Support for CSL Elite Pedals V2

[pmarkee]

Hi, first of all thank you for the existence of this project!

My question is basically the title, I take it the CSL Elite V2 pedals are not yet supported? It is seen by Oversteer, however it does not detect analog input, the pedals sit at 0% and jump to 50% when almost fully pressed in.

Hi,
in principle, you don't need an extra driver for the pedals. Their functionality is covered by the generic HID driver in the kernel.
What could explain your issue would be that the ranges and/or deadzones are miss-configured. Could you check what evtest is seeing? And the output of evdev-joystick -s /dev/input/by-id/usb-Fanatec_*-event-joystick?
Does evdev-joystick --evdev /dev/input/by-id/usb-Fanatec_*-event-joystick --deadzone 0 --fuzz 0 --flatness 0 maybe help?

Edit: Also, are these pedals connected to the wheel base or connected directly to the PC via USB? If it's USB, what is the ProductID? I then could add the PID to the driver, which might also help in some games with their detection, and also the evdev-joystick command is then executed via udev-rule.

It seems to be possibly an issue with Oversteer, evtest shows analog inputs as expected and it also shows up correctly in-game. I plugged it into the wheelbase, but it also works via USB. ProductID is 0eb7:6206. Thanks for the help!

One more thing if you don't mind, is it possible to set the force of the brake pedal, like in the official Fanatec software under Windows?

[gotzl]

Ok, good to hear that it works! In case you connect it via USB, it might work similarly to the V1. For a quick test you could change

hid-fanatecff/hid-ftec.h

Line 17 in dcb93dc

#define CSL_ELITE_PEDALS_DEVICE_ID 0x6204

to your PID, rebuild and reload the module. Then, you should get a sysfs file called load which allows you to set the force... The initial value i s '4', there is no GUI yet ...

If you connect it to the wheel, then currently, the only way to adjust the force is via the tuning-menu directly on the wheel.

Yes, you can change settings directly in the menu on your wheelrim.

I don't know if gotzl fixed permission issues writing directly to sysfs files tho.

Rebuilt and installed the driver, the value in the load file is 0 right now. But also the pedals are not showing up under evtest anymore (earlier they did even without the wheel) so I'll probably just stick to configuring it on the wheel rim.

Btw @gotzl do you accept donations? You really deserve a nice cold beer for all this work! And all other contributors too of course.

Forgot to say that reading back the value doesn't work currently ;)

That's unexpected ^^ Hmm.. If you have the time, could you retest? Maybe observe what journalctl -xfk says when you plug-in the pedals...

Thanks, I'll take the beer if you get to Germany :) Not sure about donations, I'll think about it ...

Seems no /dev/input/eventX file for it. Also, I guess this is expected but with the unmodified 0.1.1 version the sysfs for it is under /sys/module/hid_generic/drivers/hid:hid-generic/0003:0EB7:6206.XXXX, with the patched one it's /sys/module/hid_fanatec/drivers/hid:fanatec/0003:0EB7:6206.XXXX.

Edit: not sure if it matters but it's also the same if the wheelbase is also plugged in

[gotzl]

Seems no /dev/input/eventX file for it.

It is 'implicitly' created by the input subsys. You should see it at /dev/input/by-id/usb-FANATEC_*.
The change of the sysfs directory is expected, it shows that your patch really did work and the hid-fanatec driver is loaded for the device.

Edit: not sure if it matters but it's also the same if the wheelbase is also plugged in

If you connect the pedals via USB, they are completely independent from the wheel-base ...

I just found I don't get input from the pedals anymore after rmmod hid-fanatec followed by modprobe hid-fanatec, unless I replug the USB. Maybe this was the case for you as well?

[pmarkee]

Sorry for the late reply, I was away from home for a few days.

I've tried again and it's still not showing up in evtest by default, but via sudo evtest /dev/input/by-id/usb-FANATEC_* it works. Setting brake force through the load file works as well.

I've managed to get this exact behavior. Worth noting that with the patched version, when I re-plug it it doesn't respect the previously set brake force (not referring to readback, but the actual input I see in evtest) so you have to set it again through the load file.

Anyway thanks again for your help!

[gotzl]

Great to hear that it is working! This means I can just add these pedals and treat them similar to the V1. So I'll reopen this ticket to track the work on the 'proper' implementation.

Yes, that's to be expected. The device has no memory. If you want to have a specific load set every time the module loads, you can do what I suggested in this comment .
