 - 1394 - Set Speed For Async Read/Write/Lock Hello, is it possible to set the speed for a 1394 read/write/lock request? I'm encountering the problem that I can't access a device with an 1394B PHY and an older only S400 capable Link chip. Thus the PHY reports "I can handle S800 requests" with its Self Id Packets (which is correct): Packets between other nodes connected to this node can be S800. This makes sense. But the Link says "I can only up to S400" in the Bus Info Block. So I would expect the Windows 1394 driver to send S400 packets to the node. It doesn't. I sends S800 packets. So, again: Can I set the speed? How? And just for curiousity: Is MS doing wrong or is the device beyond the standard? Udo. Tag: Windows Logo Program Tag: 37103

 - devices interrupt sharing question Hi! How is it possible to point out does the PCI card support IRQ sharing or not. In Device Manager I can notice that USB HUB device and my PCI card share the same interrupt. I initialized the ISR for my card, but I forbided the instrrupt generating by my PCI circuit. Nevertheless the interrupts are still generated. And the device context is mine. Can anybody explain is it the right logic or not? And how can I avoid such situations, because when I process that interrupts and return TRUE the PC hangs up. Thanks in advance. Kiryl. Tag: Windows Logo Program Tag: 37096

 - Direct Music Synthesizer (Kernel Mode) Hello! I'm developping a Kernel Mode Synthesizer. I have first built the 'ddksynth' DDK sample. Everything is ok except that it doesn't work. Direct Music Synthesizer doesn't enumerate it in the Port Combobox. The last function called in the code is 'PropertyHandler_SynthCaps'. It seems that the system or DMProducer doesn't like something in the DDKSYNTH capabilies. Why? Does this sample work with WinXP (and DirectX 9)?

 - Build problem in w2k environment of 2003 DDK Hello, when I try to build my usb-driver in the w2k environment of 2003DDK I get the following error-message: BUILDMSG: Warning: The sample "C:\WINDDK\...." is not valid for the current OS target." No sys-File is generated. The same error occurs when I try to build the included usb samples from the ddk. On http://www.microsoft.com/whdc/ddk/relnotexpsp1.mspx I found the following: "When creating the Windows 2000 build environment using the Start Menu icon (or manually running %ddkroot%\bin\w2k\set2k.bat), the environment variable BUILD_OPTIONS is set in order to exclude many samples from default compilation under this environment. This has a couple of effects and limitations (which apply only to the Windows 2000 environment). - build -cZ from the root of the DDK now results in a clean build with no errors or warnings. - When doing the above, not all samples are built. - This does not prevent cd'ing into an arbitrary sample directory and attempting to build it. When doing so, samples that do not work correctly in the Windows 2000 build environment will still produce errors and/or warnings." Under W2K DDK my driver compiles fine, but I have read that is recommended to use always the latest DDK with the corresponding environment. Does anybody know how to fix this problem?

 - Resources problem Hi! I'm arookie in WDM and I have one question that I haven't been able to answer... I have a chip connected to a PCI bus in a Single Board Computer, for which I'm developing a WDM (Windows 2000) with the W2K DDK. Also I have been studying Walter Oney's book, and actually I used his wizard to produce a skeleton for my driver. Now the problem is that when I install this driver (or any other) to this chip windows says to me that I have a resorces problem with my I/O area, supposedly overlaped with the area of another chip (thing that is not true). So my driver is marked in the device manager as not working properly (yellow exclamation sign). So rigth now I can not open a handle to my device, and I'm not sure if it is because of this resorces reason or because of my handle routine. My objective in a short term is to be able to read and write to this device with the minimum driver requirements. Can you help me? Tag: Windows Logo Program Tag: 37083

 - Printer Driver Installation Hi, We have got our printer drivers for 98-NT-2k on a single CD. While installing the drivers for the USB in 2k OS it is displaying 98 OS inf files along with 2k OS inf files also. This problem was not observed earlier. We got the new cat file after WHQL certification. After replacing the new cat file with a dummy cat file this problem was observed. Steps to reproduce:- 1. Connect the USB printer to the 2k system 2. Windows will discover the new device ask for driver 3. Provide the CD path where the 98/2k printer drivers are 4. Select the -> search for best drivers option and check the CD rom as the driver path. 5. It will check the entire CD and provide the best driver inf. 6. Select (check)the Recommended other driver option and click on next. 7. This is displaying 2k as well as 98 printer drivers' inf files. It should only display 2k printer drivers. Could any body suggest me any changes required in the inf files so that 2k does nt recommend 98 drivers also along with 2k drivers. with warm regards, Chaitanya Tag: Windows Logo Program Tag: 37080

