Dualshock controllers on 4.4 with 3B+

rsn8887

Just a note that this problem seems to also happen when using the Sony DS4 Bluetooth dongles. I am using two of those dongles to pair my two DS4 controllers. In previous versions of RetroPie, Emulationstation only detected 2 controllers, as expected. Now, in RetroPie 4.4, it says 4 controllers detected.

It would be nice if Emulationstation could tell me the names of all the controllers it detected, instead of just a cryptic total number.

I have some additional issues with the controller mapping procedure:

I cannot seem to cancel if I press the wrong button. How do I cancel out of the controller mapping screen without a keyboard?
What am I supposed to press to select 'OK' at the end? I always manically press different buttons, and then, twenty seconds later, the screen goes away by itself. Is there just a really long delay at the end of this mapping screen?
A, B, X, Y are meaningless, there should be an icon showing which button is the one on the bottom, top, left and right. E.g. A is the button on the right (circle), B on the bottom (cross), X on the top (triangle) and Y on the left (square). Currently this information is not displayed at all.

@rsn8887 When you finish selecting all buttons and the "OK" button is selected, you can move up and re-enter any buttons you mis-assigned. I think that if you also press "A" or "B" (can't remember) after they've been set, you may then move up and down to re-assign specific buttons.

Yes, there is a bit of a delay after pressing OK. It's configuring all the supported emulators, etc.

I have to revise my earlier statement regarding the official Sony DS4 USB dongles I am using. After updating from binaries and rebooting, it behaves correctly now. Only two controllers are detected not 4. I am not sure if it was the update or just the reboot that fixed it.

EDIT: See my answer below. It is not fixed. I just forgot I unplugged my second controller dongle.

@rsn8887 Did you update also the kernel and the OS packages ?

rsn8887

I don’t know. I selected the update option in the Retropie setup menu, then it asked me if I want to update from binary or source. I selected binary. I am not sure if that did a kernel or OS update?

Is there a special, separate, option to update kernel and OS

When you choose to - globally - update, there's a prompt if you Want to upgrade the underlying OS packages and the kernel. But that doesn't happen when you upgrade just one package - or the RetroPie script itself.

rsn8887

@mitu I am pretty sure I selected yes there but I don’t remember that question coming up. I did not just update one single package that is for sure.

What do you mean by -globally update? I selected some option like “update all packages” I didn’t see a global update option in the Retropie setup menu.

mitu

@rsn8887 When I say global update, I'm referring to the Update option in the global script menu.

Global update

When you select it, the RetroPie setup script is updated first, some post-update hooks are executed, then - before the packages are updated - there is a prompt to update the OS

OS Update

Regardless of your choice in this setup, all installed packages are subsequently updated (from binary).

rsn8887

Yes I chose that option, I must have pressed yes to the kernel question, but don't remember doing it.

rsn8887

Nevermind I had accidentally removed the second dongle.

So it is still completely broken both using internal Bluetooth, external BT dongle or official Sony DS4 dongle. The problem is that a single DS4 controller shows up as two controllers, and one of those detected controllers reacts only to motion controls, e.g. tilting the controller.

And yes it is still broken both for the Sony DS4 dongle, as well as when using the regular Bluetooth pairing.

Even worse: some emulators such as AdvanceMAME react to BOTH joy1 (tilt/motion controls) and joy2 (regular buttons etc) when trying to map controls inside the emulator, and there’s no way to turn that off that I know off.

any fix on this?

rsn8887

I wonder if a rule along the lines of the ones here
https://github.com/denilsonsa/udev-joystick-blacklist

could be used to disable the erroneous additional controllers that are linked to motion controls?

