    - Communication with driver Hi, I'm currently developing a user mode application that creates a rather big linked list which contains lots of structures that may contain linked lists theirselves. Now, how can I transfer this rather complex linked list into kernel mode? What's the best approach? Thanks a lot, Peter Tag: Virtual disk problem Tag: 91508

    - HP lagging in providing printer drivers for Vista my HP1012 laser printer does not work in Vista. I have posted asking for help elsewhere ... I am interested in reading opinions on why HP would be so slow in having printer driver support for printers on Vista. - the 1012 is no longer sold by HP but it is still relatively new. assuming HP is providing Vista support for the printers it sells, will it be difficult for HP to clone one of their working drivers to work with the 1012? - in general are printer drivers harder to write in Vista than XP? - has HP simply become a lame company that has little regard for its legacy customers? -Steve Tag: Virtual disk problem Tag: 91507

    - How to properly support an interface in an upper filter driver ? I am an upper filter driver and set & Enable an interface (IoRegisterDeviceInterface & IoSetDeviceInterfaceState() . Depending what stack this filter is on , the stacks below it will fail IRP_MJ_CREATE , some will succeed it. Some stacks depend on the IRP_MJ_CREATE , if filter completes with success , they are not happy. If the IRP_MJ_CREATE fails , user mode apps cannot access my interface, and value of filter. What is the proper method for supporting this ? Tag: Virtual disk problem Tag: 91506

    - USB Selective suspend support by Vista? Our device is a usb 1.1 low speed device with remote wake up capability. and it runs with the Vista in-box hid driver. it also passed USBCV suspend/remote wake up test, Well, after choosing maximum power saving policy in the Vista, we still can not obeserve the driver would send out the "set feature" command to enable the remote wake up function in our device. The deivce keep working on D0, and was not able to go into a power saving state. ""========= Per the ..http://msdn2.microsoft.com/en-us/library/ms793200.aspx In Microsoft Windows XP and later operating systems, the USB core stack supports a modified version of the "selective suspend" feature that is described in revision 2.0 of the Universal Serial Bus Specification. The USB selective suspend feature allows the hub driver to suspend an individual port without affecting the operation of the other ports on the hub. Selective suspension of USB devices is especially useful in portable computers, since it helps conserve battery power. Many devices, such as finger readers and other kinds of biometric scanners, only require power intermittently. Suspending such devices selectively reduces power consumption. More importantly, as long as any USB device remains powered, it will prevent the system from entering deeper sleep states, such as C3. The Windows selective suspend behavior is different for devices operating in Windows XP and Windows Vista. ""========== Once the device keep working on D0, it would prevent the CPU enter C3, it would result in the whole system consume more power.. Does anyone knows 1. The in-box HID driver in Vista support seletive suspend feature? 2. If yes, what's the requirement for arming the command to the device? Thanks. -chueh8 Tag: Virtual disk problem Tag: 91495

    - Multiple MiniportMessageInterruptDPCs on the same CPU In the following scenario, does NDIS call one MiniportMessageInterruptDPC per MSI message or just one DPC call? 1. The driver uses two MSI-X messages. 2. MiniportMessageInterrupt always sets QueueDefaultInterruptDpc to TRUE and returns TRUE. 3. The device sends one MSI message and interrupts a CPU. This causes a DPC. 4. While the last DPC is either running or is scheduled to run, the device sends a different MSI message and happens to interrupt the same CPU. Is this always going to result in another DPC because the interrupt is due to a different MSI message? Thanks... Tag: Virtual disk problem Tag: 91490

    - 1394 Debugging - So Close - Need Help I've set up my host and target machines for 1394 debugging. I have the virtual 1394 device drivers installed on the host machine and am able to connect to the target machine to begin the debug session. Right after the target's 1394 host controller loads, the debugging connection is lost. When I check the target's hardware properties, the 1394 host controller is whacked. I've read the documentation that warns to disable the target 1394 host controller before debugging with the caution "Be careful not to accidently disable the 1394 net adapter instead". The problem is, when I disable the 1394 host controller on the target, the 1394 net adapter disappears from the listing and thereby not allowing a debug connect at all. Any help would be greatly appreciated. Tag: Virtual disk problem Tag: 91488

