    - what does ClassGuid = {00000000-0000-0000-0000-000000000000} mean? [Version] signature = "$Windows NT$" Provider = %Company% ClassGuid = {00000000-0000-0000-0000-000000000000} DriverVer = 07/07/2008,1.0.0.1 CatalogFile = mydriver.cat If I have a classguid like the above,what does it mean.Is class and classguid entry in inf file mandatory. I was able to install the driver without the class entry in my inf file as mentioned above. but chkinf gives error if it doesnt find class and classguid entry in the inf file. may be my question is stupid but I couldnt resist asking.

    - USB device class question Hi What's the definition of USB group in Device Manager ? I see it have USB Controller or USB Hub driver or USB Mass Storage driver, I think these drivers are from different driver stack of USB , right ? Why USB mass storage device use "USB" class but not an independent class , I see USB Network card use "Net" class and USB Mouse use "Mouse". Thank for your teaching.

    - virtual device needs to allocate an interrupt I am working on a device driver that interacts with a custom hypervisor. The hypervisor can inject an interrupt into the guest OS (Windows Vista 64-bit) and my driver must handle it. The driver needs to request an available interrupt from the OS, and notify the hypervisor what interrupt vector to use during injection. I am new to Windows device drivers. My driver uses the WDF framework. I have created a custom bus driver that enumerates a single child function driver (I have used the Toaster example as the basis for my code). In the bus driverâ??s EvtDeviceResourceRequirementsQuery handler I add an IO_RESOURCE_DESCRIPTOR of type CmResourceTypeInterrupt. I really donâ??t care what interrupt vector to inject, so I specify the MinimumVector as 32 and MaximumVector as 255. My assumption is that the WDF framework will pass the resource requirements list to the PnP manager, allocate an interrupt that meets the above requirements, and pass it to my function driver in the EvtDevicePrepareHardware handler. However, when the bus driver enumerates the child function driver, after the call to EvtDeviceResourceRequirementsQuery I see a message in WinGDB: NTOSPNP:Unable to setup Arbiter and Translators The function driverâ??s EvtDevicePrepareHardware handler is never called. Obviously I am doing something incorrect. How can my driver reserve an interrupt that I could later use to interact with the hypervisor? P.

    - Replacing Printer Property Sheets Hello All, When we open the printer panel, select a printer and then right click and select properties, a UI pops-up with a number of (~7) tabs containing Ports, Device Settings etc. Is there any way I can suppress these tabs and instead display a single custom tab? Can this be done from plug-ins to the PScript/Unidrv core drivers? Or, do we need to write a core driver module in order to be able to replace these?

    - Make BIOS settings from Windows Hello! I would like to know if it's posible to make a setting in BIOS, from Windows. What I want to do is to set RTC Alarm, without entering in BIOS. I want to make this setting on several computers, that's way I don't want to make it manually on each computer. What I have in mind is to use a DLL with some API functions that could allow me to set this in BIOS from my application under Windows. Is this posible? Thanks!

    - KSMETHOD_TYPE_SOURCE: what it actually means I am trying to implement KSMETHOD on the AVStream mini-driver we developed. I would like to implement an asynchronous handling of the IRP passed into the methodhandler where data will be filled by the device into the output buffer through DMA (data will be in the order of megabytes). For this I believe that the output buffer should be directly passed into the driver, i.e. MDL for output buffer should be created with probe and lock. After going through KSMETHOD_ITEM>Flags member documentation I think it is done by the class driver but could not make out how to specify what I want. The confusion arise because of the way KSMETHOD_TYPE_SOURCE macro is explained. Whether setting it will lead to buffering? if so how source mode can then be enabled and when will the data be probed and locked? Hope someone has clarity on this. Thanks In Advance.

