Compute Module • CM5 carrier board reversible USB 3 not working

Hi everyone,

I am designing a Raspberry Pi CM5 carrier board, with reversible type C connector over USB3. I ran testing with a USB 3 device, and USB3 type C is not reversible. One side shows up as USB3, but shows up as USB2 when the cable is flipped.

Attached schematic below:


I have double checked schematic and layout, and everything seems to be correct. I am running out of idea here, so any help will be greatly appreciated.

Thanks!
