This is the schema of our motherboard.Thank you so much! Deleting the pci key got me past that and into Big Sur. I was booting to a black screen on my 5700XT but realized I mis-spelled "agdpmod=pikera" which was causing the problem. I'm up and going, everything's working! Might map the USB ports differently so that the USB 3.0's on my case work, but otherwise I've got what I need. Thanks again for the guide/EFI folder!
- Internal ports USR01 and USR02 are ignored, as if they did not exist.
- HS is USB2 and SS is USB3.
- HS01 / SS01 is the type C internal port, I do not use it but I don't know if you use it.
- HS11 / HS12 / HS13 are USB2 specific internal ports, note that HS13 is a single port but it has 4 connectors on the back.
- HS03 / SS03 - HS04 / SS04 / HS05 / SS05 - HS06 / SS06 - HS07 / SS07 - HS08 / SS08 are the 6 rear ports that work as USB2 and USB3.
- HS09 / SS09 is the internal port that works as USB2 and USB3.
When I made my USBMap.kext I did it like this so as not to exceed the limit of 15 ports:
- I removed the HS03 and HS04 (USB2) ports from the rear red connectors that with this change only recognize USB3 devices.
- I removed the internal port type C HS01 and SS01.
- all other ports should work fine and at their correct speed.
- how are connected front ports of the case, how many are USB2 and how many are USB3 and in which connectors they are placed.
- if you have an internal Bluetooth device connected to HS11 or HS12.
- if you use type C HS01 and SS01.
- which external ports are currently working fine, you will have to test them all at least for a moment with a UBS2 stick and a USB3 stick.
Anyway, if you dare to do it yourself, which is the best way to learn, here is the process as I did on my mobo, which is the same as yours.
