    - Print a text string that uses True type font I need to convert True Type Font (TTF) to bitmap and then download it to the printer. Our printer drivers are a plug-in to minidrivers (PScript, UniDrv). Is there any documentation available that will help me accomplish the task? EngTextOut(...) is one API that I have in my mind but it requires surface, string, font object, How should I create or get these objects? Best Regards, Athar Tag: Where can I get SMBClass.sys?

    - One shot capture gives wrong DX GetStatus When I start capturing in DX with just DSCBSTATUS_CAPTURING (no |DSCBSTATUS_LOOPING) the GetStatus function is still coming back with the DSCBSTART_LOOPING state. I based the driver initially from the MSVAD sample and I am not clear where this distinction in startup lies. If you have an pointers as to were I could look to fix this I would greatly appreciate it. Tag: Where can I get SMBClass.sys? Tag: 72159

    - HPET support 1) Does Windows XP provide any support for accessing/using the High Performace Event Timers (HPET) in the chipset? 2) Will Windoes Vista use the HPET for QueryPerformanceCounter (both uni and multi-processor HALs)? 3) Does the Windows DDK offer any guidance on writing a driver for the HPET? I ask these questions because I'm looking for a high resolution timing solution to monitor performance of a multimedia app. I need a consistant, reliable timing base to compare against. 1ms resolution is not enough for my particular application.

    - Slipstreaming Device Drivers into a WIN2K3 installation I hope this topic is not to far from the purpose of this newsgroup. I am trying to install WIN2K3 on a new Dell 850 Server. I opted to buy an Adaptec SATA controller for $100 instead of Dell's for $400, but it may now be coming back to haunt me. The Dell Server Manager CD does not recognize the controller and I have been unable to get the drivers for this controller installed as the 850 does not support a Floppy drive. Can anyone point me in the direction of a good resource for slipstreaming drivers into a Win2k3 installation? Thanks Tag: Where can I get SMBClass.sys? Tag: 72152

    - Bulk and Iso-Transfers in one USB-Driver Hi all, I'm searching a reliable way to detect the pipe type of an IRP. I tried to read this information like Microsoft did in their Bulk Driver Sample from the DDK. In the dispatch routine I check for upcoming idle requests. Then I get the current Irp, the current file object, the pipe information and that's where I get the current pipe type from. I understood that every IRP stores information about what transfer type is at hand. Is that right? Depending on the pipe type I leave the dispatch routine forwarding the current Irp and device object to a validation routine for isochronous transfers (because they are more complicated) or bulk transfer completion routine. Isochronous completion is done as it can be seen the original sample. Microsoft did in their samples the validation for isochronous and both validation and transaction in the case of bulk transfers in the dispatch routine. Although I copied and pasted the whole algorithm from their (fine-working single) drivers, the system crashes when I try to perform a bulk/isochronous read or write. What rule did I violate? I'm through with W. Oneys book and the USB specification and the firmware and the application. Although this work is part of my internship and I'm (quite) new to this field I'm seriously trying to get the best out of my work. I appreciate your ideas very, very much!

    - DeviceIoControl() in WinCE Hi, I am writing a driver which takes in the call to DeviceIoControl() some structure like below: stuct someStruct { char *in_ptr; int in_ptr_len; int num; char *out_ptr; int out_ptr_len; } where ptr points to some memory. Problem is that DeviceIoControl() just seems to take a pointer to a buffer (in_ptr and out_ptr), so if now I passed address of an object of someStruct type, the how can I access data pointed to by ptr member from inside my driver? Also is it possible that i allocate memory pointed to by out_ptr in my driver and still I can access the memory from my application that opens that driver? I am using Pocker PC 2003.

