    - chkinf bug: No )'s in the path so no DirectX in the path Hi, Running chkinf gives me: \Utilities\Bin\x86 was unexpected at this time. This is part of a DirectX install which adds the following to the path: C:\Program Files\Microsoft DirectX SDK (April 2007)\Utilities\Bin\x86 I'm guessing the problem is this "for" line (about line 27): for %%I in (%PATH%) do ( if exist %%~fsI\chkinf.bat ( set PLibPath=-I%%I goto runit ) The "if" may become a problem too. I worked around the problem by modifying the path variable to not have that directory in the path. I did this by: 1. Typing "echo %path%" 2. Copying the path to notepad 3. Deleting the problematic directory 4. Coping the new text for the path variable 5. typing "path=" followed by pasting the new list of directories I'm not sure, but it appears another work around is to add the chkinf directory to the beginning of the path variable. I'm not sure where to report this issue, and my quick check doesn't show any documentation on this issue. I hope this is the appropriate way to get this fixed or at least documented. If not, please advise me. Thanks, Drew Daniels Tag: ATAPort Tag: 95514

    - USB communication hangs Hello NG, I am currently testing our self-developed USB device driver. It works fine on most machines. However on a few machines it seems as if a reading operation which has been passed down the stack does not return. Meaning the completion routine is never called and therefore the IRP is never completed. As my application is performing synchronous IO-operation on the device my application hangs up and can be ended only by killing it through the task manager. I found this strange driver behaviour by implementing several debug traces in a checked version of the driver and watching that traces with debug view. Debugging the driver with WinDBG also did not bring anything new. Here a short code snippet how I pass down the IRP to the lower driver: //*************************************************************************************************************************************** pNextStack=IoGetNextIrpStackLocation(pIrp); pNextStack->MajorFunction=IRP_MJ_INTERNAL_DEVICE_CONTROL; pNextStack->Parameters.Others.Argument1=(PVOID)pUrb; pNextStack->Parameters.DeviceIoControl.IoControlCode=IOCTL_INTERNAL_USB_SUBMIT_URB; IoSetCompletionRoutine(pIrp, ReadCompletion, pReadContext, TRUE, TRUE, TRUE); IoMarkIrpPending(pIrp); ntStatus=IoCallDriver(pDeviceInfo->pNextDeviceObject, pIrp); return STATUS_PENDING; //*************************************************************************************************************************************** What can be the reason for not getting the IRP completed? Any ideas? Thanks in advance Benji Tag: ATAPort Tag: 95512

    - Disabling Devices by calling Setupapi.dll, or Converting Devcon to C# Hello group, My C# app needs to disable and re-enable devices. I did some research and found that I could do exactly what I wanted by using Devcon from the DDK. Devcon disable =net @ROOT\POSNATMP\0001 Now, the next challenge is getting this to work in my app. Devcon comes with its C++ source. I see that the function makes SetupDi* calls to the Setupapi.dll library. I am not quite sure how to do this in C#. I followed Vladimir Afanasyev articles and got a little closer. I can enumerate the devices and properties. Afanasyev mentions, in the user comments, that you can disable devices as well but does not provide sample code. This means I am much closer but still not quite able to toggle the device drivers. In sum, I am looking for the answer to one of three questions. 1) Does the .Net Framework 2 provide a way to disable/enable devices? 2) If it does not, what is the best way to convert Devcon C++ sample to a C# app? 3) Alternatively, what could I add to Vladimir Afanasyev's code to disable/enable devices? Thanks in advance, J Wolfgang Goerlich Related Links: Microsoft Article 311272, The DevCon command-line utility functions as an alternative to Device Manager http://support.microsoft.com/kb/311272 .NET - Diving into System Programming - Part 1, 2, 3 By Vladimir Afanasyev http://www.codeproject.com/cs/system/divingsysprog1.asp http://www.codeproject.com/cs/system/divingsysprog2.asp http://www.codeproject.com/cs/system/divingsysprog2.asp Tag: ATAPort Tag: 95502