    - IOCTL_SCSI_PASS_THRU commands in limited user mode Hi, Currently I am using IOCTL_SCSI_PASS_THRU commands in admin user mode, when logged in limited user mode I am not able to send IOCTL_SCSI_PASS_THRU commands to an USB device. The reason is Create file will fail due to Generic_read/Generic_write which is not available in limited user modes, and IOCTL_SCSI_PASS_THRU needs these options in DeviceIOControl. As I am working with USB Mass Storage device using usbstor.sys mass storage driver is there a method that would send same commands through USB end points or pipes. Also I found IOCTL_USB_USER_REQUEST which has USBUSER_PASS_THRU option but I could not locate any sample codes, i guess these are not documented. What I am trying to do is to send an vendor specfic command to an USB Mass Storage deivce. Thanks, JK Tag: Virtual disk problem Tag: 91485

    - machine hanging after reboot when enabling driver verifier When enabling the driver verifier and rebooting the machine (done automatically for some tests by DTM), the machine is hanging during the reboot. I can reproduce the problem also by doing the same thing manually (without DTM). I have Windbg attached and it seems the system is hanging at the very beginning: it seems the driver under test is not loaded yet, the last messages from windbg are "kernel debugger connection established", some stuff about symbol paths and "system uptime: not available" as last message. I'm only able to break into the debugger until after a very long time (more than 10 minutes). The strange thing is that I do not see the problem on all my test machines. I'm currently using 2 machines: the one which has the problem is a single-processor machine, the other one, which is a multi-processor machine, does not have the problem. Another difference between them is that the one with the problem has both XP and Vista installed on it while the other has only Vista installed. Both are 32-bit machines. Has anybody already seen this problem before or does anybody have suggestions to debug this problem? Thanks, Jeroen Tag: Virtual disk problem Tag: 91476

    - Tcpip.sys bug: FTP Upload. MiniportHalt isnt called untill it has returned all the outstanding sends. So, set up an FTP upload, then do a safe remove. Result, underlying USB bus driver gets the query remove and retuend INVALID_DEVICE_STATE for the Ndis miniport driver writes, but the miniport drivers Halt routine doesnt get called and the device doesnt get unloaded, hanging the PnP manager with device manager showing the device stil present. (You can tell the PnP manager is hung because an inserted USB stick isnt recognised). Via an applet and an IOCTL interface, the Ndis driver can be told to stop, whereupon it cancels all its send packets with a status of NDIS_STATUS_MEDIA_DISCONNECT. After this has hapened the miniport halt function does get called. So, from looking at the DDK: The PnP Manager issues an IRP_MN_QUERY_STOP_DEVICE request. On receiving this IRP, NDIS calls the ProtocolPnPEvent function of all protocol drivers that are bound to the adapter. In this call, NDIS specifies an event code of NetEventQueryRemoveDevice. If a protocol driver fails the NetEventQueryRemoveDevice event by returning a failure code from ProtocolPnPEvent, the PnP Manager might ignore the failure and subsequently succeed the IRP_MN_QUERY_STOP_DEVICE request (but it looks like it doesnt) ... After all protocol drivers are unbound from the NIC, NDIS calls the miniport driver's MiniportHalt function. So, it looks like tcpip.sys is failing the NetEventQueryRemoveDevice because it still has outstanding sends with the Nic driver, but the Nic driver cant complete them till its Halt function is called. Chicken...egg...chicken...egg. This is on XP SP2. I wonder if its 'fixed in Vista', like selective suspend ; ) Tag: Virtual disk problem Tag: 91474

