Sample code hid/vhidmini2/

[harikvpy]

I'm trying to get the UMDF HID sample code working. While I can build the driver, I can't seem to install it. I get the error:

Device node created. Install is complete when drivers are installed...
Updating drivers for root\VhidminiUm from C:\Users\hari\greasehouse\learning\vhidmini2\driver\umdf2\Debug\VhidminiUm\VhidminiUm.inf.
devcon.exe failed.

Digging into setupapi.dev.log, I see this:

I have installed the test certificate to Trusted Root Certification Authorities and the Trusted Publishers certificate stores.

Could this be a problem with the INF file that is shipped with the sample?

Also, the "Creating WDF HID Minidrivers" document has a section that goes:

"Both MsHidUmdf.sys and MsHidKmdf.sys call the HID class driver's HidRegisterMinidriver routine to register as the actual HID minidriver. Although these drivers act as the device's function driver, they just pass I/O requests from the class driver to your driver (and are thus sometimes called pass-through drivers)."

However, I don't see any reference to HidRegisterMinidriver in the samle code. Since a UMDF HID driver is also a HID minidriver, shouldn't that too call HidRegisterMinidriver? If so, why is that missing from the sample code?

Any help will be appreciated. Thanks!
