I've got a Logitech G700s mouse. Using the extra buttons under Eon worked just fine. Now I've updated to Focal and suddenly all the extra buttons aren't working. Button 1 and 2 and the scroll wheel are working without issue.

Button 1 and 2 + the wheel showed up under xev, but all the other extra buttons did not generate any output. I also ran sudo evtest /dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse and got the same results as with xev. Button 1, 2 and mousewheel are working fine. Everything else doesn't show up.
How do I get the extra buttons to work again?
