Controller detected but not working

Hi folks.

I have a Flydigi Vader 4 Pro, the USB dongle is connected to my ROG Ally, which is running Bazzite.

When I connect the controller, the controller shows up in dmesg
The controllers /dev/input/ entry also shows up, I'm even able to cat the endpoint and see data from the controller as I press buttons from the controller
Launching KDEs Game controller settings page, I only see one controller, the Allys builtin.
In steam, the Flydigi does not work.

Any ideas?
