Unknown device ACPI\MSFT0200 in Windows 10 Pro

I have an unknown device showing up in device manager of Windows 10 Pro- per the title MSFT0200

Hardware ID:

I have tried updating the BIOS to 3.03 and tried installing Windows 10 again, but this device still doesn’t find a driver.
I have downloaded and installed the latest AMD chipset driver set and video driver, still the same issue.
All other devices are fully identified with drivers loaded.

Have run Windows Update until nothing is left, tried “Update Driver” - Browse my computer and pointed to drive with AMD drivers and Windows install on USB with include subfolders checked.

Might be the AMD IPU. You really should not be using Windows 10 with the AMD Framework.

Could be Microsoft Pluton / TPM device? This is what I see Linux side:

Not the IPU, that is showing in device manager as a normal detected device.
AMD IPU Device:

I don’t think the TPM device, but maybe- since I don’t see a line for a TPM or Pluton device anywhere in device manager. That matches with device vendor “Microsoft”, but not sure why that would come under ACPI.

I will try a dual boot with Windows 11 and see if I can find the difference in the Device Manager listings.

Pretty sure it is the Microsoft Pluton security device. I had one unknown device when I was running in Windows 10 on my AMD Framework and it was that (it appears to only be supported in Windows 11).


Yes, after installing Windows 11, I can confirm that this device ID matches to the listing for Microsoft Pluton Processor under Security Devices.
Also missing from WIndows 10 device manager on the laptop is “Trusted Platform Module 2.0”.
On my desktop system running Windows 10, “Trusted Platform Module 2.0” does show up in device manager, so Windows 10 does support this, and the Frameworks laptop must also support it since it shows up with a Windows 11 install.
I will try to find more about TPM2.0 and having it active in Windows 10 on the laptop, then maybe also the Pluton device can become active.

If you can try and activate bitlocker with TPM unlock, every attempt failed in no TPM hardware found (or something like that) and the TPM management MMC snap-in said there was no TPM hardware found/available.

On my desktop, there’s an ACPI:MSFT0101 (not sure on the digits; I’m travelling and away from it) device that’s the AMD fTPM. I know because Linux complained about it being broken until I replaced it with an external TPM module.

The Pluton device provides TPM functionality, so if its not supported/available on Windows 10, you wont have TPM support.

I think the TPM requirement comes first. Installing Windows 11, I saw TMP2.0 show up in device manager before Pluton appeared.

I be perfectly happy to just disable the Pluton and keep using the machine. :slight_smile:

The Pluton device provides the TPM 2.0 functionality, regardless of how it appears in Windows 11.
If there isnt a device driver for Pluton on Windows 10, there wont be a TPM either, since its the same, single, device not 2 independant devices.

Having done some web searching, I am thinking there is an issue with the FW13 BIOS and Windows 10. For whatever reason Windows 11 has no trouble identifying and installing TPM devices, but Windows 10 without any change of BIOS settings does not identify the TPM as being present.
So, I am not going to spend more time, the only issue I see for other people could be if they install Windows 10 and then try to upgrade to Windows 11 they may have an issue as TPM is a requirement to do a Windows 11 upgrade (but this requirement can be bypassed with a bit of knowledge) . But doing a fresh Windows 11 has no issues.
I will just ignore the unknown device in Windows10, it shouldn’t affect operation.
Maybe a future BIOS update will let Windows 10 identify and install TPM 2.0?

Doubt it, it’s down to Microsoft or AMD to provide Windows 10 drivers for Pluton, and from what I can see, Microsoft consider it a Windows 11 feature only.
