Hi.
I am creating a WDM driver which uses WDF in order to access the WDF usb
functionality. I have successfully added the WDF coinstaller and am able to
load/unload my device. I am also able to create the WDF device using
WdfDeviceMiniportCreate(). This is based on msvad.
However, my call to WdfUsbTargetDeviceCreate() always fails with 0xC0000010.
I read and followed everything I could find regarding this subject. I don't
know what more to try so I'm hoping someone can help me. Someone who knows
what they are doing can probably tell right away why it's failing.....
Here is the debug output I am getting:

Routine Description:
This function is called by the operating system when the device is
started.
It is responsible for starting the miniports. This code is specific to
the adapter because it calls out miniports for functions that are specific
to the adapter.
Arguments:
DeviceObject - pointer to the driver object
Irp - pointer to the irp
ResourceList - pointer to the resource list assigned by PnP manager
Return Value:
NT status code.
