Hi Tanuj,

The button mapping of the kernel driver should be fine (you can
confirm using evtest). SDL2 requires a button/stick mapping and I need
to provide one to them as I'm not sure if they have the one for the
kernel driver. Depending on your SDL2 version, SDL also bundles its
own HID driver, which uses hidraw. Not sure which is getting picked up
here, I guess the kernel driver. I will have quick look at this today
or so if time permits.

Thanks,
Roderick Colenbrander

Hi,

If someone could point me in the right direction is all I ask. eg what
to google / where to look for the answers?

I know this is the wrong place to email for this, but I wasn't able to
find any information of button mapping issues on a Playstation 5
Dualsense controller and how to resolve it. I was able to find the
announcement of the driver and this email address. I really don't want
to be sending this email since I'm fairly sure it is as always an
issue on my own system. However if this is an actual issue I have
included details of my system below.

Essentially, the issue is that the button I press on the controller
doesn't match the key detected on the computer; where connected with
USB or Bluetooth. As far as I can tell this is because the controller
is not using the correct driver somehow. I cant't figure out:

1) How to use the correct driver?
2) Why I need to force the kernel to use the correct driver?

Currently this is the mapping I get:

This remains consistant across reboots and switch between bluetooth
and usb. The trackpad seem to work fine over USB, I haven't yet tested
the Headset, accelerometer, and gyroscope yet.

According to [This
Comment](https://aur.archlinux.org/packages/hid-playstation-dkms/#comment-805935)
on the AUR hid-playstation-dkms page, I should not install this on
kernel higher that 5.12.

The only "solution" I seem to be able to find to this is on the [Arch
Wiki]( https://wiki.archlinux.org/title/Gamepad#Playstation_5_(Dualsense)_controller
) is using a [xbox driver that runs in the user
space](https://gitlab.com/xboxdrv/xboxdrv) to remap the keys which
seemed weird since there is already an apropriate driver already. Also
there is apparantly some thing call
[linuxconsole](https://sourceforge.net/projects/linuxconsole/) but I
wasn't able to remap the keys with that.

Tanuj