    - communication between wdf and wdm drivers. Hi, i have an architecture question regarding communication between a wdm driver and a wdf driver. my system holds an old wdm driver and a new WDF based driver. My product is going through a phase where these two drivers will need to communicate (until the old wdm will not be used anymore). i read some of your articles regarding driver-to-driver communication and i basically use function pointers (and interface notification for synch) and all works well. i started to face a problem when i try to do as follows : my WDF driver will be called with a pending IOCTl in order to fill some data and return it to the user mode part of that WDF driver. My WDM driver, however, is the one who's responsible for the interrupt handling. so - when an interrupt arrives, the WDM driver handles it and in its DPC will use function pointers in order to call a routine that is implemented in the WDF driver. here's where the problem starts : since the call comes from the WDM driver context i'm not able to use in that function any WDF calls. i get bug check. so my question is how would i be able to complete the pending IOCTL request in the WDF driver from a call in the WDM driver since i'm not able to use any WDF methods such as WdfCompleteRequest. does it seem right to use a work item in the WDF driver that would be signaled when the WDM driver uses the function pointer (a function that is implemented in the WDF driver which passed the function's pointer to the WDM driver) ? thanks, Kobi.

    - I/O target from socket doesn't timeout Hi, I have created an I/O target from a socket but when I send an I/O request to it, it won't timeout. The socket was created with WSASocket passing WSA_FLAG_OVERLAPPED and I used setsockopt() to set read/write timeout as below. After setting these options the I/O target is created using IWDFFileHandleTargetFactory::CreateFileHandleTarget. When I send down the request I specify a timeout of 10 seconds, but it won't work. Socket creation: socket = WSASocket(AF_INET,SOCK_STREAM,IPPROTO_TCP,NULL,0,WSA_FLAG_OVERLAPPED); Socket configuration: int iOptVal = 3000; res = setsockopt(socket, SOL_SOCKET, SO_SNDTIMEO, (char*)&iOptVal, sizeof(iOptVal)); res = setsockopt(socket, SOL_SOCKET, SO_RCVTIMEO, (char*)&iOptVal, sizeof(iOptVal)); I/O Target creation: IWDFFileHandleTargetFactory *fileHandleTargetFactory = NULL; IWDFIoTarget *target = NULL; hr = fxDevice->QueryInterface(IID_PPV_ARGS(&fileHandleTargetFactory)); hr = fileHandleTargetFactory->CreateFileHandleTarget(socket, &target); fileHandleTargetFactory->Release(); Request forwarding: request->Send(target,WDF_REQUEST_SEND_OPTION_TIMEOUT,-100000000); Has anyone had this problem? How can I set a timeout for a request sent to an I/O target created from a socket handle? Thanks in advance. Tag: WDM audio driver volume property with Subdevices Tag: 107489

    - I need a network miniredirector sample, NulMRx DDK sample doesn't Hi, I downloaded WDK 6001.18001. I built NullMRx sample and installed it. I tried it on WinXP and W2K3.. Unfortunatelly "net use * \\nulsvr\share" does not work. It returns with "System error 67 has occurred. The network name cannot be found." In init.c (Line 284) RxStartMinirdr function failed. It returns with "c000000e" (STATUS_NO_SUCH_DEVICE). I found this in the MSDN: "The call to RxStartMinirdr cannot be made from the DriverEntry routine of the network mini-redirector after a successful call to RxRegisterMinirdr since some of the start processing requires that the driver initialization be completed." But the RxStartMinirdr is called from DriverEntry. Could someone help me to solve this problem or give me a sample which works. Would be very important. Thanks, Misi.

    - Getting printer specific information stored in GPD file Hi all, Basically i have a custom UI and renderer plug-in for a printer driver using unidrv.dll. What i need to know in the plug-in are diffrent options set in the GPD file without reading(parsing) the GPD file. The only supported methods I found are in IPrintCoreHelper::GetOption which can give a feature - option return but not the particulars of that option. And the second method is IPrintCoreUI2::DrvGetDriverSetting which also given a feature name returns the selected option. The other close third is IPrintOemDriverUni::DrvGetGPDData which can only return the value of *OEMCustomData field. Is there a way to get other field from the GPD ?