    - Why is IoStatus.Information is so sensitive? In a completion routine for a (pending) IRP for writing numBytes (coming via DeviceIoControl), I am setting the IoStatus block before calling IoCompleteRequest(): irp->IoStatus.Status = STATUS_SUCCESS; irp->IoStatus.Information = numBytes; IoCompleteRequest(irp, IO_NO_INCREMENT); The strange thing is that if I set irp->IoStatus.Information to the actual numBytes that were written (several hundreds), the driver doesn't like it... Strange things happen like access violation etc. But... if I set irp->IoStatus.Information to a hard coded value of 4, all is well. Why? Isn't irp->IoStatus.Information supposed to actually relay back (to the caller of DeviceIoControl) any number desired? (in this case the number of bytes actually written, just like file I/O for example. I tried to find some documentation about the *purpose* and *intended use* of IoStatus.Information but all I could find is: "This is set to a request-dependent value. For example, on successful completion of a transfer request, this is set to the number of bytes transferred. If a transfer request is completed with another STATUS_XXX, this member is set to zero." Now... I *am* returning STATUS_SUCCESS, so what's wrong with returning a number greater than 4? Thanks, Don Tag: ATAPort Tag: 95485

    - mirror driver and service in multiple sessions Hi all, I developed a mirror driver that is able to map its framebuffer into a usermode process' context. (The usermode app does this by calling ExtEscape on the mirror driver). This is all working fine but what i really want is a seperate service .exe and be able to map a specific session's mirror driver framebuffer into that service app. Obviously the problem here is that the server .exe and the session the mirror driver is in are probably different. I was thinking about using some kind of intermediate/broker process in every session but I'd really like to avoid ending up mapping the mirror driver's framebuffer into this intermediate/broker process and then somehow send it to the service app. So in other words: i want to be able to call a particular mirror driver's DrvEscape function so that it can map the framebuffer into the calling process (my service in this case). Thanks in advance! Tag: ATAPort Tag: 95474

    - New to driver development Hi, We are developing a USB thermal printer driver. We were able to install our printer using the sample codes from the DDK but how do we issue commands when we do the actual printing? I mean how do we issue the ESC sequences that are sent to the printer? Where do we write the code for this purpose? Regards, Samir Tag: ATAPort Tag: 95470

    - Pagefile and FSCTL_QUERY_RETRIEVAL_POINTERS Is FSCTL_QUERY_RETRIEVAL_POINTERS just for the first pagefile on the boot volume or does it also work for additional pagefiles?

    - Virtual network adapter ? Hello, I'm willing to write a virtual network adapter, which won't be connected to any real hardware, but will be "driven" by a running application: packet sent to this adapter shall be read by this application, and the app sometimes send packets to the adapter which are to be dispatched on whoever read on the specified port. The problem being, I'm new to driver developpement. Thus I have a couple of questions: 1 - I've installed the latest windows DDK, is ti correct ? I've seen another framework, but it seems to be vista only out of the box, right ? 2 - I'm looking at the "netvmini" sample provided by microsoft, since it also create a virtual network adapter, again, am I correct ? I'm a little lost between all teh different NDIS drivers types. 3 - What is the best way to make my driver and the running application communicate ? Ioctl control, shared memory, ... ? And what function in the driver should I look at on msdn for receiving/sending packet ? (aka: where in the driver should I put my logic for reading packets from the application, and sending the received packet to the application). Thanks for any answer -- Lepidosteus / Vianney Devreese mail: lepidosteus at gmail dot com url: http://lepidosteus.com Tag: ATAPort Tag: 95452

    - Create a virtual network adapter ? Hello, I need to create a driver for a virtual network adapter, the prupose being to allow softwares to communicate on it asif it was a real connection, while in fact it is controlled by a running application (packets sent to it are read by this application, and the same application sometimes needs to send packets "trough" this interface to answer). I'm new to driver coding, so I have some questions: 1 - I'm using the latest Windows DDK to develop this, is it correct ? (I've seen another framework for vista drivers, but I guess it isn't backward compatible out of the box ?) 2 - to do this, I'm studying the "netvmini" sample provided by microsoft, since it creates a virtual adapter that, well, do nothing. Am I correct ? (I'm a little lost between the different kind of NDIS drivers) 3 - How to make it write and read its packet to an application ? What I would like to know is both the best way to share data between them (shared memory ? ioctl control ?), and the two "base" fonction I should look at for sending/receiving packets (I've found no how to, so all I can do is study the api for this function).

