I agree.
It's a warning with a call trace though. Probably tens of thousands for a 30 min game play, etc. It's an issue with the SDL backend, so it can be mitigated with using the hidraw backend (since this is a HID PID device). It is more of a problem on Proton, where the SDL backend cannot be disabled. It's been brought to my attention by another Simucube 2 user, who uses the device in SteamPlay (Proton). Since I suggested the SDL_HAPTIC_INFINITY commit back then, thought to improve it to mitigate the issue, until the hid-pidff driver (and/or SDL) gets fixed.
BTW, few weeks ago I submitted a PR to Proton's Wine repository, which enables the hidraw backend for Simucube steering wheels and Fanatec pedals. It would fix this issue as well. If you have some time, you can look at it.
