Virtual Smartcard Driver (kmdf) -> WdfDeviceCreateDeviceInterface?

I want to build a non pnp smartcard driver.

I just tried to followed the suggestions in the thread:
http://www.techtalkz.com/microsoft-device-drivers/296063-virtual-smartcard-reader-not-listed-scardlistreaders.html

That included starting with the pnp smartcard driver sample from the WinDDK
6001 and remove the pnp stuff. So I tried to uses the initialization
routines from the nonpnp kmdf driver sample (same DDK).

I stuck calling the essential function:
WdfDeviceCreateDeviceInterface(Device,&SmartCardReaderGuid,NULL)
which returns 0xC0000010, STATUS_INVALID_DEVICE_REQUEST.

Unfortunately I cannot find out why this happens cause the WDFLOG command
"!D:\WinDDK\6001.18000\bin\x86\wdfkd.wdflogdump TSBTCS"
returns: "Could not find TSBTCS in wdfldr client list"

From a newsthread I read something about non pnp drivers not allowed to call
WdfDeviceCreateDeviceInterface.
Is that true and can anybody give me a clue to come around this?

Bye the way the function SmartcardInitialize returns Success, but that
doesn't seam to help me at all.

Why not go PnP? any hardware drivers should be PnP since w2k, non-PnP drivers
touching the hardware are limited in support and can, for instance, disable all
power management on the machine.

yes, non pnp drivers cannot use device interfaces. if you just want to
write a virtual smart card, install your driver as a root enumerated smart
card. this will give you a pnp presence, but does not require your device
to be detected by any bus. you can use the devcon tool (devcon install
[...]) to create and install your driver on a root enumerated device.

Great, this is new to me, I thought: no ressource -> no pnp.=20

Thanks for that clarification to you and Maxim.

I just wonna state that this attempt works. I mixed some code of the
fakemodem DDK-sample with the smartcard sample. The driver is loaded
correctly in the device manager and I get the first IOCTL's from
SCardSvr.exe. Thanks again.