 - IoRegisterDeviceInterface? In Walter Oney's book 2nd ed Ch 2, section on registering device interfaces If a driver does not call IoRegisterDeviceInterface what are the implications? Is there a reason not to do this? I am working with a device multifunction usb where the modem interface is indeed registered but the diagnostic serial interface is not. Of course I used the sample from the WDM book for enumerating interfaces and used my own tool and this interface does not show up. I started this quest because I do not get notifications for this interface and it is killing me. ~mike Tag: Windows Logo Program Tag: 37071

 - Display driver responsible for system instability Not sure if here's the right place for this posting. Have tried other NG's, Microsoft and ATI with negative results. Basically... My system keeps locking up after a few minutes use. Message displayed after rebooting says 'Display driver RAGE 128 PRO Ultra GL AGP possibly responsible for system instability' also '... check with driver manufacturer for driver update' I've checked with Windows/Microsoft updates with negative result. I've looked at the ATI site and downloaded another driver for Windows XP. Message then says it's not compatible with my system - Windows XP. I've spent most of the last 48 hours trying to sort this problem and am nowhere nearer to a solution. My base unit is not overheating and my system is virus free. Currently I can only use computer a few minutes at a time before the whole thing locks. Can anyone assist please? Tag: Windows Logo Program Tag: 37065

 - wia driver under Windows 2k hi, there, I would like to ask a newbie question. I was reading msdn that WIA scanner driver can run under Windows 2000 if it exposes STI interface. Where can I find some information to do so? Also, in Windows XP DDK, I see that in a sample code (wiascroll), one of the classes is derived from IstiUSD, does that mean that I can use it under Windows 2000 for applications with sti interface.

 - To MmUnlockPages or Not? From what I gather, behind the scenes (there seems to be a lot of undocumented behind the scenes stuff) of a DeviceIOControl call (before coming to the driver) something takes care of calling MmProbeAndLockPages for some DIRECT IO IOCTL buffer. From the IOCTL dispatch routine in the driver to use it just like a normal buffer, you do MmGetSystemAddressForMdlSafe. Now say you take that virtual buffer you got from MmGetSystemAddressForMdlSafe and used it as a parameter to IoBuildAsynchornousFsdRequest -- Is something again behind the scenes going to do a MmProbeAndLockPages? Assuming it does, is it okay to use MmUnlockPages in the completion routine for the created IRP? Is it that it knows something else has them locked or does the additional MmProbeAndLockPages actually use additional memory locations? TIA!!! Tag: Windows Logo Program Tag: 37042

 - CD-ROM filter driver, take 3: Almost there... When I last reported my progress, I'd just gotten started on playing with James Antognini's sample filter driver code (thanks for pointing me to that, James!). I've managed to get the driver to do everything I need it to do at this point, but there's one problem that's come up that I can't make heads or tails of. (For those new to this, this is running on Windows 2000 SP4 Checked, built with Windows DDK 3790.) When I run my driver in bypass mode....everything is fine. No problems whatsoever, it's like it isn't even there. But when I put an encrypted disc in the drive and log it in, CDFS.SYS pukes thusly when it tried to mount the CD: kd> !analyze -v ******************************************************************************* * * * Bugcheck Analysis * * * ******************************************************************************* UNEXPECTED_KERNEL_MODE_TRAP (7f) This means a trap occurred in kernel mode, and it's a trap of a kind that the kernel isn't allowed to have/catch (bound trap) or that is always instant death (double fault). The first number in the bugcheck parens is the number of the trap (8 = double fault, etc) Consult an Intel x86 family manual to learn more about what these traps are. Here is a *portion* of those codes: If kv shows a taskGate use .tss on the part before the colon, then kv. Else if kv shows a trapframe use .trap on that value Else .trap on the appropriate frame will show where the trap was taken (on x86, this will be the ebp that goes with the procedure KiTrap) Endif kb will then show the corrected stack.