    - Parallel Dispatching in KMDF drivers I have a PCI hardware with two communication channels. (A and B) Only DeviceIoControl() is used to communicate with this hardware, because there are In- and Outdata for each IRP. In NT4.0 driver I use the standard-queue for Type-A IOCTLs and a user-defined-queue for Type-B IOCTLs NTSTATUS MyDeviceControl(...) { ... switch(pIoStack->Parameters.DeviceIoControl.IoControlCode) { case IOCTL_MY_SIMPLE: // read some bits from hardware and complete IRP ... pIrp->IoStatus.Information=... pIrp->IoStatus.Status=... ntStatus=STATUS_SUCCESS; IoCompleteRequest(...) // no queue used break; case IOCTL_TYPE_A: ntStatus=STATUS_PENDING; IoMarkIrpPending(pIrp); IoStartPacket(...) // the default queue break; case IOCTL_TYPE_B: ntStatus=STATUS_PENDING; IoMarkIrpPending(pIrp); MyAlternateStartPacket(...) // my second queue break; ... } ... } -------------- Now I want to port my driver to KMDF. But I can define only one separate queue for Read, for Write and for IoControl. My Problem is, that I need two queues for IoControl like in my NT4.0 driver, because two User-Mode threads are communicating with my hardware (one thread with channel A, the other with channel B) Question 1: Is it possible in KMDF to return the IRP without using a queue (like IOCTL_MY_SIMPLE) Question 2: Can I direct my IRPs into different queues in KMDF? EvtIoDeviceControl is called for all types IOCTLs. (IOCTL_TYPE_A and for IOCTL_TYPE_B) Thanks Jacques Tag: Virtual disk problem Tag: 91437

    - Print Monitor Needs to Access Interactive Services I have a print monitor that is installed for a custom Postscript printer driver. This print monitor needs to display a screen asking the user to name a file and select some processing options during the call to LcmStartDocPort. It also invokes a COM object that display several interactive screens to process the file during the call to LcmEndDocPort. The printer driver and monitor installs and runs on OSes Win2K and up. It also installs on Vista, and it will properly interact with the user and process files as designed. However, on Vista the OS intercepts the dialog boxes and displays a dialog titled "Interactive Services Dialog Detection". The message is that "The program [my port monitor] may need information or permission to complete a task." When the user clicks OK, the dialogs are displayed. My questions: 1. How can I properly set permissions (programatically, during the installation) on the port monitor so that it can interact in the user session without the OS intercepting the dialog boxes? 2. Do these permissions need to be applied to the port monitor (a dll) or to the spooler that invokes it? Thanks, Mike Tag: Virtual disk problem Tag: 91436

    - Does Longhorn driver work for W2K3 or Vice Versa Hi, I'm porting my driver to Longhorn, it's a boot-loaded driver supporting W2K3 32bit, W2K3 x64 and W2K3 ia64. Now we need to support Longhorn on all 3 platforms. Since for W2K3 support, I've built 6 drivers (free/checked, x86/x64/ia64). If for Longhorn, I build another 6, that'll be a lot. My questions are: 1. If I use WDK to build a driver for Longhorn in WDK Longhorn build enviroment, could that driver run in W2K3 on same platform ? 2. As a boot-loaded driver, to support Longhorn x64, it needs a embedded signature in driver file. If I do so, could this driver run in W2K3 x64 ? Tag: Virtual disk problem Tag: 91390

I then decided to run some tests on sound card drivers currently used by computer on which I installed DTM client (this PC is running Windows XP pro if it matters). All these drivers are signed by Microsoft, so I expected that all test should complete successfully. Was my expectation wrong? Because they all failed. Looking at the test errors I see this several times: ================================= Failed to Wait For Autologon Error Code 0 (The operation completed successfully) Resolution Waiting for autologon in session 0 failed. If you have tasks depending on that session to be present then those tasks will fail until someone logs on to the session. ====================================== Does it mean that PC where DTM client is installed should be configured for Autologon?

    - VISTA Install Windows Drivers (Hardware-First Scenarios) I need to install drivers on VISTA and XP. I will provide a CD containing the drivers. As documented in the SDK and the WHDC site, I have added in my autorun.inf a new directive supported by VISTA, "hardwareid".

