USB header on Mac Pro 4,1 / 5,1
I'm installing a Fenvi PCIe Wi-Fi ac card on my Mac Pro 5,1 (flashed 4,1). It's based on the Broadcom BCM94360CD so is natively supported in MacOS X. However, if I want Bluetooth 5.0 (which I do for Airdrop and HandOff) i need to attach a cable from the card to a USB header socket (see diagram, which is for a PC installation). Is there a corresponding USB header anywhere on the Mac Pro motherboard?
TIA,
Tim
