Logitech G923 - where to start?

I’m running Endeavour OS with kernel 5.16.16-zen1-1-zen. I just got a logitech g923 (PS4/PC version) (wheel, pedals, shifter - the pedal and shifter connect to the wheel base, and a single USB cable runs to the PC). It seems it’s detected. lsusb shows:

With evtest, I get this:

And it’s similar with jstest. In both cases, pressing buttons registers input, but turning the steering doesn’t show up, and neither do gear shifts, or any pedal actions.

When trying to use Steam, it sees the G923 as a generic controller and not a wheel.

Any ideas on how to get the wheel recognised? Do I need to install some packages?

There’s a third-party driver that might be worth trying (works with G29), https://aur.archlinux.org/packages/new-lg4ff-dkms-git, although it looks like G923 support is still in development:

(Therefore, unless it has a G29 “compatibility mode” then the current “solution” is to use Windows, but that also means you can use Crew Chief so it’s not all bad.)