    - Possible to write data to SMBIOS from ACPI operation region?? I have been reading the docs on ACPI operation regions and it seems that these regions are only useful for getting data from the BIOS, is this true? I have a need to access an SMBIOS interface which requires punching a physical address into a CPU register directly and then writing an I/O port. I was wondering if this interface could be converted to an ACPI op region and avoid all of the non-standard, non-WHQL approved kernel calls that are necessary to make this work? I notice that their are two access types listed for these regions "cooked" and "raw". The latest docs say "raw" access isn't implemented yet. I am guessing this is what would be needed for this type of interface yes? Originally, I was hoping that ACPI op region buffers were shared between BIOS and ACPI op region registrars, but it appears that the data flow is only one way, yes? Any pointers on how these op regions work and even better how an SMBIOS interface such as this could be accessed in a cleaner fashion would be much appreciated. BTW, for the sake of discussion assume I can modify the BIOS at will. Bill M. Tag: Where can I get SMBClass.sys? Tag: 72140

    - Hibernation problem for USB device without ROM firmware We make use of a USB device that gets its identity changed dynamically after the firmware is downloaded by our driver. The device has a unique VID and PID that is used for the two sets of drivers. The first VID & PID are burned into the ROM and it is not the USB chip manufacturer's VID/PID. I have searched through the archives and found a similar issue discussed along with a workaround suggested by Microsoft. (Attached below) Our device is not quite as schizophrenic since it has our own VID/PID before the downloading of firmware. Anyway, I preferred to test the second design for hibernation so I created a compound device with a hub. I installed a lower filter driver to our hub and tried to download the firmware during power up, but I found that the request (IOCTL_INTERNAL_USB_SUBMIT_URB with URB_FUNCTION_VENDOR_DEVICE) fails with STATUS_DEVICE_POWERED_OFF when I download the firmware before calling PoCallDriver (this is an experiment and what I expected). Also I get STATUS_DEVICE_NOT_CONNECTED when I download the firmware after PoCallDriver and this is not what I expected. It seems to me from my experimentation that this is not a realizable solution. I realize this suggestion was made "AS IS", but I was wondering if the concepts have ever been tested or what I might be missing? --- the following is the workaround --- Newsgroups: microsoft.public.development.device.drivers From: "Eliyas Yakub" <eliy...@microsoft.com> - Find messages by this author Date: Wed, 22 May 2002 12:16:04 -0700 Local: Wed, May 22 2002 3:16 pm Subject: Issues with schizophrenic devices (fyi) Reply to Author | Forward | Print | Individual Message | Show original | Report Abuse I brought to our PNP developer's attention nasty driver design issues people are running into with reprogrammable PCI (FPGA/DSP) and USB devices. We saw couple of those in recent days (Triggering a PCI bus re-scan) in this forum. Here is his response: ********************** Our customer needs to be warned that this type of hardware may not be productizable. The design (a reprogammable PCI FPGA chip that disappears and reappears as another device) is similar to some of the USB programmable DSP designs we've also seen problems with. Both of these designs run into major problems with PnP and Power Management. Problems -------- Identification - In its default state, the device usually exposes generic "DSP/FGPA" IDs. An INF targets those IDs and specifies a driver that'll transform the hardware into something else. If two different hardware vendors each use the same reprogrammable chip, their INFs will both match against the same DSP/FGPA IDs. The OS doesn't know which driver to pick. Even better, insert a card from each vendor - mayhem ensues as one of the cards will get the wrong payload. Power Management - During power management operations (hibernation, suspend, etc), all power is often removed from the chip. When this happens, the chip typically loses its new identity and reverts back to its DSP/FPGA form. To the OS, this appears to be a surprise removal (the card disappeared). All the handles opened by applications against the device will go dead. The application might reestablish contact when the original device appears to be "reinserted", ie the load sequence has repeated, but there is no gaurantee of this. Plug and Play - Some Plug and Play operations may result in power loss (rebalance), leading to the problem above. Updating the driver also temporarily places the hardware in D3. Depending on the bus, this may result in a state loss, causing the device to "disappear" just as the OS is planning to reload the new drivers. A reboot popup may result from this. How To Make FGPA/Reprogrammable-DSP Designs Work ------------------------------------------------ The best designs simulate a bridge/hub with devices behind it. For instance, the following design of a PCI FGPA works properly with Windows: 1. The PCI FGPA simulates a PCI-to-PCI bridge. 2. The PCI FGPA logic retrieves the IDs for the bridge from an EEPROM, ensuring no possible overlap with other customers using the same chip (the IHV is expected to contact the PCI SIG and retrieve such IDs.) 3. The INF for the FGPA specifies PCI.SYS as the FDO (using NEEDS and INCLUDE directives to reference machine.inf as needed), and specifies a lower filter driver that will deliver the payload. 4. During IRP_MN_START_DEVICE, the filter driver downloads the payload to the FPGA. The FPGA now appears as a bridge (same IDs) with a *child* behind it. The child represents the IHV's device. 5. After start, the OS enumerates the bridge. Since the child is present, the OS loads the next set of drivers. 6. During powerup from suspend or hibernation, the OS first powers up the bridge. The filter driver takes this opportunity to reapply the payload if necessary. Here is a similar design for a reprogrammable USB chip: 1. The USB chip simulates a hub. 2. The USB chip retrieves the Vid/Pid IDs for the hub from an EEPROM 3. The INF specifies USBHUB.SYS using NEEDS and INCLUDE directives targeting USB.INF. The INF also specifies a special lower filter driver to download the payload. 4. During IRP_MN_START_DEVICE, the filter programs the USB chip to appear as a hub with a device behind it. 5. After start, the OS enumerates the hub and discovers the child. 6. During powerup, the OS always powers up the hub before the child. The filter reapplies the payload during hub powerup. And another USB design: 1. The USB chip simulates a *composite* USB device. 2. The USB chip retrieves the Vid/Pid IDs for the hub from an EEPROM 3. The INF specifies USBGCCP.SYS via NEEDS and INCLUDE directives (similar to above). 4. During IRP_MN_START_DEVICE, USBGCCP will read descriptors from the hardware to determine which functions are exposed by the composite device. The driver (a lower filter) would reprogram the hardware to specify child during Start, before the IRP reached USBGCCP. 5. During powerup, the driver would reapply the payload as needed. -- -Eliyas This posting is provided "AS IS" with no warranties, and confers no rights. Tag: Where can I get SMBClass.sys? Tag: 72127