Maybe adding a file named /etc/udev/rules.d/51-these-are-not-joysticks-rm.ruleswith the content

SUBSYSTEM=="input", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="0268", NAME=="Sony PLAYSTATION(R)3 Controller Motion Sensors", ENV{ID_INPUT_JOYSTICK}=="?*", ENV{ID_INPUT_JOYSTICK}=""

SUBSYSTEM=="input", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="0268", NAME=="Sony PLAYSTATION(R)3 Controller Motion Sensors", KERNEL=="js[0-9]*", RUN+="/bin/rm %E{DEVNAME}", ENV{ID_INPUT_JOYSTICK}=""

Would help for DS3, and maybe adding two similar lines for DS4, with the correct names and ids might fix this problem. I don't know the names and ids for DS4 at the moment.

mitu

@rsn8887 I don't think they're not erroneus, the choice was deliberate to make them like this. The onus lies in the input processing libraries - like SDL - to make use of them.

rsn8887

Maybe in some distant future SDL and all the emulators will find some approach for correct use of the motion controls. But for now, I think the best approach is just to disable them altogether. The nice thing about these rules is that they can be commented out very easily.

mitu

@rsn8887 I agree, it's a quick fix that's easy to implement (maybe toggled on/off).

rsn8887

EDIT: The instructions below don't work. See the latest post in this thread for the correct instructions.

I did some reading and I think the fix involves creating a new file, named
/etc/udev/rules.d/81-disable-DS3-and-DS4-motion-controls.rules

with content

#disable DS3 motion controls
SUBSYSTEM=="input", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="0268", NAME=="Sony PLAYSTATION(R)3 Controller Motion Sensors", ENV{ID_INPUT_JOYSTICK}=="?*", ENV{ID_INPUT_JOYSTICK}=""

SUBSYSTEM=="input", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="0268", NAME=="Sony PLAYSTATION(R)3 Controller Motion Sensors", KERNEL=="js[0-9]*", RUN+="/bin/rm %E{DEVNAME}", ENV{ID_INPUT_JOYSTICK}=""

#disable DS4 motion controls
SUBSYSTEM=="input", ATTRS{idVendor}=="XXXX", ATTRS{idProduct}=="YYYY", NAME=="ZZZZ", ENV{ID_INPUT_JOYSTICK}=="?*", ENV{ID_INPUT_JOYSTICK}=""

SUBSYSTEM=="input", ATTRS{idVendor}=="XXXX", ATTRS{idProduct}=="YYYY", NAME=="ZZZZ", KERNEL=="js[0-9]*", RUN+="/bin/rm %E{DEVNAME}", ENV{ID_INPUT_JOYSTICK}=""

Where XXXX, YYYY, and ZZZZ are the as-of-yet-unknown strings idVendor, idProduct, and name of the motion control device linked to a DS4 Controller. These variables could be determined if someone with a DS4 connected could run cat /proc/bus/input/devices and post the output here. More lines might be neccessary if the DS4 Controller strings change depending on whether it is connected via BT, USB cable or Sony dongle.

The idVendor and idProduct parts might even be removed, and we might only match the name.

I suppose the file should have root permissions (?).

I have a hunch this might work but haven't tested it.

Perfect thanks, so my solution would be this, completely untested so far:

ssh into your RetroPie
enter

sudo nano /etc/udev/rules.d/51-disable-DS3-and-DS4-motion-controls.rules

paste the following the editor

#disable DS3 motion controls
SUBSYSTEM=="input", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="0268", NAME=="Sony PLAYSTATION(R)3 Controller Motion Sensors", ENV{ID_INPUT_JOYSTICK}=="?*", ENV{ID_INPUT_JOYSTICK}=""

SUBSYSTEM=="input", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="0268", NAME=="Sony PLAYSTATION(R)3 Controller Motion Sensors", KERNEL=="js[0-9]*", RUN+="/bin/rm %E{DEVNAME}", ENV{ID_INPUT_JOYSTICK}=""

#disable DS4 motion controls
SUBSYSTEM=="input", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="09cc", NAME=="Wireless Controller Motion Sensors", ENV{ID_INPUT_JOYSTICK}=="?*", ENV{ID_INPUT_JOYSTICK}=""

SUBSYSTEM=="input", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="09cc", NAME=="Wireless Controller Motion Sensors", KERNEL=="js[0-9]*", RUN+="/bin/rm %E{DEVNAME}", ENV{ID_INPUT_JOYSTICK}=""

Hit CTRL-x and y to save
reboot and see if motion controls are disabled

It probably requires some tweaking still, but something along these lines should work.

I am confused that the Name is "Wireless Controller" and not Dualshock 4 or some such. Maybe a bug in the Linux Kernel?
