[Guide] ‘Fixing’ Windows 7 USB support on Matisse / Ryzen 3000 / Zen 2 on X370/X470

Hosting the guide I made a while earlier here. My Ryzen 9 3900X works fine on Windows 7 in my old x370 board, however I seemed to have lost all my USB ports on the back of my motherboard since the on-die Matisse USB 3.0 controller is not supported on Windows 7 and has no drivers from AMD.

However, with a bit of hacky-whacky, I managed to get it working by tricking Windows 7 into using the Ryzen 1000/2000 driver anyway. I figured AMD wouldn’t have changed the on-die USB controller significantly. It should work on all pre-x570 motherboards, since the controller is standalone and on-die. Here’s how do it, however;

DISCLAIMER: This workaround is at your own risk. I have not extensively tested it except for that it now works and I’m typing this post in Windows 7 on the Matisse USB 3.0 Controller.

Now, without further ado:

—————————

Foolproof Matisse Windows 7 USB tutorial:

  • Plug keyboard/mouse in front-usb so you can navigate Windows 7
  • Download the latest AMD Chipset Windows 7 drivers from AMD: www. amd.com/en/support/chipsets/amd-socket-am4/x370
  • Start the installation such that the installer extracts its contents into C:\AMD\. You don’t need to finish the installation, but it can’t do harm either.
  • Browse to C:\AMD\Chipset_Driver_Installer\AMD_Chipset_Drivers\MSIFiles\program files\AMD\Chipset_IODrivers\USBController Driver\Win7\x64 and open ‘amdxhc.inf’ in notepad.
  • We’re going to trick Windows into installing drivers for Ryzen 1- and 2000 for the 3000 series. Find this block:

Code:

[AMD.NTamd64]  
%AMDXHCI.DeviceDesc% = AMDXHCI, PCI\VEN_1022&DEV_145C  
%AMDXHCI.DeviceDesc% = AMDXHCI, PCI\VEN_1022&DEV_15E0  
%AMDXHCI.DeviceDesc% = AMDXHCI, PCI\VEN_1022&DEV_15E1  
%AMDXHCI.DeviceDesc% = AMDXHCI, PCI\VEN_1022&DEV_145F
  • Change DEV_145C to DEV_149C, resulting in

Code:

[AMD.NTamd64]  
%AMDXHCI. DeviceDesc% = AMDXHCI, PCI\VEN_1022&DEV_149C  
%AMDXHCI.DeviceDesc% = AMDXHCI, PCI\VEN_1022&DEV_15E0  
%AMDXHCI.DeviceDesc% = AMDXHCI, PCI\VEN_1022&DEV_15E1  
%AMDXHCI.DeviceDesc% = AMDXHCI, PCI\VEN_1022&DEV_145F
  • Go to device manager, right click the unrecognized USB controller «Universal Serial Bus (USB) Controller» and choose «Update driver software»
  • Choose «Browse my computer for driver software»
  • Click «Browse» and direct it to C:\AMD, and make sure to check the checkbox «Include subfolders». It should now search for your modified .inf file. Alternatively, you can direct it all the way to C:\AMD\Chipset_Driver_Installer\AMD_Chipset_Drivers\MSIFiles\program files\AMD\Chipset_IODrivers\USBController Driver\Win7\x64
  • You will be prompted to install the driver software. Choose «Install anyway»

You’re done. USB works.

If anyone has guides how to slipstream these drivers into a Windows 7 installation image, and how to extend it to X570, let me know so I can append it to this topic.
