• Reinstalling jupiter-hw-support fixes this till next boot.ˢᵒᵘʳᶜᵉ
• Running # jupiter-controller-update fixes this across boots.ˢᵒᵘʳᶜᵉ
• This doesn't seem tied to the firmware version as it happens on a reinstall.ˢᵒᵘʳᶜᵉ

I think we can run jupiter-controller-update in steamos-update script, but not sure how to properly test.
