Hi, all

I am developping the HID minidriver for device (A). It contains USB hub and
another USB HID device (B) is connected. So I want to read data from device
(B) in one driver.

So I refered toaster sample and code the IoRegisterPlugPlayNotification()
for retreive the symbolic link name for device (B). I could get the symbolic
link name in PnP and WdfIoTargetCreate is successfull but WdfIoTargetOpen
fails 0x0c0000001.

Is this method right ?

Please advice.

------------------------------------
WDF_OBJECT_ATTRIBUTES_INIT_CONTEXT_TYPE(&attributes, TARGET_DEVICE_INFO);

status = WdfIoTargetCreate(deviceExtension->WdfDevice,
&attributes,
&ioTarget);
if (!NT_SUCCESS(status)) {
TraceEvents(TRACE_LEVEL_INFORMATION, DBG_INIT,
"WdfIoTargetCreate failed 0x%x\n", status);
return status;
}

targetDeviceInfo = GetTargetDeviceInfo(ioTarget);
targetDeviceInfo->DeviceExtension = deviceExtension;

WDF_IO_TARGET_OPEN_PARAMS_INIT_OPEN_BY_NAME(
&openParams,
SymbolicLink,
STANDARD_RIGHTS_ALL);

openParams.ShareAccess = FILE_SHARE_READ;
openParams.EvtIoTargetQueryRemove = HidEvtIoTargetQueryRemove;
openParams.EvtIoTargetRemoveCanceled = HidEvtIoTargetRemoveCanceled;
openParams.EvtIoTargetRemoveComplete = HidEvtIoTargetRemoveComplete;


status = WdfIoTargetOpen(ioTarget, &openParams);

if (!NT_SUCCESS(status)) {
TraceEvents(TRACE_LEVEL_INFORMATION, DBG_INIT,
"WdfIoTargetOpen failed with status 0x%x\n", status);
WdfObjectDelete(ioTarget);
return status;
}

does device (b) support file handles? what does !wdfkd.wdflogdump <your
driver name> say?

Thanks Doron

> does device (b) support file handles?

Device (b) does not have my driver and it is displayed as "USB Input Device"
on Device Manager. I can open the device (b) by CreateFile and read data from
the device (b) by user mode application, so I think it supports file handle.

> what does !wdfkd.wdflogdump <your driver name> say?

I tried to display but could not display it. ( Message : Could not retrieve
WDF log header for driver ).

By the way, I found article on release note on the WDK
(C:\WinDDK\7600.16385.0\relnote.htm), it says "KMDF filter driver for HID
device may fail to send I/O". Is it related issue ?

I want to combine the data from device (a) and device (b) without user mode
application.

Thanks.

Just to make sure, did you correctly set the TMF file before attempting to
view the log? The extension is !wdftmffile.
