Add kernel driver modules for steering wheels (hid-tmff2 in particular)

Open napaalm opened this issue 4 months ago • 5 comments

Describe the package

First of all, thank you for including a simple one-click method to install oversteer! Unfortunately though that's not sufficient to use my steering wheel (a Thrustmaster T300RS) because it requires a custom kernel module, which is hid-tmff2.

It's a particularly painful issue because, from what I understand, DKMS packages are not supported by rpm-ostree, and because of ublue-os/bazzite#899 I can't build the module locally either (instead I have to build it in a toolbox where I installed the right kernel headers).

I would propose to include in bazzite all the custom drivers required by oversteer, which are (from the project's README):

Finally, I want to point out that, even when I managed to load the custom module, my wheel wouldn't work on proton games on Steam, so I found hid-tmff2#54 and after adding the following udev rule on it started working properly:

KERNEL=="hidraw*", ATTRS{idVendor}=="044f", ATTRS{idProduct}=="b66e", MODE="0660", TAG+="uaccess"

I'll let you figure out which udev rules should be added to bazzite by default, considering that a /usr/lib/udev/rules.d/99-thrustmaster-wheel-perms.rules already exists (and I assume it comes from oversteer) but only changes the permissions to configure the device and not to access it.

transffered issue to the kmods repo for easier tracking

whoops! I'll just leave it back in bazzite for now

How did you load the module? I am trying to add hid-fanatecff but FS is read only. I've tried: steamos-readonly enable - not found sudo btrfs property set / ro false - doesn't work mount -o remount,rw / - doesn't work

Thank you in advance.

How did you load the module? I am trying to add hid-fanatecff but FS is read only.

@mmhorda you shouldn't try to modify the root filesystem directly, as it is immutable by design (see https://docs.fedoraproject.org/en-US/fedora-silverblue/technical-information/).

You could technically build the module and layer it to your installation, but you would have to create a new layer after every kernel update because DKMS is not supported yet.

My current solution is to rebuild the module and load it every time I log in:

  • Clone the repository in your home, git clone https://github.com/gotzl/hid-fanatecff.git ~/hid-fanatecff
  • Write the script ~/wheel-driver.sh with the following content:
#!/bin/sh
set -x
make -C ~/hid-fanatecff clean
make -C ~/hid-fanatecff
sudo insmod ~/hid-fanatecff/hid-fanatec.ko
sudo cp ~/hid-fanatecff/fanatec.rules /etc/udev/rules.d/99-fanatec.rules
sudo udevadm control --reload-rules && sudo udevadm trigger
  • Run the script every time after you reboot the system, either manually or with some other mechanism.

I just pasted my script for hid-tmff2 and adapted to hid-fanatecff, so you might need to fix it, but you get the idea. Also, you might need to rpm-ostree install some tools needed for compilation.

Let's hope these modules get added soon so we won't need to use this workaround.

I made it work but then i gave up :)

Basically I placed compiled module to /usrl/local/lib/kernel/ (created folders if missing then created /etc/rc.local file and added
insmod /usrl/local/lib/kernel/hid-fanatecff.ko - so it would be loading on the boot it worked (wheel, pedals, shifters, shiter, etc) but then. no FFB in ACC - No idea how to debug from here. then issue with external GPU + Monitor over thunderbol - didnt work (wored in desktop mode with super huge lag and 75Hz on monitor) so I gave up,

Otherwise it is a very cool idea (works on windows) have a handhld and hook it up to a sim rig with eGPU for a drive.
