requires root permissions. You can change the permissions by copying the udev rules file to /etc/udev/rules.d/ .

You may have to reload your udev rules after this with:

$ sudo udevadm control --reload-rules $ sudo udevadm trigger

The preferred way of configuring ds4drv is via a config file. Take a look at ds4drv.conf for example usage.

ds4drv will look for the config file in the following paths:

. or you can specify your own location with —config .

You can also configure using command line options, this will set the LED to a bright red:

See ds4drv —help for a list of all the options.

ds4drv does in theory support multiple controllers (I only have one controller myself, so this is untested). You can give each controller different options like this:

$ ds4drv --led ff0000 --next-controller --led 00ff00

This will set the LED color to red on the first controller connected and green on the second.

• Bluetooth 2.0 dongles are known to have issues, 2.1+ is recommended.
• The controller will never be shut off, you need to do this manually by holding the PS button until the controller shuts off
• Needs to be started after cemu for Rumble
• Does not work in raw mode as it relies on deprecated hcitool.

Check here for frequently encountered issues.

Failed to create input device: «/dev/uinput» cannot be opened for writing

This could be because the uinput kernel module is not running on your computer. Doing lsmod | grep uinput should show if the module is loaded. If it is blank, run sudo modprobe uinput to load it. (The uinput module needs to be installed first. Please check with your distro’s package manager.)

To have the uinput module load on startup, you can add a file to /etc/modules-load.d . For example:

# in file /etc/modules-load.d/uinput.conf # Load uinput module at boot uinput

The DualShock 4 report format is not open and had to be reverse engineered. These resources have been very helpful when creating ds4drv:

README.md

By Andrew Myers, Tom Paoloni, and Quinlan Deval

This project allows you to map a Sony DualShock 4 (Playstation 4) controller to keyboard input over USB. This can be used to play games, or even perform normal computer tasks with a controller rather than the standard keyboard. By configuring the layout of keys, you can specify how to make the controller fit your needs best.

This project was done for CSE2431 at The Ohio State University. It’s functionality is not complete nor guaranteed.

In order to use this project, you must install libxdo-dev. Xdo is a tool used for simulating keyboard input and is used for generating output from controller button presses. It can be installed using the following command:

To make the project, run make and then to load the module and run the driver, run make init , both from the project’s root folder. Be sure that the controller is plugged in and that you are a super user before running make init .

Finally, run sh make_node.sh as super user. This makes a device node that can be listened to for controller input.

To exit and unload the driver, run make exit as super user

To specify how the layout should be setup, go to the key_map.config file. Here, just type in the desired keyboard input for the appropriate DS4 buttons. Save the file, and restart the program if necessary.
