Primitive driver INF not installable

NTDEV
1

Hi,
We’re moving our driver family from EWDK 2017 to 2022.
A single device-less driver is now “primitive”.

  • I made a new INF file according to
    https://learn.microsoft.com/en-us/windows-hardware/drivers/develop/creating-a-primitive-driver

  • It passes inf2cat without warnings.

  • When installing with
    Devicemanager / add legacy device / … / “have disk”
    I get a message (my german->english translation):
    "In the folder there is no compatible software driver for device.
    If there’s a driver in the folder, then assure it for “x64 based Windows system”.

  • However I have the “DefaultInstall.NTamd64” key, see below.

Thanks

You should be able to install this from Windows Explorer. Right-click on the file and choose “Install”.

I did before, it says “Operation sucessful”, but still isn’t responsible.
Solution: Set service start type to “0” = ON BOOT in Services-Registry.
After reboot I can contact my drivers interface … thanks!

However I still don’t see the driver …

  • neither in device manager (“show hidden devices” active)
  • nor with “devcon findall *”
  • nor in services overview (“sc queryex type=service state=all”)
    Which Windows-tool will show my primitive driver?

device manager and devcon both operate on pop devices (and thus the drivers that are installed on them). primitive (“legacy”) drivers. sc query type=driver will show primitive and pop drivers.

pnputil /enum-drivers will show it as well