    - printer port monitor question re: drag-n-drop install I've got a question about port monitors and drag-n-drop printer installation. When you drag a printer from a server to a workstation, what happens to the port monitor that the printer driver(on the server) is using? Fron the printers folder, clicking on the printer's Properties/Ports tab shows the printer on the workstation is using the same port as the printer on the server is using. However, if you do File/Server Properties from the printers folder and look at the ports tab, the port is nowhere to be seen. If it's a non-standard port monitor (ie, not included with windows), the port TYPE isn't even there. (and you can't configure the port) So what port is the workstation printer actually using? Is this documented anywhere? I am especially interested in any information regarding user-written port monitors in this situation. Thanks, ScottR -- Scott Robins Tag: Where can I get SMBClass.sys?

    - Q: USB SCSI, announce media change? Ok, I couldn't find a better place to post this question, so here goes! I'm writing code for a device that exposes a removeable media drive. So far, no problems getting Windows to see the drive, notice that there's no media, etc. - however, when I change media Windows will redisplay the contents of the old media! I'm returning a CHECK_CONDITION with a sense code of 0x28 and a qualifier of 0x00 to TEST_UNIT_READY, which based on my reading of the SCSI spec should tell Windows that the media might have changed.. but Windows won't reread the device directory. Is there something else I should be returning here? TIA for any assistance, this is driving me nuts! Tag: Where can I get SMBClass.sys? Tag: 72113