If I disable my decryption code, it also works (though plaintext is garbled, obviously). I've played with my completion routine to see if it's wild memory allocation or other funkiness, but everything I've tried so far seems to indicate that cdfs.sys doesn't like something the decryption code is doing. (The crash comes after it tries to mount, just after my completion routine returns STATUS_PENDING. Yes, I'm doing IoMarkIrpPending first, and yes, it usually works.) Anyone have any idea what's going on here? I'm completely stumped. Also, is there any way to get source for CDFS.SYS (even if it's in the IFS kit)? -lee Tag: Windows Logo Program Tag: 37037

 - turning the mouse pointer back on Hi all, Can anyone suggest a way to turn the mouse pointer back on after Windows has booted without a mouse plugged in? The purpose of this is to allow the computer to be remote-controlled without a mouse plugged in. I'm thinking that if this isn't possible, then it might be necessary to write an "empty" mouse driver that fools Windows into thinking a mouse is present during the boot sequence. There's got to be an easier way :) Cheers. Tag: Windows Logo Program Tag: 37031

 - OID_802_11_BSSID_LIST query from an application occassionally fails... I have a strange phenonemon in an application using the OID_802_11BSSID_LIST to scan the available SSID's currently available for the NIC. I use the following sequence: 1) The application binds to the WLAN adapter. 2) Then sets the adapter into ad-hoc mode using OID_802_11_INFRASTRUCTURE_MODE 3) then issueing the OID_802_11_BSSID_LIST_SCAN to make the NIC scanning 4) Finally, using the OID_802_11BSSID_LIST to extract the available SSID While on one machine using a 802b PCard NIC this sequence of OIDs work reliable, and has so far never caused the OID_802_11BSSID_LIST instruction to return an ERROR code. My second machine, has several NIC's available. However, I have only the ethernet NIC, a built-in WLAN NIC, and a PCard NIC activated. The others are deactivated. On this machine, the above described sequence of OIDs work most of time fine, say 80%, while the rest the last OID_802_11BSSID_LIST fails. When using the second machine with the built-in WLAN NIC the error code is 1784, whereas the PCard NIC in this situation returns an error code of 122. My questions: 1) Does anyone know about the reason my OID_802_11_BSSID_LIST call occassionally fails, and what means the error message 1784, and 122? 2) How can I myself, decrypt the error messages of such a call. Or in other words, is there some documentation of these error messages around? Thx, for your help Stefan PS: The PCard WLAN NIC are from Intersil, while the built-in card is an Intel card, and my program is running with XP SP1 Tag: Windows Logo Program Tag: 37017

I think kernel mode, is necessary for NT4 drivers (UI and Print Processor remain in user mode). Is this OK? I installed the driver under NT4 with install shield using AddPrinterDriver, AddPrinter and AddPrintProcessor-API. UI works fine, but when printing, NT4 says: "Cannot create a file when the file already exists" What is wrong?? Installation or NT4 Build ? Which symbols do i have to export in kernel mode? Can i use CPP-build? Do i have to use NT4 DDK with VC5? Many Questions! Any ideas? Thanks Stefan Please send answers also to: Stefan.Wanger@cib.de Tag: Windows Logo Program Tag: 37008

