Operation System: Windows Server 2016 R2
I have a RAMDisk driver can be installed with "Add Legacy Hardware Wizard" (hdwwiz.exe) successfully. From the output of devcon hwids *, the device can be seen as below.
ROOT\UNKNOWN\0000
Name: RAMDrive [ QSoft ] Enterprise (x64)
Hardware IDs:
ramdriv
However, I need complete the installation via Ansible, hence hdwwiz.exe cannot be used. It has to be done via command line without interaction.
I tried several approaches and none of them works.
C:\Ramdisk64_inst>devcon.exe install RAMDriv.inf ramdriv
Device node created. Install is complete when drivers are installed...
Updating drivers for ramdriv from C:\Ramdisk64_inst\RAMDriv.inf.
devcon.exe failed.
C:\Ramdisk64_inst>devcon.exe install RAMDriv.inf ROOT\UNKNOWN\0000
Device node created. Install is complete when drivers are installed...
Updating drivers for ROOT\UNKNOWN\0000 from C:\Ramdisk64_inst\RAMDriv.inf.
devcon.exe failed.

It ends without any error, but the driver is not installed.

It succeeded, but in fact driver is not installed.
None of them works. DpInst.exe says No matching devices found in INF, DevCon.exe says Unable to find any matching devices. It seems the same reason.
However the driver can be installed with hdwwiz.exe manually, does anyone know what is the secret inside hdwwiz.exe?
Legacy Drivers can´t be installed with pnputil and have to use LaunchINFSectionEx-Call
I tested the following and it works with several drivers from Windows 2000 up to Windows 10, 2012R2, 2016, 2019.
rundll32.exe advpack.dll,LaunchINFSectionEx ykmd.inf,Yubico64_Install.NT,,4,N
Pay attention to use the correct section
The correct section of the inf-File must be used, when there is no [DefaultInstall]-Section. This lacks in most answers. Look it up in your drivers inf-File and use the correct section (in my example "Yubico64_Install.NT"). Using the wrong section wont prompt an error. Im my example I use Quiet mode, no UI (4) and Never reboot (N) to install the driver automated via GPO. All options are documented in detail here:
