Description

new-lg4ff for Linux

upstream

Improved Linux module driver for Logitech driving wheels.

Thanks to Oleg Makarenko for adding support for the Logitech G923 Racing Wheel (PS4/PC version).

Supported devices:

• Logitech WingMan Formula GP (without force feedback)
• Logitech WingMan Formula Force GP
• Logitech Driving Force
• Logitech MOMO Force Feedback Racing Wheel
• Logitech Driving Force Pro
• Logitech G25 Racing Wheel
• Logitech Driving Force GT
• Logitech G27 Racing Wheel
• Logitech G29 Driving Force (switch in PS3 mode)
• Logitech G923 Racing Wheel for PlayStation 4 and PC (046d:c267, 046d:c266)
• Logitech MOMO Racing
• Logitech Speed Force Wireless Wheel for Wii

This module is not compatible with the Logitech G920 Driving Force and XBOX/PC version of the Logitech G923 (046d:c26d, 046d:c26e). Both wheels use the HID++ protocol and are supported by the HID++ driver as of kernel 6.3.

Reports on success or failure using this module on untested devices are welcome.

Differences with the in-tree module

It has all the features in the in-kernel hid-logitech module and adds the following ones:

• Support for most effects defined in the Linux FF API (except inertia) rather than just constant the force effect.
• Asynchronous operations with realtime handling of effects.
• Rate limited FF updates with best possible latency.
• Tunable sprint, damper and friction effects gain.
• It can combine accelerator and clutch.
• Use the wheel leds as a FFBmeter to monitor clipping.
• Added a system gain setting that modulates the gain setting used by applications.
• SYSFS entries for gain, autocenter, spring/damper/friction effect gain and FFBmeter.
