Might be worth going back to v5.10 drivers. Since Windows 10 came out, I cannot get my G25 to work on it at all, without these legacy drivers.
I have a Logitech keyboard and game board, but to work, I have to uninstall all Logitech software first. Install the v5.10 driver to detect the wheel - then the latest V8.xx whatever driver for the keyboard and game board.
A faff and imo - just Logitech being lazy. It wouldn’t take long at all for the devs to adjust the driver file to support the G25 and G27. Both are still very common, actively used wheels.
Oh, and as
@McGherkin says - make sure it’s in a USB2 port. It has a spaz fit randomly when in a USB3 port.
