Welcome to AMD OS X

[AlGrey]

This guide will help you get native usb support for all USB ports on Ryzen motherboards. This will fix your issues with DACs/webcams/mics/BT dongles.

MAKE SURE THAT YOU HAVE A WORKING CLOVER ON YOUR USB DRIVE (usb installer you used to install macOS) AS THIS TUTORIAL CAN FAIL. BOOTING WITH THE CLOVER ON THE USB WILL MAKE THE USB PORTS WORK AGAIN (GenericUSBXHCI.kext is in /EFI/CLOVER/Kexts/**).

This patch replaces the old method : viewtopic.php?t=4736


Automated version (thanks XLNC) NOTE : not updated for mojave

Spoiler:

1. Open the Terminal app.

2. Run the command :

Code: Select all

curl -s -o ~/Desktop/ryzenusbfix.sh https://raw.githubusercontent.com/XLNCs/ryzenusbfix/master/ryzenusbfix.sh && chmod +x ~/Desktop/ryzenusbfix.sh && ~/Desktop/ryzenusbfix.sh

3. Let the script do its magic.

4. Reboot and enjoy

NOTE : If you don't have a functional USB port to operate your MacOS (not keyboard or mouse working), use your bootable AMDHS_installer or HighSierraAMD USB to boot to your installed macOS drive. That will allow you to use your USB ports temporarily . Then you can run ryzenusbfix to fix your USB ports and boot without the USB installer.

Manual version

Spoiler:

1. Delete GenericUSBXHCI.kext, DummyUSBEHCIPCI.kext and DummyUSBXHCIPCI.kext from:
a. EFI/CLOVER/kexts/10.xx or Other (xx is your MacOs version) NOTE : use Clover Configurator (Google it) to MOUNT your EFI folder.

c. Library/Extensions/

to me it does not work..
all USB port are disable
here is my iodump and patched DSDT and original DSDT and config.plist

X399 gigabyte gaming 7 f3g bios
1950x

[AlGrey]

@dygkset, Well not all of them are disabled. Just the ASMEDIA controller (PTHX). Try with this config below.

If not working, use the old patch. I added the patch (Ryzen USB patch [OLD]) to the repo, should show up. If not remove the repo and add it back again.

[ydeng]

What does the following say:
log show --predicate 'process == "kernel" AND eventMessage CONTAINS "USB"' --last boot

[wang0315abc]

Thanks so much for the tutorial, but it just won't work for mine It will disable all the usb port if I didn't put the GenericUSBXHCI.kext in the EFI folder.I use a 1950x with Asrock x399 Gaming Professional.Here is my output file, any help will be much appreciated .

[AlGrey]

@wang0315abc, clover patch is wrong. Should not be named AppleUSBXHCI 1, 2, 3.. just AppleUSBXHCI.

[wang0315abc]

@AlGrey,thanks so muchfor the help, and now some of the USB ports are activated,but not all of them, and the mouse is some kind of laggy, the wifi and bluetooth shows up but won't be connected, and after several tries I even can't boot into 10.13.3,I took 2 screenshot for the usb devices , is there anything I can do to fix this?Thanks again

[AlGrey]

report with all the files requested .. IOReg dump is more useful than a screenshot of that

[ydeng]

Here's a working version. No USB Simulation there.

Hi @AlGrey,

I was testing this out, and the ports on the front works fine

I have 1 issue though, but USB ports at the back of the MB aren't working with USB Hub (it works correctly if plugged to the front USB ports ). Attached are my logs / dumps and configs.
