Enabling USB on RPI CM4

[bddvlpr]

When attempting to enable USB's on my PI CM4 I thought enabling xhci (through hardware.raspberry-pi."4".xhci.enable = true;) would fix it, but it in turn causes the following build error. Am I missing something or is this just not supported yet?

I've also tried using dwc2 in every mode possible but none of them seem to make my ports work again.
