Logitech G920 support

[Edwin]

I submitted the latest version of the Logitech G920 driver. For those feeling brave and wanting to build it, the kernel patch is here:

http://www.spinics.net/lists/linux-input/msg42863.html

Note that you will also need to apply the patch set linked in the description.


Update:

The driver has been accepted for kernel 4.6.

@Edwin thanks for the update on the release of the driver for kernel 4.6.

Thanks for supporting a steering wheel option for GNU/Linux sim racing enthusiasts. As of submitting this post, the G920 seems like a good option when purchasing a steering wheel for GNU/Linux users.

[Edwin]

Even though most games don't require it, the G920 is still the only wheel with complete support of the hardware functions.

Hi, Edwin

Thank you for your hard work! I'm following this doc to make G920 working on ubuntu 16.04,

http://burning-midnight.blogspot.com/2017/11/logitech-g920-steering-wheel-on-linux.html

But the force feedback is still missing. Is there any document how to make it work? Thanks!

[Edwin]

Look in the "Driver package for Logitech Wheels" for instructions on adding the G920 driver to pre-4.6 kernels.

I'm on kernel 4.13. We managed to make the force feedback working by doing the following steps. It's just not turned on by default.

$ ll /dev/input/by-id
usb-Logitech_G920_Driving_Force_Racing_Wheel_for_Xbox_One_0000cc90217ab396-event-joystick -> ../event9
usb-Logitech_G920_Driving_Force_Racing_Wheel_for_Xbox_One_0000cc90217ab396-joystick -> ../js0

It shows that event9 is the thing we are looking for, then run fftest to test it

$ fftest /dev/input/event9
Force feedback test program.

Enter any number to test, and viola!
Thanks!

I quite literally installed Linux (Pop OS) yesterday and I have no idea how to do anything.. could someone tell me in detail what I have to do?
Also I have a G920 and a Thrustmaster TH8A shifter. The kernel I think is 5.0.0-15-generic (typed uname -r to see it I think)

[Edwin]

For the G920 you don't really have to do anything. Should work out of the box. No idea about the shifter though since I don't have one of those. Since that is probably just a HID device, it should work fine as well. You can test it with "evtest" (may not be installed by default).

The g920 is not recognised by ETS2... :( but the th8a works just fine plug and play

I see the problem. You have device 046d:c261, which is the G920 in xbox mode. Upon plugging in the wheel, a package called USB Modeswitch should detect this and switch it over to HID mode, which changes the device to 046d:c262 and is then recognised by the driver. Apparently your USB Modeswitch is not installed (properly) or must have very old data.

ok thanks.. so how do I update or reinstall (I presume) this USB Modeswitch

[Edwin]

Since you have PopOS, you'll have to figure it out for yourself. Ubuntu has it installed and working by default.
