[Issue] 2520º after connect the wheel base to the pc

[davidm2m]

Hello,
I’m experiencing an issue when using my ClubSport DD+ wheel on Linux with the module. The behavior is as follows:

When the wheel is connected to Linux right after finishing its startup process, it sets the rotation to 25020 degrees, but the actual rotation that gets registered is as if it were 1080 degrees. For example, if you turn the wheel 90 degrees, only about 33 degrees are registered in the games.

If you don’t power off the wheel and then connect it to Windows, it continues to behave the same way: turning the wheel 90 degrees only registers about 33 degrees in the Fanatec software. However, if the wheel is powered off and restarted, it works correctly.

I also noticed that when using Assetto Corsa with Content Manager, this problem is fixed after loading any session with any car, as long as the option “auto match scale to match car direction” is enabled in the wheel configuration.

The SENSITIVITY setting on the wheel is set to AUTO. If I manually set it to 1080 degrees, there are no issues, but then the automatic adjustment per car (handled by the games) is lost.

I’m using Arch Linux with kernel 6.16.1, but this issue has been present for some time. I can’t tell exactly in which version it started happening.

Steps to reproduce:

Power on the wheel and connect it to the PC (I usually leave the USB connected, so it auto-connects right after the startup process).

Check the steering angle. I usually test it in a game other than Assetto Corsa with Content Manager. For example, in AMS2 it’s easy to confirm the issue described above.

To fix the problem, open Assetto Corsa with Content Manager and make sure the option “auto adjust scale to match car direction” is enabled.

If you need any additional information or logs, please let me know (and how to extract them), and I will add them to this issue.

It looks like I’ve found a workaround for the issue. So far, with the initial tests, I haven’t encountered any additional problems.

The solution I’m using is to load the module with the option:

init_range=1080

Here are the checks I performed to verify whether this resolves the problem:

Confirmed that the wheel’s rotation limit is set to 1080 degrees.

Verified that games like ACE, AMS2, etc. correctly detect the rotation angle and that it matches.

Verified that without turning the wheel off, Windows still detects the rotation properly. I also tested changing the rotation to angles higher than 1080 degrees, and everything still works correctly with no issues.

With this configuration, the wheel continues to show “AUTO” for “Sensitivity” in the wheel’s display menu, and Assetto Corsa with Content Manager adjusts the rotation angles correctly just like before.

I think this should be added to the Troubleshooting section so that others encountering the same issue in the future can easily fix it. However, the more appropriate long-term solution might be to check whether this problem is caused by a specific firmware version or update. If so, it may make sense to initialize the wheel at 1080 degrees by default — and if this is only an issue with the CS DD+, then apply the initialization only for that model.