    - Oemui and Oemuni...what's the difference? Hi, I am currently working on trying to convert an oemuni image printing driver to a user-mode driver instead of a kernel-mode driver for use in Windows Vista. First question, is there any reason an oemuni driver cannot be implemented as a user-mode driver? I've found these two resources on conversion ([url]http://www.unixwiz.net/techtips/win32-pdriver-ktou.html[/url] and [url]http://msdn2.microsoft.com/en-us/library/ms801104.aspx[/url]) and have tried converting along those guidelines, but am still unable to compile my driver in user mode with the ddk. Second question, is there a major difference/what is the difference between oemuni drivers and oemui drivers? I was considering porting the oemuni driver to oemui, since oemui is already compiled under user mode, but I'm not sure if that's even possible. Again, just for reference, I am working on a print driver that saves the printed document as a sequenced image file (which has been tested in Windows XP) and am trying to port it to a user-mode driver for use in Windows Vista (since vista does not allow kernel-mode drivers). Any replies/references/etc are appreciated. Thanks for taking the time to read this thread! Nuvious P.S. I am working for a company that produces this software as a FREERWARE utility, so I am unable to post any code due to legal restrictions. Again, any help is appreciated. -- Nuvious ------------------------------------------------------------------------ Posted via http://www.codecomments.com ------------------------------------------------------------------------ Tag: ATAPort Tag: 95443

    - How to get debug prints in WinDbg from Vista I'm trying to debug my property page provider application on 32bit variant of Vista Ultimate by using WinDbg with a serial connection to try and capture the snapshots being sent by the "OutputDebugString" calls, but nothing comes out to the command window! The same application works just fine under Windows XP, Server 2003, and Windows 2000. I've inserted the "IsDebuggerPresent" and "DebugBreak" function calls only to learn that the former returns a FALSE to the local variable receiving the value when the breakpoint is hit on the latter call. What isn't clear is why the debug connection is established and control is passed to the debugger, yet "IsDebuggerPresent" returns a false and "OutputDebugString" calls are not routed through the connection? I've tried setting the "Debug Print File" as defined in http://www.osronline.com/article.cfm?article=295, but to no avail. Is there another trick to getting debug print statements out of Vista to WinDbg that I'm missing? Tag: ATAPort Tag: 95434

    - Property sheets in Printer Preferences I have a problem with a property page in the printer preferences. I am setting a handle to my current printer in the creation of the property page. Page.lParam = (long)((OEMUIPSPARAM*)(pPSUIInfo->lParamInit))->hPrinter; When I open this page I save this printer handle in case WM_INITDIALOG: // OpenPrinter hPrinter = (HANDLE)((PROPSHEETPAGE *)lParam)->lParam; VERBOSE(PRNTEXT("Printer handle [%x]\n"), hPrinter); UserData.hPrinter = hPrinter; PUserData1 = &UserData; SetLastError(0); if ((PUserData = (CBMYUSERDATA*)SetWindowLong(hDlg,GWL_USERDATA,(DWORD)PUserData1)) == 0) { dwError = GetLastError(); } Now when I get into the case case WM_NOTIFY: it works to retrieve this printer handle and work with it, but when I press a button on the dialog it goes into case WM_COMMAND: and my handle is false! What am I doing wrong here? I need the access to the printer handle to use GetPrinterData and SetPrinterData. Any help appreciated. Thanks, -- \Manfred Tag: ATAPort Tag: 95430

    - kernel memory hog There is a certain well know virus/spyware protection company, (not mcaffe, not symantec) that uses a gigantic chunk (around 78 MB ) of paged memory in the kernel and NEVER relinquishes it. If this stuff is installed on a computer, my software , which uses a substantial chunk of paged memory from time to time will simply not function. So far I've not gotten anyone's attention beyond the 1st line of technical support The unnamed company is much bigger than me, what can be done?????

