1.0.0.13 is from AMD win7 Graphics driver package 21.2.1

@canonkong
Thanks! Ryzen 5800X + B550 = NO PROBLEM Win7 ?

@Propretor
Except ASRock X570/B550. Others X570/B550 can work fine on win7.

@U_U
Before replace the hardware, you need to use DISM++ to add the driver package in, also you can use Dpinst to install the USB driver only.

@canonkong
I unpacked Radeon Software Adrenalin 2020 21_02_1 Win10 x64bit NON WHQL.exe
there are directories inside:
Audio
Display
RadeonLED
SBDrv
and there are no files in them amdRxhc.inf and amdRhub3.inf version DriverVer = 05/28/2020, 1.0.0.0013

@canonkong
What's the Difference
AMD_AM4_X399_TRX40_Drivers_B7_Win7_8.1_SHA256
AMD_AM4_X399_TRX40_Drivers_B9_Win7_8.1_SHA256
???
Sorry, but not clear.

@canonkong
Why files differ amdxhc31.cat amdhub31.cat amdxhc31.sys
in USB DriverVer=01/22/2018, 1.0.5.3
In my opinion, only these files should be supplemented:
amdxhc31.inf
amdhub31.inf

@Propretor
Unpack Radeon drivers for windows7, you can find amdRxhc and amdRhub3 drivers.

Vanilla amdxhc31.sys doesn't work on B550 chipset.
[Solution] Win7/8.1 Drivers for USB 3.0/3.1 Controllers of new AMD Chipset Systems (14)

@isopc1999a
OK, The AMD website constantly threw up the distribution kit for Win 10, and there was also for Win 7! The first issue has been resolved.

@canonkong
I want to be sure I understand correctly:
- with Dism++ I can only integrate the drivers into a Win 7 image to install it from scratch;
- with Dpinst I can install the drivers on a Win 7 installation already installed and running.
Hopefully someone can link me where to recover Dpinst and a guide on how to use it?
Thank you

Any AMD TR3 owners here using Windows 7 on daily basis?

I have an Asrock X570 Pro4 with the latest bios. I only found this forum after buying the board, so was annoyed to find these boards wont run Win7. Several threads discuss using a modified ACPI.sys, has someone got this to work? and can someone point me to a discussion of how they got this to work? Thanks

Just wanted to register and thank @canonkong and the rest of you guys for this thread. After having either non-working USB ports, bluescreens on startup or other issues trying to get this to work, I finally got my MSI B450M Mortar Max and Ryzen 7 3700X working with canonkong's USB drivers and all the ports I have tested so far are working without an issue.

In case anyone else needs this for the future, I'll just quickly outline what I did:

1. Use the MSI provided tool to make a bootable installation USB from my retail Win 7 SP1 disc.
2. Update to the latest BIOS (7B89v2C from 2021-02-01).
3. Install Windows using the USB memory and an old Creative Prodikeys PS/2 keyboard.
4. Install the basic chipset drivers from MSI's website (17.40.2815.1010 from 2018-07-06) and reboot. This got my USB mouse working, which helped a lot.
5. Install the Realtek LAN drivers from MSI's website (7.126.0510.2019 from 2019-07-30) and get my firewall+antivirus software installed.
6. Use Dism++ to install all the Windows updates that did not have any warnings or other notices on them. This required a couple of reboots.
7. Install the NVME updates (KB2990941-v3-x64 and then KB3087873-v2-x64) and reboot.
8. Use canonkong's USB driver (AMD_1.0.0.13_MOD_Win7) to fix the unknown USB devices in device manager and reboot.
9. Install the most recent chipset driver from AMD's website (2.04.28.626), but unchecking the USB driver from the installation, just in case, and then reboot.
10. Install the most recent GPU drivers for my 5700XT and other miscellaneous drivers for sound and such.

I did make a Windows restore point after every time consuming step, just so I wouldn't have to redo 30 minutes of work in case something went wrong along the way, but I have not had to use them this time around :)
Once again, thanks for the great drivers and good thread!

Or you can download the my new Windows 7 Service Pack 2.10 ISOs, I create the final ISOs bevore make the avaiable. The already have drivers for X570 and Ryzen 3000 integrated, (slipstreamed) into them.

@PatrickK, I did download and use that ISO (enWin7 x64_Pro_SP2.10) and put it on a thumbdrive via PowerISO to make a bootable USB. I have a MSI MAG x570 Tomahawk Wifi, Ryzen 7 3700x and MSI Radeon RX 580 graphics card with a TEAM 2T SSD. I have flashed the BIOS to the most recent. Like many other options I've tried, Win7 install always gets a Load Driver "a required CD/DVD device driver is missing" With your ISO as well.
I have tried adjusting things in the BIOS -
-Boot Mode: Legacy+UEFI
-Legacy USB support: enabled
-XHCI Hand-off: enabled
-BIOS UEFI/CSM MODE: CRM

The bootable USB is recognized, but I just get the missing driver for CD/DVD prompt every time.


I'm on page 20 of 34 in this thread, so far, so I don't know really if this has been definitively solved, I just saw your post with the ISO that should have what I need for my build and tried that.
I am not tech savvy enough to understand the OP instructions. What else can I do? I'm almost at my wit's end, as this new computer is for my business and my other one is crashing, old and can't really be updated anymore. I'm running out of time.

EDIT: I changed Legacy USB support - disabled, rebooted, then re-enabled it in bios, chose the bootable USB and it worked!! Win7 has successfully installed!

Thank you all for working so hard and being so responsive.

Hi Guys, i am new here and created a account because i need your help. I am using a ASUS B550-E Motherboard with a AMD 5900X CPU and want to install Windows 7 Home Premium (German). I used the drivers from @canonkong (first link) and the installation worked but after the first reboot all usb devices didnt work and i was unable to complete it. CSM and Legacy Support was activated in the BIOS. DSIM helped me to put the drivers into the boot and installation wim (all 4 indexes) but something must be wrong. @PatrickK iso didnt work too. Any ideas?
