Hey.
Firstly thank you for the work you did here, doing Thrustmasters work yourself. Ive recently switched completely to Linux and was pleasantly suprised that even my T300RS could be working.
However Im strugling a bit.
The wheel is working, however the FFB seems to be "dull" and I cant change anything using Oversteer. I think I might have screwed up when building the kernel module, I tried the manual method since the DKMS didnt work. Later I learned that distribution that I use, Fedora, needs to install DKMS manually as well.
So now I built the module twice using both methods and Im not sure if that could be causing any issues. However I have no idea how to clear all of the previous stuff I did.
Wheels is correctly recognized and I can bind all the buttons and pedals in Assetto Corsa just fine. Its only FFB thats "dead", and reading here makes me think that shouldnt be the case for T300.
Running the fftest command returns this:

Hello, it seems like the driver isn't being loaded or is running into some issue that stops it from working, an outdated firmware version comes to mind.

Could you post the output of sudo dmesg -w when you plug in the wheel? I probably only need the last 10 or lines or so, should have some messages with tmff in them.

Hmm, Ill be honest I havent used my wheel in a long time, but I think last time I updated the firmware was last year. Here the output:

Looks like the module isn't being loaded, presumably due to Loading of module with unavailable key is rejected. This is related to module signing, something I thought DKMS handles automagically for the user. I guess I'll need to review how DKMS works, I'll get back to you on that.

There are some quicker ways around the issue, including signing by hand, but it's a bit cumbersome: https://www.redhat.com/sysadmin/secure-boot-systemtap

Another option is to disable SecureBoot, this generally allows unsigned modules to be loaded, but maybe makes your system less secure.

So this will happen regardless if I install the module manually or with DKMS?
Signing by hand, yeah Ill have to pass, my head hurts whenever I see certs :D
Ill try to disable SecureBoot and will report back

/Edit:
Alright, with secureboot disabled, FFB is working! Thank you very much. Now however Oversteer reports I dont have permissions to change any settings. But I guess that might be since Im using the flatpak version...

Oh, I might've misunderstood your initial message. I thought you had already installed via DKMS and that the driver wasn't working, but I think you meant that the install script itself didn't work?

DKMS should handle everything automatically and would at least theoretically be preferable to a manual installation.
The manual installation is also a bit clumsy because you'll have to reinstall the driver anytime your kernel gets updated, DKMS takes care of that as well.

But I guess that might be since Im using the flatpak version...

Sounds plausible. Oversteer should prompt you the first time you run it to install some udev files that give it permission to access the wheel, sounds like something flatpak apps tend to have issues with due to the sandboxing that they try to implement. Try installing from source and see what happens.

Right, just had a look at the DKMS README and they have a section specifically on SecureBoot: https://github.com/dell/dkms?tab=readme-ov-file#secure-boot

TL;DR: DKMS does automatically sign modules, but the user apparently has to tell SecureBoot that DKMS's signature can be trusted.

I guess I must've glossed over that part last time I looked at DKMS, should probably add a note about it somewhere.

Doing some winter cleaning, I believe this can be closed since we got the FFB working and I learned something new about DKMS. :)