    - USB (Camera) Device Driver. We are working on USB device driver for camera. We are facing problem in accessing data through video pipe (or Interrupt pipe) using bulk transfer. URB is built using UsbBuildInterruptOrBulkTransferRequest. All the three flags InvokeOnSuccess, InvokeOnError and InvokeOnCancel are enabled while setting callback function using IoSetCompletionRoutine. But USBD is calling the callback function only on InvokeOnCancel. In other cases were URBs are built using UsbBuildGetDescriptorRequest, USBD_CreateConfigurationRequestEx or UsbBuildSelectConfigurationRequest, the callback function is called on InvokeOnSuccess. Following observations are made. 1) The return value (NTSTATUS) of IoCallDriver is STATUS_LICENSE_QUOTA_EXCEEDED (not error), indicating status pending. This return value is observed in some other cases also but after sometime the callback function is called on InvokeOnSuccess. But in case of URB created using UsbBuildInterruptOrBulkTransferRequest, the callback is not called unless IRP is canceled (InvokeOnCancel). 2) Buffer is filled with some standard data before calling IoCallDriver and observed that the data is not changed, indicating that no data is obtained. This observation is made when the callback function is called on InvokeOnCancel. Since only while building URB using UsbBuildInterruptOrBulkTransferRequest we are using pipe details, we concentrated on the pipe details and concluded the following, 1) Pipe handle is valid. 2) Buffer is valid and is of proper size. 3) Current transfer size is proper. 4) Transfer flag is also proper. Is there anything we are missing to check? I am confused in concluding where am I going wrong. Is there anyone, facing the same problem? Any help will be grateful. Thanking in advance.

    - Not seeing "cancelled" status when I cancel my URB I have a (high-speed) USB driver which generates multiple isochronous urb's and queues them up, one after the other, through IoCallDriver() with a Completion routine set and all three flags (Success/Error/Cancel) set True. On certain conditions I need to cancel all these URB's; I happen to have kept a list of the requests so I can either call IoCancelIrp() on each or just do a URB_FUNCTION_ABORT_PIPE on the pipe. In either case, I don't see a STATUS_CANCELLED on the Irp when the completion routine is called on the outstanding transfers [I do see STATUS_DEVICE_NOT_CONNECTED if I yank the cable]. These transfers are entirely internally-generated - there's no upper layer Irp's involved in this. Now its possible that the 'cancelled' Irp/Urb's have in fact completed successfully by the time I do the cancel, and that this is why I get zero status - I'm not sure how to prove/disprove that idea right now. But I wondered if there was anything else I might have overlooked/misinterpreted? Thanks. Tag: Where can I get SMBClass.sys? Tag: 72081

As I want to make the packet inspection in user-mode, my question is: How can I make the communication bewteen the driver and usermode app? I need to signal the usermode that a packet has arrived, usermode must get the packet, kernelmode must queue the packet, usermode must pass its descision to kernelmode. I am experimenting with pending ReadFile to fetch packets. I have read that using events or shared memory are possible solutions. However, I am quite unclear which method is best suited for this purpose. Thanks, Chris Tag: Where can I get SMBClass.sys? Tag: 72074

    - Cause of implementation of IF(totalLength < packetSize) in DispatchReadWrite() of ISOUSB-Sample Driver Greetings. The sample driver leaves at this query in DispatchReadWrite routine while I am trying to send packets of 18 B whereas the packet size is 64 B. I don't get the idea why the pipeInformation->MaximumPacketSize returns the value of 64 B. Should it indicate a false structure length in my user-mode application or a firmware readout of my controller, which implements a value "packet size buffer" of 64 B. I appreciate your help!

    - Regarding USB drivers and firmware, or need to write one. Hi. A while ago, I assisted a company in writing firmware for a Cypress SX2 (Usb 2.0), plus a WDM driver for Windows 2000. The usb descriptor contains one configuration and two pipes; one for IN traffic, and one for OUT. Both use the BULK transfer method, and the driver methods are implemented as custom IOCTLs. Now, the same company report problems with this driver when shutting down the machine, plus some blue-screens now and then. When I wrote the driver, I knew very little about power management and plug 'n play.. and I suspect the problem is related to that. Also, they want the device to be compatible to usb 1.1. Now to my questions. Since I have complete control regarding the firmware, I'm considering conforming to a standard descriptor, i.e something like HID, to avoid rewriting/debugging the driver. The device should have a fairly "steady" stream of data on the IN pipe. The OUT pipe is used for setting commands. What kind of "HID" device do you recommend for this purpose? Can the the device enumerate as both a 1.1 and 2.0 when using a standard HID-driver? Is it difficult to "parse" OUT reports in firmware, sent by the "HID" driver? Another solution I'm considering is to remove all pnp- and power-code, make the driver incompatible with wdm, and instead load the driver manually as a service (no registry tampering, no infs). Have anyone there done that (with a usb driver)? Regards, Frank Tag: Where can I get SMBClass.sys? Tag: 72047

