    - USB Device Installation error? I am using USB Device 1. First time installalling the driver and the USB device works fine 2. But when I again reboot the system, system can't recognize the USB device But sometimes when I reboot, system can recognize the USB device 3. But When I feed the external power source to the USB device and reboot the system, system can recognise the USB device always 4. What is the problem, when not using external power supply Is the problem in PC or USB Device Driver 5. The above problem is only in IBM Think PAD X24 6.

    - Does bulkusb.sys support overlapped I/O? Hi all, I'm currently adapting the bulkusb.sys driver from the latest DDK (Win2K3 DDK). Does anyone know for sure whether it supports overlapped I/O or not? All they seem to say is that it's multi-threaded safe. Thanks. Tag: USB Driver Installation Problem? Tag: 45850

    - Disappearing Symbolic link and device Objects I have driver pair X and Y. Both are installed as a Demand Start sevices by a console app. Upon load, Driver X creates a link \\??\\Driver_X for user mode access and loads driver Y (using ZwLoadDriver). The symbolic link creted by drive X ( \\??\\Driver_X ) mysteriously disappears if I unload driver Y using the console app ( it calls service control manager StopService). The user mode apps fails to open X, obviously becuase it couldnt see the link. I verified the disappearence of the link with the sysinternals winobj. But I see the existance of the link with Osr's objdir!!! Is there any explnation why this happens? I am sure that neither the Device object nor symbolic link created by Driver X are explicitly deleted by Driver X( X never calls IoDeleteDevice or IoDeleteSymbolicLink in this case). This doesnt happen if I load X ( which in trun loads Y). Reboot the machine then try unload X using the same console app. I am running Windows 2000. This happens in only one machine, another 20 or so machines ok. -Sen Thanks, Sen Tag: USB Driver Installation Problem? Tag: 45844

    - video mirror driver Hi, I need to modify the mirror driver to get a simple information: whatever is the application that modify the desktop i need to know what is the region that Windows draw and/or update (RECT). I'm sure that this information is in the struct SURFOBJ of DrvBitBlt and DrvCopyBits so hooking this call I can grab such information. The question is: how can I send this information to UserMode Application? Can I use a IOCTL or a ReadFile ? Thanks, Pierluigi M. Tag: USB Driver Installation Problem? Tag: 45838

    - Interdriver communication page fault hi, i am a novice at drivers and need some help .. some days back i posted a query regarding mechanisms for interdriver communication among drivers not on the same stack. One of the mechanisms told was to build an IRP using IoBuildDeviceIoControlRequest() and send using the IoCallDriver() method. I allocated the buffers and built an IRP using the IRP_MJ_INTERNAL_DEVICE_CONTROL ioctl and sent it via IoCallDriver. I did it in the Passthru IM driver's MPSend() function. The idea is to route the incomming and outgoing packets' data to the TargetDriver for processing. I put the breakpoint on the SourceDriver's function in SoftICe. Now this scheme works fine once or twice when the function is called but after that there is a PAGE FAULT and everyting crashes. I thought i could get some advice on this forum regarding this. Can anybody help me with any suggestions regarding what i may be doing wrong ??? when i see the stack in the SOftIce the top most function in the stack is IoBuildDeviceIoControlRequest() .... ?? i am posting the code for the source driver(passthru)'s function and the corresponding handler in the target driver below int SourceDriver::ProcessPacket( ... KeInitializeEvent(&TargetWriteEvent, NotificationEvent, FALSE) SysInBuffer = ExAllocatePool(NonPagedPool, inparamsize) SysOutBuffer = ExAllocatePool(NonPagedPool, outparamsize) ....

    - Buffered or Direct I am writing a driver that will need to receive a pointer to a physical address to be used for DMA from another device (not the one controlled by my driver). I have control over the interface between the two devices. I wish to pass a small structure to the "other" device in the output buffer of an IOCTL call. One fo the fields in this structure will be used to pass a physical address. My first assumption is that physical (or "logical") addresses are safe to pass from one device to another. Should I pass the aforementioned structure to the second device using direct or bufferd IO? Performance is my main objective, since the actual data transfer between the devices will be relatively small will the buffered technique actually be more efficient Brian Tag: USB Driver Installation Problem?

    - Miniport question Ok, I have question ... when do miniport drivers get unloaded by the system and what is the mechanism for doing that? Also, how does a video miniport differ from the more general miniports? What I'm seeing is ... that the video miniport never exits. When I remove the device the miniport is still active, when I insert the device another instance of the miniport (i think) is getting loaded. How do I cause the video miniport to exit?

    - filter above serial waits for special char hello everyone, have installed an upper filter above serial and want to let it listen fo= r = a special character. this char will be send from a device to the com-port, where my filter is= = attached on. in detail: from an usermode app. a deviceIoControl - request is send to my filter.= the dispatch-routine for this ioctl-request sends a char to the com-port= = via self-made irp (IoBuildAsynchronousFsdRequest, IoSetCompletionRoutine= , = IoCallDriver)... that works fine so far. but, after that i need to listen for an answer from the connected device= , = which is a special character. after this char is identified, a next writ= e = with some buffer content has to start immediately. my first idea was to set up a workerthread right after the write, which = = sends a synchronous read request down to serial and waits. then, the = thread validates the content of the readbuffer and initiates the next = write-op. my question is, is this a realistic method? (this is my first experience= = in driver programming) and, can such a construction react fast enough, that the delay btw. = incoming answer and next write is physicaly below 6 ms ? thanks for your answers Tag: USB Driver Installation Problem?