 - Why IOCTL_SERIAL_WAIT_ON_MASK request completed immediately? Hello everyone: I am working on a Nonepnp serial device driver for win2k. I think I have successfully attached my driver device object with serial driver device stack . And I have send the serial configuration IOCTL to next lower driver and got STATUS_SUCCESS response. I want to wait the serial port CTS state change, so I send the IOCTL_SERIAL_SET_WAIT_MASK request to the next lower driver. And then I try to update the serail modem status by send the IOCTL_SERIAL_GET_MODEMSTATUS. But this request always got the modem status == 0xFF. I think it must something wrong with it. What's the possible reason? After that I try to send the IOCTL_SERIAL_WAIT_ON_MASK request , but it completed immediately. ??? Here is some part of my codes: // // Start Serial Event Tracking // DeviceExtension->SerialConfigData.SerialWaitMask = SERIAL_EV_CTS; KeInitializeEvent( &Event,NotificationEvent,FALSE ); = IoBuildDeviceIoControlRequest( IOCTL_SERIAL_SET_WAIT_MASK, DeviceExtension->ReaderExtension->AttachedDeviceObject, &DeviceExtension->SerialConfigData.SerialWaitMask, sizeof(DeviceExtension->SerialConfigData.SerialWaitMask), NULL, 0, FALSE &Event, &IoStatus ); if (Irp == NULL) { return STATUS_INSUFFICIENT_RESOURCES; } status = IoCallDriver( DeviceExtension->ReaderExtension->AttachedDeviceObject, Irp, ); if (status == STATUS_SUCCESS) { KeInitializeEvent( &Event,NotificationEvent,FALSE ); WaitIrp = IoBuildDeviceIoControlRequest( Ioctlcode, DeviceExtension->AttachedDeviceObject, &DeviceExtension->SerialConfigData.SerialWaitMask, sizeof(DeviceExtension->SerialConfigData.SerialWaitMask), NULL, 0, FALSE, &Event, &IoStatus ); if (WaitIrp== NULL) { return STATUS_INSUFFICIENT_RESOURCES; } // We simulate a callback now that triggers the card supervision GetCTS( DeviceExtension->AttachedDeviceObject, WaitIrp,DeviceExtension ); } // //Used to track CTS events // NTSTATUS GetCTS(PDEVICE_OBJECT AttachedDeviceObject,PIRP Irp,PVOID DeviceExtension) { NTSTATUS status; ULONG ulModemStatus ; PIO_STACK_LOCATION irpStack; KIRQL irql; PSMARTCARD_EXTENSION pDeviceExtension = (PDEVICE_EXTENSION)DeviceExtension; ulModemStatus =pDeviceExtension ->ModemStatus; if(pDeviceExtension ->SerialConfigData.SerialWaitMask) { if(pDeviceExtension ->GetModemStatus)) //Variable used to receive the modem status { if(pDeviceExtension ->ModemStatus & SERIAL_CTS_STATE) { // Device Start } else { // Device stop; } // Setup call for device control to wait for a serial event irpStack = IoGetNextIrpStackLocation( Irp ); irpStack->MajorFunction = IRP_MJ_DEVICE_CONTROL; irpStack->MinorFunction = 0UL; irpStack->Parameters.DeviceIoControl.OutputBufferLength = sizeof(pDeviceExtension ->SerialConfigData.SerialWaitMask); irpStack->Parameters.DeviceIoControl.IoControlCode = IOCTL_SERIAL_WAIT_ON_MASK; pDeviceExtension ->SerialStatusIrp->AssociatedIrp.SystemBuffer = &pDeviceExtension ->SerialConfigData.SerialWaitMask; pDeviceExtension ->GetModemStatus = FALSE; } else { irpStack = IoGetNextIrpStackLocation(Irp); irpStack->MajorFunction = IRP_MJ_DEVICE_CONTROL; irpStack->MinorFunction = 0UL; irpStack->Parameters.DeviceIoControl.OutputBufferLength = sizeof(pDeviceExtension->ModemStatus); irpStack->Parameters.DeviceIoControl.IoControlCode = IOCTL_SERIAL_GET_MODEMSTATUS; pDeviceExtension->SerialStatusIrp->AssociatedIrp.SystemBuffer = &pDeviceExtension->ModemStatus; pDeviceExtension ->GetModemStatus = TRUE; } IoSetCompletionRoutine( Irp, GetCTS, DeviceExtension , TRUE, TRUE, TRUE ); status = IoCallDriver( pDeviceExtension ->AttachedDeviceObject,Irp ); return STATUS_MORE_PROCESSING_REQUIRED; } else { return STATUS_MORE_PROCESSING_REQUIRED; } } Tag: Windows Logo Program Tag: 36996

 - unidrv plugin internals question Recently I decided to venture into unidrv plugins internals. This is a basic question on unidrv plugins. What I see is unidrv plugin doesn't register in the registry. Thats right because there are scenarios when the plugin can't register in the registry such as in point and print case, wherein you can connect the printer on the server from a client. What I am observing is there are predefined classids An example is DEFINE_GUID(IID_IPrintOemUni, 0xd67ebbf0, 0x78bf, 0x11d1, 0x94, 0x80, 0x0, 0xa0, 0xc9, 0x6, 0x40, 0xb8); This classid is used internally in unidrv.dll. I have this "Windows 2000 OEM Unidrv Customization Sample" from ddk installed. Now the dependent file oemuni.dll has the component IOemUni with interface IPrintOemUni. Unidrv calls DllGetClassObject, creates a factory and then uses the factory to create the IOemUni component and then to retreive the IPrintOemUni interface. My question is very internal:- How is unidrv.dll detecting that which dll's DllClassObject to call to enable the creation of the plugin component? thank you vipin Tag: Windows Logo Program Tag: 36985