    - Retrieving Devices From The Registry I am a forensic investigator and trying to narrow down some information from the Windows registry on how Windows deals with connected hardware. Under HKLM/System/ControlSetxxx/Enum Windows lists a number of keys (e.g. IDE, USB, USBSTOR) under each of these there are devices listed (e.g. IDE you have IDE drives listed) what I am trying to find out is how Windows deals with these keys. I see some drives listed under IDE (e.g. CD Drives) that I have not connected to this machine at any time. Anyone who can shed some light on this part of the registry and how it is deal with I would look forward to reading it. Thanks Tag: Where can I get SMBClass.sys? Tag: 72030

    - MS-Paint will not finish during printing Hi, I use DrvCopyBits in my printer driver to print image data. In Word or Open Office the image is send correctly to printer. If I print a image from MS-Paint the page will be printed (passed through DrvCopyBits). The function returns TRUE for correct handling as result to GDI. My problem is, that the priting will not finish. The driver continues to print pages. Maybe someone knows tze reason?!? Thx. Tag: Where can I get SMBClass.sys? Tag: 72024

    - How to access the display adapter I2C bus? As I understand it, most display adapter drivers today can communicate with a monitor over the VGA/DVI cable using the I2C bus. Using the I2C bus you can send certain commands (VESA Monitor Control Command Set) to the monitor and, for example, set the brightness value or read EDID. On MSDN there is information on an I2C interface that the video miniport driver can access by calling VideoPortQueryServices. This interface contains routines with which communication on the I2C bus between the display adapter and the monitor is possible. How would on go about to access this interface, not being the video miniport driver? I am currently experimenting writing a custom kernel driver to do this. Is it possible to have a custom monitor driver which communicates directly with the monitor on the I2C bus, and have this driver export an interface to user mode? /Peter KorsbÃ¤ck Tag: Where can I get SMBClass.sys?

    - How to send IRP_MN_QUERY_INTERFACE to the USB Port Driver? Hello In the Windows DDK is stated that "vendor-supplied bus drivers can directly access interfaces exposed by the port driver.". To do this the driver has to retrieve a USB_BUS_INTERFACE_HUB_V5 (0..5) interface. "The bus driver can obtain this interface by sending an IRP_MN_QUERY_INTERFACE request to the port driver, with ...<irpconfig>..." How can I send an IRP_MN_QUERY_INTERFACE to the USB Port Driver? The driver has to IoAllocateIrp an IRP and then call IoCallDriver. But to call IoCallDriver (and to setup the IRP StackSize) a reference to the PortDriver is needed. Right? IoCallDriver expects a PDEVICE_OBJECT. How can I get the PDEVICE_OBJECT of the Port Driver? Maybe with IoGetDeviceObjectPointer. But what is the ObjectName of the Port Driver? Thank you! pascal Tag: Where can I get SMBClass.sys? Tag: 72013

    - reading/writing config space for any/all devices Hi, I'm updating a application that allows a hardware tester or developer to read or write the config space of ANY device on the system. Currently this is done with the HalGetBusDataByOffset function. I would like to replace these obsolete functions. I've read the threads on this forum on the topic but don't see an answer. I've also read this article: http://hollistech.com/Resources/Misc%20articles/getbusdata.htm Can I only do this by being the an upper filter driver of pci.sys? Thanks, any help would be appreciate.