    - strange things about NET_BUFFER_LIST hi everybody I write a miniport driver under Vista base on the sample rtlnwifi, and I crypt the out data. What I do like this: 1, get the NET_BUFFER from NET_BUFFER_LIST 2, get the MDL from this NET_BUFFER 3, get the data address of the MDL 4, so I copy all the data of the NET_BUFFER_LIST to a buffer use this method, and I crypt the data within the buffer(size of data not changed) 5, at last I copy the data back to NET_BUUFER_LIST, send it out through the NIC on the other PC which has Vista on it, I decrypt the data. The problem is: I share a fold, and copy some files in it, such as 123.txt or aaa.bmp, from PC1 to PC2, PC2 can get the file correctly, but the strange thing is that the files on PC1 are changed, even the fold is read only! aaa.bmp can not be recognized as BMP file, and the content of 123.txt which should be "123" also can not be recognized. It seems that when I crypt the data and copy it back to NBL, I also change the content of the file(or the content in memory, because after I reboot, the files are be OK). But I think that the NBL which my miniport get from the protocol driver should can be modified, it should not changed the content of any file or other things.

    - Does devcon.exe work at all? I am trying to use devcon.exe to ease the pain of repetitively re- installing a device driver under development for test & debug purposes. The device driver I am developing is based on MSVA (i.e. has no real hardware). When I attemp invoking it like this: devcon.exe update msvad.inf I get the error message: "devcon.exe: Invalid use of update." It seems that it also requires hwid as the second parameter? So I typed: devcon.exe hwids * but all I get is: "No matching devices found." What could be not matching in the wild card * ????????? What does devcon.exe do? Does it work at all? Or am I so sleepless and tired that I can't even get a clue how to use a simple tool like this? Thanks, Don P.S. If there is another way to re-install a driver (specified by .inf and a path to the actual location of the .sys driver file) without the annoying required mouse clicking on the update driver wizard, I would appreciate describing it here.

    - Spooler does not inform the Port Monitor about errors I have compiled the XPSDrv demo targeting Windows Vista and run it on Windows XP. It fails printing some documents causing the applicaitons to hang when some standard print ports are used. I'm writing a custom print monitor grounding on the DDK example. Both the redmon and my monitor receive a premature EndDoc -- after a single 22-byte write is made. The following error is recorded in the System Event Log: " The document Microsoft Word - XPSDrv_Config-1.doc owned by valentin failed to print on printer XPSDrv Sample Driver. Data type: RAW. Size of the spool file in bytes: 405633. Number of bytes printed: 65577. Total number of pages in the document: 11. Number of pages printed: 0. Client machine: \\MERCURY. Win32 error code returned by the print processor: 2147549183 (0x8000ffff). " The same problem is observed when using RedMon -- it starts your application and delivers only 22 first bytes to it. There is no way to inform the application about failure since the monitor is not aware of it itself. I was trying getting error flag from job status retreived via GetJob in the EndDoc of my monitor -- The status is PRINTING for normally finished jobs and is additionally SPOOLING for the troublesome jobs. But but no error observed. Furthermore, I have also noticed that XPSDrv does not notify the printqueue. I have a monitor application, which logs all the activity in a printer's queue but it is silent on the XPS sample driver regardless of whether the job is printed sucessfully or fails. But that is another story. I'm sure that 1) XPSDrv must be repaired; and 2) threads must fail fast. The latter means that you should stop a task once one of it steps (which likely is a preconditioin for the subsequent stages) fails. I see no reason to invoke further processing from the monitor when printing fails and the output is incomplete, therefore. Thanks Tag: ATAPort Tag: 95414

    - Device Setup Class Question Dear All, We're developing a scientific instrument which communicates via USB to transfer experimental procedures from the PC and stored results to the PC. Can anyone advise on what Device Setup Class this should go into? I can't see one but creating a custom setup class seems a like a big step for this one product (all the others are major groups of devices) We are using the Jungo system to do the comms, so we don't have a separate driver as such, just an inf file to tell Windows to use the Jungo driver when our instrument is connected.

    - composite device behavior of UVC device on Win98/ME/2000/XP? I found UVC device would be a multi-interface USB device. For example, interface 0 is for video control interface and interface 1 is for video stream interface. As I konw, multi-interface device will display composite device first, and then find driver for each interface. However, it seems that XP SP2 only query driver for interface 0 of UVC device after display composite device. It doesn't query driver for interface 1 of UVC device. If I plug in UVC device on WinME, it will query driver for interface 0 and 1 of UVC device after display composite device. If I plug in UVC device onWin2000, it doesn't display composite device. Why doesn't Win2000 find composite device first for UVC device? I think the behavior difference is a serious problem for developing UVC driver on these OS. For example, do I need to write different driver for each interface of UVC device on WinME? Do I need to handle multi-interface in one driver on Win2000?

