How do I manually add UDEV files on Oversteer flatpak on my Steam Deck?

[RaymondYouTube]

Okay, so I downloaded the flatpak version of Oversteer on my Steam Deck. I'm using a PlayStation 2 Logitech Driving Force Pro, but when I open Oversteer, I got a message that said "You don't have the required permissions to change your wheel settings." so I downloaded the UDEV files, but I don't know where to install them.

I'm told that with the flatpak version, you have to manually install them, but how do I do that? On my Steam Deck, the files for the Oversteer flatpak is located at /home/deck/.var/app/io.github.berarma.Oversteer/ so where do I install the UDEV files? If anyone knows please tell me. Thank you.

Install the latest udev rules in /usr/lib/udev/rules.d and reload udev with sudo udevadm control --reload-rules && sudo udevadm trigger.

Thanks @jo5huajohn. Instructions added to the README (47a9af9).

I tried moving the files to that location, but I got an error that I could not write to this location "/usr/lib/udev/rules.d/".

You need admin rights. You can use sudo to copy the files.

And for me to use sudo to copy the files, how do I get admin rights?

sudo is a command that executes another command with admin rights, like sudo copy.

You could also check if your file explorer has an option to open a folder as admin.

Okay, I don't know what I'm doing. I'm trying to figure out how to use 'sudo' to add these files into that location. But because it doesn't tell me how to add these files in that location using 'sudo' I don't know what to do.

All this could be done using desktop tools like the file browser. Using the terminal should be optional.

Anyway, since you seem to prefer the terminal, these commands should work:

sudo wget https://github.com/berarma/oversteer/blob/master/data/udev/99-fanatec-wheel-perms.rules -P /usr/lib/udev/rules.d/
sudo wget https://github.com/berarma/oversteer/blob/master/data/udev/99-logitech-wheel-perms.rules -P /usr/lib/udev/rules.d/
sudo wget https://github.com/berarma/oversteer/blob/master/data/udev/99-thrustmaster-wheel-perms.rules -P /usr/lib/udev/rules.d/

I tried it, and I cannot do write into that location due to the Steam Deck's read-only file system.

Okay, I managed to put the files into that location by disabling the SteamOS read-only file system. I used the terminal to put the files in, reloaded in the rules, and re-enabled the SteamOS read-only file system. But then I ran into another issue where it made these files as HTML files, not text files.

I found a fix. You're supposed to type this into the terminal sudo wget https://raw.githubusercontent.com/berarma/oversteer/refs/heads/master/data/udev/99-fanatec-wheel-perms.rules so that you'll get the text file.

Never mind. It just made those into manual page files instead of text files. And now I got useless crap in this location.

If your filesystem is mounted read-only, you won't be able to install the files. You can try installing to /usr/local/lib/udev/rules.d instead.

If this doesn't work I'd recommend asking for help on SteamOS forums. I don't have any experience with the Steam Deck.

Well, I can't get that to work either because there no udev folder in /usr/local/lib/ And if I try to create a folder, it gets an error message, because that location is also tied to the read-only file system. So I cannot install the files on either of those locations unless I disable the SteamOS read-only file system.

I found a solution on Steam Deck for the PlayStation 2 Logitech Driving Force Pro and other wheels.

Copy the rules files to: /etc/udev/rules.d/

But instead of using wget, you use cp. It should look like this:
sudo cp 99-fanatec-wheel-perms.rules /etc/udev/rules.d/
sudo cp 99-logitech-wheel-perms.rules /etc/udev/rules.d/
sudo cp 99-thrustmaster-wheel-perms.rules /etc/udev/rules.d/

And then reload the udev rules:
sudo udevadm control --reload-rules
sudo udevadm trigger

Restart your Steam Deck just to make sure everything takes effect.

This way, you'll be able to install the permission files without having to disable the Steam Deck's read-only file system.