    - NDIS: ProtocolUnbindAdapter() gets called at IRQL DISPATCH_LEVEL on Vista I got a problem, where ProtocolUnbindAdapter() of my IM driver gets called at IRQL DISPATCH_LEVEL on Vista, consequently causing a bugcheck 0x7C with 0x14,0x02,0x00,0x00 parameters when calling NdisWaitEvent() to wait for NdisCloseAdapter() to complete asynchronously. I'd like to know, why this can happen (most likely it's my programming error, but still), if the documentation clearly states that ProtocolUnbindAdapter() is called at PASSIVE_LEVEL IRQL. Also, the Debugging Tools documentation must be updated probably, since it doesn't reflect 0x14 parameter in the 0x7C bugcheck documentation. Additionally, when I specifically enable "DbgPrint buffering" parameter in GFlags utility and reboot the system and it crashes with a full memory dump, WinDbg then displays nothing when issuing ! dbgprint command. The nt!kdprint* buffers are empty for some reason. Thanks. Tag: Virtual disk problem Tag: 91378

    - KMDF inconsistent compiling: order of struct { } members differs I'm writing a KMDF-driver with an IoCtl-Interface. For each IOCTL-code I have defined a C-structure which describes the data passed between driver and the application. These structures interpret the data buffer "inBuf" and "outBuf" on both sides of DeviceIoControl(). So I have several "typedef struct { ... } " declarations. These are located in a separate header .h-file, which is included both in the driver sources and the application sources. So it is garanteed that driver and applications use the same buffer-structures. PROBLEM: I have found at least one struct {}, where the compiler changed the field order, when he compiles the driver. Example: typedef struct { DWORD result; DWORD long_value; char string_value[MAX_STRINGPARAMLEN]; } MyRecord ; When I compile the APPLICATION and declare a variable "mybuffer" MyRecord mybuffer ; then the fields have physically those offsets: mybuffer byte 0..3: member ".result" mybuffer byte 4..7: member ".long_value" mybuffer byte 8..11: member ".string_value" = pointer to character-array = address of mybuffer byte 12 mybuffer byte 12 ... space for string This is as it should be: struct fields are allocate in the order they were defined. BUT when I compile the DRIVER, then there are those offsets: MyRecord mybuffer ; mybuffer byte 0..3: member ".result" mybuffer byte 4..7: member ".string_value" = pointer to character-array = address of mybuffer byte 12 mybuffer byte 8..11: member ".long_value" mybuffer byte 12 ... space for string So the order of members is NOT like defined, the members ".long_value" and ".string_value" were exchanged! The consequences are of course catastrophic, since the driver interprets the integer "long_value" as pointer to the character array "string_value" => end of live as we know it. Thanks for reading so far, I hope the problem is clear now. I searched a lot, but found no #pragma settings which could influence the ordering of struct-members. Only struct-aligning can be modified, but this is not my problem. Some more facts: - I use WinDDK 6000 - driver and application are compiled within the same run of the BUILD-utility - its a checked build for x86 and WinXP platform. - build environment is also an x86 machine with WinXP.

    - USB HID Lower Filter Driver issue under VISTA Hi, I have a problem under MS VISTA with a USB HID filter driver (I developped) attached as low filter on the USB common class generic parent driver (usbccgp.sys) for a USB keyboard device with extra keys. The goal of my filter driver is to change the behaviour or inibit some extra keys of the keyboard. The principle of the filter is the following: it change the HID codes output for the requested keys using a remapping table set in the registry (bytes of code to replace/ bytes of replacing code) and comparing incoming codes and replacing if codes are matching the ones for the keys. Inside the filter driver, the codes are catched thru IRP_MJ_INTERNAL_DEVICE_CONTROL IRP, then IOCTL_INTERNAL_USB_SUBMIT_URB control code, then URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER function. This filter driver works fine under Windows XP all version. But, now, under vista the filter is installing and running (i can see this thru debug outputs), but it doesn't filter anything: it doesn't catch anymore the function URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER even if i can see this URB with a sniffer (WDMSniffer). I am not a specialist in driver development and i don't understand what could have changed under Windows Vista comparing to Windows XP ? Does somebody has an idea?

