You may have a different version of the 8300 USDT motherboard, however, mine does have a USB header inside. Facing the front, it is located on the right-hand side of the motherboard right next to the HSENSE header, and is noted as the MEDIA reader header, because the 8300 USDT has an optional SD card reader that can connect there. I have installed a miniPCIe wifi-bt combo and attached the requisite USB data lines to that internal header. It is a 8 pin (two port) header.Connected up the PCIe Wifi card (Broadcom BCM94360CD) and it works normally, wasn't able to test BT though. For that you'd need a USB 2.0 port adapter or it won't work. No USB 2.0 headers on this motherboard.
BTW, this USDT is one of my all time favorite machines. I installed a 256GB mSATA to dual boot macOS Mojave and Windows 10, the WiFi+BT combo BCM94360CSAX Airport Bluetooth (needs an adapter card) and ran the HP 8200 USDT Mozart Antenna KIT Assembly New 621903-001 621904-001 - 640247-001 to get the antenna outside the case as designed by HP. I also added a 4TB HHD, partitioned into 2 x 2 TB, because of the BIOS limit of 2 TB. All works a treat.
One thing to note: HP didn't implement the FULL PCIe spec on this motherboard miniPCIe port; specifically there is no pass-through of the USB on pins 36 and 38 (D- and D+, respectively). That's why an adapter is needed so that you can connect the WiFi+BT card to the internal header elsewhere on the board, as mentioned.
I was interested in the MXM, until I understood how poorly it would work even in Windows and unsupported in macOS.
Now I am following your progress with great interest!
