So how to deal with this bug? It’s unlikely that amd “fixes” this issue…

Bump… Does latest AGESA verisons fixed the problem? Can anyone confirm? Also is it possible to downgrade AGESA?
@Johannes_Krauser
MSI 5XX already fix this problem with the testing bios. Just wait for few weeks，maybe others will fellow.
Hi folks, recently got a Ryzen 3900X and an Asus TUF X570 to replace my old hardware. I’m trying to get Win 7 installed on an Intel Series 6 NVMe drive, however I’m struggling quite a bit. When I boot into Windows 7 setup, I’m unable to access any USB ports, including USB 2.0 ports connected to the motherboard header. I have a PS/2 keyboard so I didn’t think this would be a big deal, except I can’t access drivers via USB and thus can’t get setup to proceed using a USB stick. I figured out a workaround by using another HDD with the drivers on them, but whenever I try to load the USB drivers i get BSOD with STOP 1 (I read earlier in this thread that I need to install the chipset drivers first, but I can’t figure out how to do this). I tried to use a DVD instead and got to the point of selecting a hard drive, but the NVMe drive is not there and when I look for drivers in Canonkong’s folder, it doesn’t find anything. Do I need the Intel RST drivers instead? Would appreciate some help I’m up to my eyeballs in this stuff

Try these Windows 7 X470 chipset drivers for your X570 board, as a number of the chipsets are the same:

Also you might be interested in these Intel NVMe drivers:

Thanks ryegrass. I read that I could use the X470 drivers prior to starting all this but can’t open the .msi package as my workbench computer has an Intel processor. Is there someway I can get the standalone files to use during the Win 7 install?
@icelandicsamurai ,
I originally used the chipset drivers for the X470 version of my board (MPG X570 Gaming) by using DriverStoreExplorer to move my existing Windows 7 installation to the new hardware. Perhaps there is an X470 version of your board that would have the drivers you need.
Is it for both x570 and b550 chipsetes? This "fix" solve the bug you mentioned with zen2 and win7? So can I proceed and buy etc MSI mag b550m mortar?
has anyone got the wifi to work on win7? I’m on msi x570 ACE with the wifi6 ax200 and I can’t get it to install.
Also the latest USB driver version 4 wouldn’t install via device manager, but fortunately the older 2.0.0.49 did install.
What is the PSP driver? Do I need to install it? It’s not appearing in device manager at all, not even as something with a potential error.
@atemporal
Did you install the USB drivers using “amdRxhc_mod.inf” and “amdRhub3.inf” in “AMD_1.0.0.12_MOD_Win7”?
And, I’m not sure, but the current version of the PSP driver(AMD official) is dummy, maybe.
As for the AX200, there is no solution to the newer Intel WiFi/Bluetooth devices.
nope. I installed the AMD chipset drivers (official ones) then used device manager to update the unknown device drivers by pointing them to the 2.0.0.49 usb driver set. The 1.0.0.53 set from B4 wouldn’t install. Have I missed a step?
Realtek and intel LAN I was able to use official drivers. Still trying to find audio drivers for 1220 and HDA, bluetooth and wifi. Everything else behaving nicely including NVMe.
no ax200 drivers YET. It’s just a matter of time. It’s a bit fiddly as they rely on some win10 default drivers but slowly unpicking it. Not sure I’ll have the necessary skills to edit the .sys and dlls but will see how far I get. I’ve got the .inf files working but I’m guessing that;s the easy part.

First of all i would like to thank you so much for your great work!
Currently i am using TR1 1950x on x399 under Windows 7 x64.
And would like to know is it possible to run TR3 on TRX40 under the same Windows 7.
As i understand from your answer it is possible, right?
For this i will need mobo with CSM support. Is there any specific recommendations in terms of compatibility?
I am looking at Asrock TRX40 Taichi.
Hy guys, I am think changIng my Asrock X470 itx motherboard for to a MSI B550 ITX because of better memory overclocking. If i understand integrating the first page drivers into Win 7 iso, i will have working USB ports?

Even the USB gen 2 10 gbps port too?
I will do this motherboard upgrade only if i know my Win 7 will work…
Thank you for your work on these driver. I have a ASUS TUF Gaming B550-Plus mobo with Ryzen 7 3700X. I litteraly just upgraded to it August 24th. My mobo Doesn’t have a PS/2 port and I can’t even install Win7. With your updated pack slipstreamed into my Win7 install USB drive, will it work? Do these drivers cause any harm to the hardware?
I tried integrating latest drivers into my Win7 Ultimante ISO image. Install doesn’t detect USB devices, not even mobo USB 2.0 ports 
I miss Win7… 
If you’re using simplix’s updatepack7r2 for slipstreaming it to the ISO (just drag and drop the ISO to the update pack executable, the easiest way out). It should include the backported windows 8 usb3 stack by daniel_k, so you don’t need to integrate these usb3 drivers instead.
https://forums.mydigitallife.net/threads…ribution.45005/
for the usb3 stack itself if you want to integrate it manually: https://forums.mydigitallife.net/threads…-7-vista.81934/
Use Win7UsbPatcher from Asrock and it will give you USB mouse and keyboard working for the installation. Maybe not every USB port will work, you will need to check.
@CiroConsentino If ou want you can use my script that I wrote for integrating usb and other driver into an other Windows 7 ISO. Or you can use my already-done ISOs.
The reason is that the USB2.0-ports don’t work like traditional USB2-Ports, they are al provided by the same chip.
