Re: How do you make a WDF driver create .Raw & .Translated resourc

But you will not be able to ensure that the key will be the same if you go
to another system.

Found it! With the WDF driver, the .Raw & .Translated resources are being
created as NTPNP_PCI0007.Raw and .Tranlated, instead of using <my driver
name>.Raw.

Well, I'm guessing the following code causes the creation, since the
resource
names are \Device\AcePciEx0.Raw, AcePciEx0.Translated, AcePciEx0_1.Raw
and
AcePciEx0_1.Translated, but I can't say for sure. Here's the code:

// create a device for each card found in the system: 16 buses max
for (deviceNumber = 0; BusNumber<16;BusNumber++) {
// keep going on this bus until we fail to find a card: 32 slots max
for (deviceNumber=0;deviceNumber<32;deviceNumber++) {
// null out our device pointers
for (ii = 0; ii < ACEPCIEX_CHANNELS; ii++) {
pAcePci[ii] = NULL;
}
// reset the device context for this class
acepciContext.pFirstDevice = NULL;
// create the correct number of this class
for(ii=0; ii<ACEPCIEX_CHANNELS; ii++) {
// create the device name: AcePciEx0,AcePciEx0_1...
deviceName = Concatenate(L"AcePciEx", deviceNumber);
if (ii!=0) deviceName += Concatenate(L"_", ii);
// set the class number in the context
acepciContext.ChannelNumber = ii;
// create the device object - CAcePciEx constructor
status = CreateDevice(
pDriverObject,
deviceName,
ACENT_DEVICE_TYPE,
pRegistryPath,
deviceNumber,
&(pAcePci[ii]),
&pDeviceObject,
(PVOID) &acepciContext);

I've got a legacy app that queries these resources to determine if
hardware
is present. Not my design, and not my app, I'm stuck with it.

My driver does have an EvtDevicePrepareHardware() callback, which
is
where
I
use WdfCmResourceListGetDescriptor() and MmMapIoSpace() to map in
device
memory. Problem is, /Device/MyDriverName.Raw and
/Device/MyDriverName.Translated resources are not created (under
\MACHINE\HARDWARE\RESOURCEMAP\PnP Manager\PnpManager) with the WDF
driver
and
I can't figure out what causes them to be created with the legacy
driver.

OK. Does anyone have any idea what triggers the creation of the
.Raw
and
.Translated PnPManager resources?