    - What's the best way to develop UVC driver for Win98/ME/2000? Our device follows UVC spec. Microsoft provides standard driver usbvideo.sys for UVC device on Win XP SP2 or later I would develop the UVC driver for older OS such as Win98/ME/2000. USB Camera driver can be developed based on AVStream or USBCamd model. As I know, usbvideo.sys is a AVStream driver. AVStream driver needs new DirectX is insatalled. I am not sure whether this would be a issue for users of legacy OS. We already have developed the camera driver based on USBCAMD model for other PCam devices.

    - Debugging for beginners I have just started to learn Video Capture device development. I have built and installed the testcap sample that comes with the DDK. It have tested it using AMCap and I can see the pretty test pattern (thanks Microsoft). My next step is to understand how the driver works. To do this, I would like to step-by-step the driver through a debugger. However, I am unsure how to attach the debugger to the driver - I knew when I was working with a WIA device I had to debug the WIA service. Does WDM work similarly? Or should I be attaching to AMCap? Is it possible to debug the driver on the same machine as it is running on - or do I need two computers connected by a cable? Any guidance on the simplest approach would be much appreciated.

    - Software Publishing Certificate Certificate Authority You document KMCS_Walkthrough.doc says to purchase a â??Software Publisher Certificate from a commercial CA.â?? And â??For a list of SPC CAs, see â??Resourcesâ?? at the end of this paper.â?? There is no list of CAs in the Resources at the end of the paper. Later on your document says to go to http://www.microsoft.com/whdc/winlogo/drvsign/crosscert.mspx â??This Web page includes: â?¢ A list of Root Authority cross-certificates. â?¢ A list of CAs that provide SPCs for kernel-mode code signing.â?? But again there is no list of CAs, but I will assume that the companies in the Cross-Certificate List are included in the CA list. I then picked VeriSign to investigate purchasing a â??Software Publisher Certificateâ??. But I cannot find this certificate available from this source. Why is this so hard? Please, tell me specifically what â??certificateâ?? or whatever to purchase in order to sign kernel mode drivers. On one of the examples in the document it says, â??Issued by: VeriSign Class 3 Code Signingâ??. So I went to VeriSign but the only information I could find says that this is for object signing for Internet Explorer, etc. Why is this so hard? Does VeriSign sell what I need or do I have to look elsewhere? Where should I look and what should I buy? The only mention of Digital Signing and Microsoft talks about Microsoft Authenticode to sign .exe, .cab, .dll, and .ocx. But, I want to sign a kernel mode driver. Is this the certificate or is there some other certificate? Why is this so hard? Also is there an updated document and web page that has correct information? Tag: ATAPort Tag: 95388

    - How to share a common file in 2 different inf set? Hi, Based on the INF copyfiles directive describe in the link below, it seems that for files that is shared between 2 different inf driver sets, there is no way to ensure that the latest version of the file gets retain in the system since the COPYFLG_OVERWRITE_OLDER_ONLY flag is ignored by digitally signed sets. http://msdn2.microsoft.com/en-us/library/ms794560.aspx Does anyone knows of any way to safely share a common file between 2 different inf driver set, such that one can always ensure that the newest version of the file always gets retained by the system, no matter what the order of installation was? Or is it not possible to share a common file between 2 inf driver set that is digitally signed? Thanks KS Tag: ATAPort Tag: 95382

    - accessing physical memory mapped to a pci board I would like to view physical memory that is mapped to a pci board. (I am writing a driver for the board for a real-time OS and I would like to see what data is in the board's registers after a successful startup in Windows to help recreate that in the other OS.) I tried using a tool called WinIO to try to create a virtual address to that physical memory. It works for both read and write of some addresses, like 0x9FFF0. However, the resource the board uses is address at 0xE8100000 which I cannot pick up with the tool. I have confirmed that address in windows device manager and in the BAR0 entry in the table that the PCI board registers with windows. Is there some protection in Windows that I must circumvent to view that memory? I am running XP SP2. The board's driver is installed and the board is functioning properly in windows while I am trying to read the memory. I have 1 GB of physical RAM and a swap file of 1.5 GB. (the memory address that PCI board is at appears to be about 3.8 GB offset (0xE8100000)... I'm not sure why it is able to have an address that is beyond the sum of the physical and swap memory.) I appreciate any thoughts you have. Thanks, John Tag: ATAPort Tag: 95364