 - WDM Driver-MmUnlockPages Hi, In the PCI WDM Driver Iam using IoAllocateMdl(pData,buflen,..,pIRP) to get the MDL , lock the pages using MmProbeLockPages(pIrp->MdlAddress,..) and set the IRP to STATUS_PENDING and before queuing the request.In the ISR i am writing the pData to the device and once i am done writing i close the Irp in the DPC routine. I complete the IRP and make the IRP NULL,as there is no need to explicitly call MmUnlockpages .Is the approach correct or I have to free the locked pages.If so, where should i call MmUnlock pages.I am allocating the memory in the usermode application and call the DeviceIoControl using METHOD_IN_DIRECT/METHOD_BUFFERED.The memory size can be extended upto 4MB size. thanks sai Tag: Windows Logo Program Tag: 36975

 - Cleanup after IoBuildAsynchronousFsdRequest Oney's books has a loop to clean up the MDLs then the IoFreeIrp ... The MS samples have something like: if (Irp->MdlAddress != NULL) { MmUnlockPages(Irp->MdlAddress); IoFreeMdl(Irp->MdlAddress); Irp->MdlAddress = NULL; } So this generates two questions: 1) Is MmUnlockPages required in the completion routine of a IRP created with IoBuildAsynchronousFsdRequest? 2) Does IoFreeMdl take care of freeing all MDL's in the chain?

 - IRQL / Multitasking Question I can't find a straight answer to... If I'm running at DISPATCH_LEVEL (in a filter driver) and decide to create several irp's via IoBuildAsynchronousFsdRequest, setup a completion routine), send it down via IoCallDriver -- Is it at all possible that those requests could be serviced at all *before* I return from the dispatch routine returning STATUS_PENDING ?? (Even on multi-processor machines?) The concern being I need to release the original IRP when a counter setup in the original irp (passed to completion routine) is decremented to zero and don't want to add one have it complete before I add the next ones (if there was a next one).

 - Disk Filter for ME The Good news, my client was pleased with the changes I made to DiskPerf and is happily collecting statistics. The Bad news, now they want to do this on ME. Is there a reasonably simple way to intercept the disk I/O on ME and install a filter like this? Is there an example of doing something similar available? And yes I realize it's not going to be the same code as DiskPerf. Dave Tag: Windows Logo Program Tag: 36951

 - NdisAllocatePacketPoolEx et al question ... My W2K NDIS IM driver allocates a Packet Pool (with NdisAllocatePacketPoolEx()) and populates the pool with repeated/multiple calls to NdisAllocatePacket() during my driver init time. Thereafter, during the data-paths, my driver just uses a not-InUse, already allocated packet, from the pool. (I.e. I do not do NdisAllocatePacket() during the data-paths). I use NdisReinitializePacket() between uses of the same packet. The DDK says that I can use up to 0xFFFF descriptors in the pool (descriptors + overflow descriptors < 0xFFFF). But I currently allocate fewer than this. Question: Is it usual/common/expected practise to allocate 0xFFFF packets in such a pool? This seems to be "greedy", and potentially poorly utilize the memory in my server. But choosing a smaller number (say 4096) isn't always enough ... How have other drivers managed this? (I didn't see a good case study in the DDK samples ...). I suppose I could allocate 4096 and if/when I ever run out allocate another. This would slowly raise my high water mark towards 0xFFFF without doing so all at once at init-time... How have others addressed this issue? Just grab the max? Or left it to your customers to configure it in the registry? Or? Or? Any comments, suggestions appreciated, Thanks, ~Mark Tag: Windows Logo Program Tag: 36950

Hello!

I have developed a driver for digital firewire cameras. The cameras follow the IIDC spec.

Now I want to get a hardware logo for these cameras but the test fails because
the textual leaf resides in the Unit Dependend Directory of the device´s ConfigROM where
the test expects it to be in the Root Directory.

How do I get the HW and the driver logo´d? Has anybody successfully resolved a similar issue
with the winlogo team? And if yes, how?

Neither the WHQL email addresses nor the winlogo newsgroup offers a response to this
issue.

Thanks,

-Arne