    - Error on x64 removing device from installation program This isn't related to a driver per-se, but this group is probably the best one in which to ask the question. I have an installation program that I use for our drivers. As part of the removal, or prior to installation, it tries to remove the devices that match items in our INF file. On Windows 2000 and 32-bit Windows 2003 x86 it works fine. But on 64-bit Windows 2003 x64 it fails. The specific call that fails is SetupDiCallClassInstaller with an InstallFunction value of DIF_REMOVE. GetLastError returns 0xE0000235. I can't find any indication as to what this code means, and there seems to be no string corresponding to it available from FormatMessage. Note that this happens whether or not our driver is loaded. So with no driver installed, and a fresh system boot, this happens. Can anyone offer a suggestion as to what may be going wrong? Thanks, Nathan Tag: Where can I get SMBClass.sys? Tag: 72003

    - StorPort kernel function restrictions Hi, I am trying to understand what restrictions exist in a storport miniport driver with regard to what kernel functions can be called. Specifically, I would like to know if the only legal functions that can be called outside of the driver are the StorPort* functions; or can other standard Windows kernel functions be called like the Ke*, Ex*, Rtl* functions (our development is on Windows Server 2003). We asked technical support at Microsoft this question, and they said that we are strictly limited to calling the StorPort functions to get WHQL certifcation. But I don't see anything in MSDN that states this, nor have we found an HCT that validates that only "legal" functions are being called. Also, some of the sample code in the iSCSI DDK (wmisample.c) seems to use several kernel functions outside of the StorPort API. Does anyone know what the real restictions are, especially with regard to WHQL certifaction? Thanks, Tom Tag: Where can I get SMBClass.sys? Tag: 72002

    - Help Testing Driver Hello, I am trying to test a driver using VB. Here's the situation. I got the WinIO drivers from www.internals.com in order to access I/O ports on a Win2K/XP machine. I created a C++ dll that access the WinIO driver for reading and writing to ports. The function that do the I export so that a VB app can call them. I created a test VB app that calls a read function. When I try to run the VB app from the VB IDE I get the error "cannot find MyDLL.Dll" (my dll, not the WinIO dll's) when calling the function. But when I create the .exe for my VB app everything works fine. The program runs and the functions get called correctly and return the expected data. Why does the VB IDE fail whereas the .exe runs? Thanks. Mike Tag: Where can I get SMBClass.sys? Tag: 71995

    - Virtual adapter, change IP address through registry, enable/disable? Greetings. I have a virtual adapter based on the NetVMini sample from the XP DDK. I have been using it (successfully) for tunneling, using IpHlpApi calls to add/delete IP addresses. However, this implies that the adapter has a dummy first address (DHCP off, so it usually sits there as 0.0.0.0). I would like to be able to change the primary address on the adapter instead of adding a second one when needed. I have seen some virtual adapters who do this exact thing and I'm wondering what steps are involved. I know that the following works: - disable virtual adapter in device manager - make registry changes in HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{.......} - enable virtual adapter in device manager This is rather slow, however, and I was hoping a similar effect could be obtained by using Windows' media sensing mechanism. I thus tried the following: - internally set my connection status to "disconnected" (this is what my virtual adapter responds to an OID_GEN_MEDIA_CONNECT_STATUS query) - indicate NDIS_STATUS_MEDIA_DISCONNECTED with NdisMIndicateStatus - make registry changes, as above - internally set my connection status to "connected" - indicate NDIS_STATUS_MEDIA_CONNECTED with NdisMIndicateStatus Sadly, although this is way faster than the first option, the new IP information does not seem to get fetched from the registry. I did some OID debugging and saw that the only OID_GEN_MEDIA_CONNECT_STATUS (0x00010114) request my adapter received was when I ran IPCONFIG (which queries the adapters directly). Furthermore, my calls to NdisMIndicateStatus do not have much of an impact on the way Windows behaves with the adapter (GetIfEntry's dwOperStatus goes from "Operational" to "Non Operational"). Any ideas? ----- Benoît Bousquet Tag: Where can I get SMBClass.sys? Tag: 71989