    - [WIA] Minidriver (UMDF/WDM), usbscan (32/64 bit) and certification Hello, In order to use a scanner on Windows XP/2003/Vista, we can't use an UMDF driver, can we? So, we have to start from the scanner minidriver sample "wiascanr", which is a WDM driver. Is it ok for Vista? In the WIA architecture, we have to make a minidriver (user mode) but we need an USB driver (kernel mode) for instance... Is "usbscan.sys" always correct? And for a x64-based version of Vista? Finally, in order to have a "Microsoft certification", are "wiascanr" and "usbscan" usable? Thank you very much!! Tag: ATAPort Tag: 95362

    - Job opportunities Hi everyone, My employer has opened or is about to open several positions. Four of them require skills and proficiency in Windows driver writing, especially in Network and Storage drivers. Thus there are great chances that the potential candidates are readers of this newsgroup (and a few other ones. I am cross-posting). I know this group is not made for that purpose and I apologize in advance to those of you who are not interested (sorry for the cross postings too, but the skills we are searching are quite hard to find, I want to maximize our chances to find the right future colleagues). Two positions are opened in Paris, France and two will be opened in the USA (east coast) very soon. In each location there is one Senior Engineer position and one Developer-Engineer position. Contact me in private (jobs at windowsdiskless dot com) for more details (this is a forwarded e-mail address and I will receive the e-mails sent to this address).

    - optimazation options on free build environment by default Hi all. I have a question about free build environment on WDK(version 6000). On x86 Free Build Environment, MSC_OPTIMIZATION defaults to /0xs. I understand that /Oxs implies the use of the Frame Pointer Omission (/Oy) option. but /Oy- is appointed in compile. This cause is so that it is written as the following in "i386mk.inc" . DBGFLAGS=$(DBGFLAGS) /Oy- CFLAGS=$(386_FLAGS) $(NT386FLAGS) $(STDFLAGS) $(DBGFLAGS) $(PERFFLAGS) $(USER_C_FLAGS) Why will /Oy- be set ? Will there be any important meaning in setting /Oy- ?

    - WDF DMA use Hi. I'm designing a device driver that interacts with a master PCI DSP. I have read the documentation regarding the DMA abstraction and have some questions. The way that the DMA will work is packet-based mode, and packets will be 4KByte. Packets will be allocated by a user mode process, and an MDL will be built to describe this packet. Although the packet size is equal to a page size (32 bit OS) it might be fragment to several locations on the physical memory. A scatter\gather list will hold the description of physical address per fragment. The questions are: 1. What is the size of the smallest fragment? Will it be a byte? 1a. Can I assume what will be the number of fregamnts for 4096 bytes packet (reminder - it was allocates in a user mode application)? 2. Can I set the number of fragments and size? 3. If I set the trasfer length to be 4096 bytes and my packet size is 4096 bytes will a transaction contain one transfer? 4. If the DSP interrupts when a trasfer is completed, however it interrupts in other occasions, can the driver tell the difference? Can I write some logic in the DPC (ISR of course cannot tell the difference) in order to destingwish between two "reasons" of DSP interrupt? 5. Will a 4096 bytes Thank you in advanced for your help!

    - Re: No UINumber being assigned to PCI attached MPS devices in Vista Eliyas, The UINumber is correctly reported on XP. The same computer, BIOS and adapters cards are used in both instances but with different boot drives. The system uses PCI and PCI-X buses. Should there be a difference between XP and Vista? Seems like a bug... We use the UINumber to show the physical position of Adapter cards in systems we ship out. The user can then distinguish between multiple Adapter cards installed in the same system, configure the cards, attach cables, etc.. Needless to say, we will continue to ship our product with XP until we can get everything working properly and with the same performance.

