Teensy MicroMod PCB isn't detected via USB

I’m building a synth based on the Teensy MicroMod platform. I just received my first prototype boards - yay!

Unfortunately, when I connect the board to my computer via USB-C, it isn’t detected. I tried to replicate the connections on the MicroMod ATP board in my build. a few things I left out from the ATP build:

Pin 9 - USB_VIN (didn’t think the Teensy needed the 5v from USB)
Pin 35 - USBHOST_D+ (Not using USB host)
Pin 37 - USBHOST_D- (Not using USB host)

The Teensy MicroMod schematic makes reference to a “3.3v_CONTROLLED”. It powers the programmer … but I don’t see where that is coming from.

I’m not sure how to post my schematic here.

Update - I wired pin 9 to the 5v USB line and it seems to work now!
