Trying something new here. This Asus board has similar documentation as my Asus Prime 370 did in that the port numbers are usually addressed on the board. I'm not saying this is right, I'm saying its probable. Check it out below.
For example the four USB 2.0 Ports on the rear I/O are named
USB_E5678. That would tell me
HS05, HS06, HS07 , HS08.
Now below it are the two USB 3.0 Ports by the LAN are named
LAN2_U32G1_E34. LAN2 would be the lan portion. U32G1_E would be the port type (3.0). Then we see 34. So, my guess would be that this set of ports is
HS03, HS04, SS03, SS04.
Then we see
LAN1_U32G1_E12...safe to assume this is
HS01, HS02, SS01, SS02.
Now we take a look at the 2.0 Headers labeled
USB56 and USB78. But we've already used 5, 6, 7, 8 on the rear I/O. My guess is they are sharing controllers.
Next up is the 3.0 Header
U32G1_910. Applying the same logic, that would be
HS09, HS10, SS09, SS10.
Lets exclude the Type C port for now.
HS01 - 2.0 Blue by Lan 1 (bottom ethernet port)
HS02 - 2.0 Blue by Lan 1 (bottom ethernet port)
HS03 - 2.0 Blue by Lan 2 (upper ethernet port)
HS04 - 2.0 Blue by Lan 2 (upper ethernet port)
HS05 - 2.0 Black on Rear I/O
HS06 - 2.0 Black on Rear I/O
HS07 - 2.0 Black on Rear I/O
HS08 - 2.0 Black on Rear I/O
HS09 - 2.0 for internal 3.0 Header
HS10 - 2.0 for internal 3.0 Header
SS01 - 3.0 Blue by Lan 1 (bottom ethernet port)
SS02 - 3.0 Blue by Lan 1 (bottom ethernet port)
SS03 - 3.0 Blue by Lan 2 (upper ethernet port)
SS04 - 3.0 Blue by Lan 2 (upper ethernet port)
SS09 - 3.0 for internal 3.0 Header
SS10 - 3.0 for internal 3.0 Header
The problem is we shouldn't go over the 15 port limit. However, OpenCore has a quirk that we can temporarily use labeled XhciPortLimit.
This could all be wrong but lets give it test shall we? Here's what we need to do:
- Disabled USBInjectAll.kext and SSDT-UIAC (if you have them)
- Disabled your current USBPorts.kext
- Add my USBPorts.kext to your EFI and Config (attached below)
Enabled XhciPortLimit Quirk
- Clear NVRAM
If it fails to boot its most likely that Quirks fault.