    - Question regarding COM ports I'm trying to use a call to: l = ComDBGetCurrentPortUsage( HComDB, bufBits, 256, CDB_REPORT_BITS, pMaxPortsReported ); to determine if a USB serial port device is plugged in. Before plugging in the device, the device manager reports that I have 2 COM ports and 2 printer ports. After plugging in the device it reports 3 COM ports and 2 printer ports. However, before plugging in the device, a call to ComDBGetCurrentPortUsage fills in the bit array with 05 00 00... and after the call it still returns 05 00 00... (for COM 1 and COM 3) How can I determine if the USB COM device has been plugged in and if it has, what number has been assigned to it? It returns these values even if I powered up with the device unplugged. The call to ComDBGetCurrentPortUsage is in a dll written in 'C++'. The call to the dll is from a routine written in Visual Basic. Thanks for your help -- Regards, Dean Tag: ATAPort Tag: 95315

    - WdfUsbTargetDeviceSendControlTransferSynchronously from TimerExpired function causes access violation I'm currently writing a KMDF based driver that will upon insertion of a USB device, download firmware to it and then reset the USB bus causing re-enumeration. I'm not entirely clear on the best way to implement this, my current plan is as follows: * From EvtPrepareHardware, I start a timer which causes TimerExpired to be called * In TimerExpired, I do a USB control transfer to check device state, upload a block of data and then set another timer. I thought this should be working, but I'm running into an access violation somewhere in the USB stack, and I'm not sure how to debug this further. When I call this function from EvtPrepareHardware itself, everything works fine, but calling it from TimerExpired causes the access violation. The call stack at that moment is as follows: (using KMDF 1.5) nt!DbgBreakPoint Wdf01000!imp_WdfUsbTargetDeviceSendControlTransferSynchronously+0x186 mydriver!WdfUsbTargetDeviceSendControlTransferSynchronously+0x29 mydriver!TimerExpired Now I have two questions: 1. Should I be using this design or would you suggest a different way? (the protocol requires me to sleep every now and then, and since you can't just use Sleep() I decided to go for the design as described). 2. What could be causing the access violation? Is it not allowed to call USB stack functions from TimerExpired? My TimerExpired function looks something like this: VOID TimerExpired(IN WDFTIMER Timer) { NTSTATUS status; WDFDEVICE Device; PDEVICE_CONTEXT pDeviceContext; WDF_USB_CONTROL_SETUP_PACKET thePacket; BYTE buf[16]; DWORD len, nbytes; WDF_MEMORY_DESCRIPTOR memoryDescriptor; Device = WdfTimerGetParentObject(Timer); pDeviceContext = GetDeviceContext(Device); WDF_USB_CONTROL_SETUP_PACKET_INIT_CLASS( &thePacket, BmRequestDeviceToHost, BmRequestToInterface, 0x05, 0, 0 ); pDeviceContext = GetDeviceContext(Device); WDF_MEMORY_DESCRIPTOR_INIT_BUFFER(&memoryDescriptor, (PVOID) buf, *len); status = WdfUsbTargetDeviceSendControlTransferSynchronously( pDeviceContext- >WdfUsbTargetDevice, WDF_NO_HANDLE, // Optional WDFREQUEST NULL, // PWDF_REQUEST_SEND_OPTIONS &thePacket, &memoryDescriptor, // MemoryDescriptor &nbytes); // BytesTransferred } Tag: ATAPort Tag: 95314

    - How to get the packet of KS_TVTUNER_CHANGE_INFO in Analog tuner Dr Hello: I am studying analog tuner driver. I start from DDK Sample "anlgtuner". In graphedt, it can play. When i want to change the channel, it stops work with error code "Incorrect function 0x80070001". It seems that the function to receive KS_TVTUNER_CHANGE_INFO is missed in driver from DDK doc: when the tuner switches from one channel to another, A minidriver must propagate a tuning packet from its tuner filter, through the crossbar filter, and then into the analog video input pin on its capture filter. This packet is only available in user mode until it reaches the capture filter. The minidriver receives this tuning packet as a KS_TVTUNER_CHANGE_INFO structure on the analog video input pin of the minidriverâ??s capture filter. I add AVStrMiniPinProcess callback routine in KSPIN_DISPATCH of the video input pin of the capture filter. But this routine was never hit and error still occured. So how to get the packet of KS_TVTUNER_CHANGE_INFO in Analog tuner Driver? Could somebody point me out? Thanks Max Tag: ATAPort Tag: 95304