    - DirectInput, USB HID filters, and EvtInternalDeviceControl I'm trying to write a filter for a USB HID device that will essentially override the device's HID Descriptors with a custom version, but otherwise function as a normal HID device. I've gotten the driver to compile, install, and execute but the EvtInternalDeviceControl function is never called. I've checked several of the KMDF samples and it appears I'm registering the function correctly. My EvtDeviceAdd and EvtDeviceD0Entry functions run, but nothing after. Further, will I need to do anything special in order to have DirectInput correctly recognize the device with the corrected descriptor? I'm using the hidkmdf HID minidriver KMDF sample as the function driver with this as my LowerFilter. I can post additional code and log data as needed. Below is the pertinent piece of my DeviceAdd function: WDF_IO_QUEUE_CONFIG queueConfig; WDFDEVICE hDevice; /* SNIP */ status = WdfDeviceCreate(&DeviceInit, &attributes, &hDevice); if (!NT_SUCCESS(status)) { DbgPrint("SIXCD: WdfDeviceCreate failed with status code 0x%x \n", status); return status; } WDF_IO_QUEUE_CONFIG_INIT_DEFAULT_QUEUE(&queueConfig, WdfIoQueueDispatchParallel); queueConfig.EvtIoInternalDeviceControl = SixcdEvtInternalDeviceControl; status = WdfIoQueueCreate(hDevice, &queueConfig, WDF_NO_OBJECT_ATTRIBUTES, WDF_NO_HANDLE ); if (!NT_SUCCESS (status)) { DbgPrint("SIXCD: WdfIoQueueCreate failed 0x%x\n", status); return status; } Tag: WDM audio driver volume property with Subdevices Tag: 107462

Problem: When i do the hardware scan with devcon, Add hardware wizard comes up, i want to supress that.

    - XcvData broken on Vista I have a print driver/port monitor pair that use XcvData and XcvDataPort to communicate. When the printer is being used as a network printer and connected to by a client, the driver on the client calls XcvData with a custom string in pszDataName. My XcvDataPort function in the port monitor recognizes this string and responds with the requested data. It's very simple, fully supported according to the documentation, and works flawlessly between XP boxes. But throw Vista into the mix and it's completely broken. If the server is XP and the client is Vista, XcvData returns error 2 (file not found). The port monitor on the server is *not* called. Conversely, if the server is Vista and the client is XP, XcvData returns error 122 (insufficient buffer). And again, the port monitor on the server is not called. However, despite the fact that XcvDataPort was never called, XcvData gives me back error 2 as XcvDataPort's return code. The actual printing works flawlessly in both cases, so I know it's not a fundamental permissions or network issue. It's purely a problem with XcvData. I strongly suspect it's a security issue since most things Vista are, but even if I turn off the firewall, UAC, print as admin, set permissions on the printer to full control for everyone, etc, I get the same results. It's as if Vista is simply refusing to allow XcvData to communicate with the port monitor. Any clues? Simplified code follows to give you an idea.... On the client I do this: // open the port on the print server HANDLE hServer; if (!OpenPrinterW(L"MyServer\\,XcvPort DIRPS:", &hServer, NULL)) return false; // request the data char *pBuff = new char[dataSize]; if (!XcvData(hServer, L"GetConfigData", 0, 0, (PBYTE)pBuff, dataSize, &dataSize, &status) || status != ERROR_SUCCESS) return false; On the server, the port monitor does this: DWORD WINAPI XcvDataPort(HANDLE hXcv, LPCWSTR pszDataName, PBYTE pInputData, DWORD cbInputData, PBYTE pOutputData, DWORD cbOutputData, PDWORD pcbOutputNeeded) { if (pszDataName && !wcscmp(pszDataName, L"GetConfigData")) { *pcbOutputNeeded = dataSize; if (cbOutputData < dataSize) return ERROR_INSUFFICIENT_BUFFER; *pOutputData = myData; return ERROR_SUCCESS; } return ERROR_SUCCESS; } Tag: WDM audio driver volume property with Subdevices Tag: 107448

My WDM Audio driver consists of up to 8 identical subdevices. I have
everything working with directsound and MM interfaces, except for
input volume control. I am getting property requests for volume in the
topology, but because the topology is at the device level there is no
information that I can find to tell me which of the 8 subdevices to
set the volume for. Does anyone have any insight into how to get there
from here? I thought maybe the MinorTarget would tell me, but its
always NULL.

Just for the archives, I got this all worked out after reading a
bazillion posts including one on www.wdmaudiodev.com.
The trick is I needed a separate topology for each subdevice.