    - Legacy driver class for "Unclassified Signature" program What class should I use for legacy non-pnp software-only driver? According to "Unclassified Signature" requirements, driver must be installed through an INF-file. I tried to use "LegacyDriver" and "Unknown" classes, but chkinf tool reports that these classes are for system use only. Is there the only way is to define own class and write class coinstaller? Thanks for assistance. Tag: Virtual disk problem Tag: 91365

    - How to remove default Layer 2 multicast addresses in miniport driv Hello, Upon examining the netvmini sample using OID scope, I found that there are default layer 2 multicast addresses, usually: 01:00:5e:00:00:01 01:00:5e:7f:ff:fa 01:80:c2:00:00:03 After further research, I found that the first two are used for IP multicasting, while the third is used for IEEE 802.1x port authentication. How can I remove these default addresses from the miniport multicast address list? Is it even advisable to do this? Tag: Virtual disk problem Tag: 91363

    - High level intermediary driver Hello, Are there any existing driver apps that could "bridge" to audio devices such that audio stream data can be fed to two devices (or more) at the same time? Particularly devices of different colors (hi def audio device and stereo output device or S/PDIF device) When accessed by an application to output audio data, it would appear as an audio device and then redirect and feed the data to multiple audio hardware devices... Thanks, Chris Tag: Virtual disk problem Tag: 91351

    - DTM network LAN Test Environment I got some question in DMT. Q1. In Local machine, Could Test device and Support device set in the sam e PCI Bus? Q2. While NDIS testing, could I change the test item order? Could I just select one subitem to test? Q3. I had already read the DMT's help, But I don't see how to set the subnet of remote machine's message device. My environment: DTM Controller and Studio + 1 NIC IP: 192.168.0.100 Local Machine + Test Device IP: 192.168.0.2 + Support Device IP: 192.168.0.3 + Message Device IP: 192.168.1.2 Remote Machine + Support Device IP: 192.168.0.1 + Message Device IP: 192.168.1.1 am I right? Could you offer the correct environment of the company which had gotten the submission? Q4. Could you offer the PC List which can test DTM Network LAN (Include X86 and X64)? Could you offer the PC List of the company which had gotten the submission? Tag: Virtual disk problem Tag: 91344

    - NDIS 6 RSS: mapping between CPU number, MSI message, and queue I am working on an Ethernet miniport driver, and am confused about RSS. Suppose the NIC has 16 MSI-X messages and it supports 16 receive queues. According to the NDIS spec, the NIC should compute the target "CPU" as follows. Target CPU = indirection_table[hash & (table_size - 1)] & (# of receive queues - 1) + base cpu number. Computing this target CPU number is straightforward. But, how should the NIC map this number onto a specific receive queue and also the MSI message to generate an interrupt? The indrection table entries as well as the base CPU number may change over time according to the RSS spec. How does NDIS know that the NIC is interrupting the expected CPU?

    - Accessing IO port Resource Controlled by Motherboard Resource Hi All, I need to access some of the IO ports of my motherboard to turn on some of the on-board LEDs. It looks like these IO port resources are controlled by the "Motherboard Resource" system device. Which is the best way to set/clear bits of this IO registers? Are there any articles available on accessing the resources controlled by the Motherboard Resouece? Thanks in Advance, Boby Tag: Virtual disk problem Tag: 91329

I'm trying to port my virtual disk driver to Windows Server 2003 SP1 running
on Virtual Server 2005 x64. I create symbolic link using DefineDosDevice. And
I get "X:\ is not accessible. Incorrect function." every time I try to access
created drive. My driver gets only IRP_MJ_CREATE.
Symbolic link is correct: x: --> \Device\Mydevice.
In CreateClose routine:
irp.Status = STATUS_SUCCESS;
irp.Information = FILE_OPENED ;
IoCompleteRequest(irp, IO_NO_INCREMENT);
return STATUS_SUCCESS;

Seems to be OK. I'v tried to call IoCreateSymbolicLink. Same promblem. Whats
wrong?

Does it work on the *real* Server 2003 SP1?

IMHO, a proper virtual disk does not need to create the symbolic link. It's
done automatically by the mount manager.