    - VfW capture driver DLL doubts Hi, I am writing a VfW capture driver DLL(user-mode). But I am facing some problems in giving the data back to the client from the driver. I am using client as WME. I have followed the steps given in the NT4.0 DDK also the sample. The driver loading, opening, closing, adding buffer's are happening properly. The client is adding a new buffer after filling and giving old buffer(which it has given before) back to the client by doing a callback from the DLL. I am setting the dwFlag header as lpVideoHdr->dwFlags |= VHDR_DONE; Actually the driver should convert the H.261 data to uncompressed video samples. But in order to ensure that driver is giving data properly to the client, I want to give some static image. I am filling the lpData member like the following. memset(lpVideoHdr->lpData, (UCHAR)255, lpVideoHdr->dwBufferLength); lpVideoHdr->dwBytesUsed = lpVideoHdr->dwBufferLength; And by using DriverCallback function I am giving the buffer to client. But client is displaying the data as "black" always. When I click encoding it is creating a new file but without any data. I am very much new to video programming. I am doing something wrong. Please anybody can advice/help to correct me. I have only done audio related applications which all are standard exe's. Also is there anyway, I can use DirectX / VCM functions to convert H.261 video data to RGB/YUV format? or Do I have to go for some open source code? It would really help me if anybody can advice or give me some hints for the above. Thanks, Sreeram. Tag: USB Driver Installation Problem? Tag: 45721

    - Problem with Microsoft Bluetooth and socket accept Hi all I have successfully developed an application with the MS API. Now I want to develop a server app so I´ve basically used a complete test project found at http://www.lenholgate.com/archives/000206.html. My problem is that the application hangs on accept. I try to connect to the server from an authenticated device (Sony Ericsson Phone) and the Phone finds the computer but no services (there should be an obex service) and it is not possible to connect. I have tried both the MS and TDK dongles and both work fine from within Windows and with socket connect but not with this accept approach. Code segment: SOCKADDR_BTH address; address.addressFamily = AF_BTH; address.btAddr = 0; address.serviceClassId = GUID_NULL; address.port = BT_PORT_ANY; sockaddr *pAddr = (sockaddr*)&address; if (0 != bind(s, pAddr, sizeof(SOCKADDR_BTH))) { printf("%s\n", GetLastErrorMessage(GetLastError())); } int size = sizeof(SOCKADDR_BTH); if (0 != getsockname(s, pAddr, &size)) { printf("%s\n", GetLastErrorMessage(GetLastError())); } if (0 != listen(s, 10)) { printf("%s\n", GetLastErrorMessage(GetLastError())); } WSAQUERYSET service; memset(&service, 0, sizeof(service)); service.dwSize = sizeof(service); service.lpszServiceInstanceName = "My Service"; service.lpszComment = "My comment"; GUID serviceID = OBEXFileTransferServiceClass_UUID; service.lpServiceClassId = &serviceID; service.dwNumberOfCsAddrs = 1; service.dwNameSpace = NS_BTH; CSADDR_INFO csAddr; memset(&csAddr, 0, sizeof(csAddr)); csAddr.LocalAddr.iSockaddrLength = sizeof(SOCKADDR_BTH); csAddr.LocalAddr.lpSockaddr = pAddr; csAddr.iSocketType = SOCK_STREAM; csAddr.iProtocol = BTHPROTO_RFCOMM; service.lpcsaBuffer = &csAddr; if (0 != WSASetService(&service, RNRSERVICE_REGISTER, 0)) { printf("%s\n", GetLastErrorMessage(GetLastError())); } SOCKET s1 = accept(s, 0, 0); //I´m stuck here unsigned char buffer[2000]; memset(buffer, 0, sizeof(buffer)); int r = recv(s1,(char*)buffer, sizeof(buffer), 0); printf("%s\n", DumpData(buffer, r, 40).c_str()); HandlePacket(s1, r, buffer); memset(buffer, 0, sizeof(buffer)); r = recv(s1,(char*)buffer, sizeof(buffer), 0); printf("%s\n", DumpData(buffer, r, 40).c_str()); closesocket(s1); if (0 != WSASetService(&service, RNRSERVICE_DELETE, 0)) { printf("%s\n", GetLastErrorMessage(GetLastError())); } closesocket(s); WSACleanup(); } Tag: USB Driver Installation Problem?

    - Common Buffer based Bus Master DMA. Hi I am working on a WMD driver for a device that supports BUS master DMA but not scatter gather. I am trying to use a common buffer for DMA transfer. I am using a buffer of about 250 Kbyte, and never seem to have problems allocating it. I'm a bit concerned about map registers. The DDK docs say: "The requested size for the buffer, shown in Figure 3.12 as LengthForBuffer, determines how many map registers must be used to provide a virtual-to-logical mapping for the common buffer. At most, the number of map registers can be the value of (BYTES_TO_PAGES (LengthForBuffer)). This value cannot be greater than the NumberOfMapRegisters returned by IoGetDmaAdapter. For more information about system-supplied macros, such as BYTES_TO_PAGES, that drivers can use, see the Kernel-Mode Driver Reference." On my machine IoGetDmaAdapter returns 2. Does this mean that I can only transfer up to 2 pages of memory at one go (ie 2*4K on my machine). Unfortunately neither the DDK or the Walter Oney book seem to cover this topic well. At the moment I just ignore the number of map registers and assume it will be OK. Half way through the PCI board transferring data from its self to the PCI address returned by AllocateCommonBuffer it bug checks. Is this likely to be because it ran out of MapRegisters? If so how can I go about transferring larger amounts of data under the control of the PCI card (or the DSP on it). I currently have a synchronisation scheme between the PC and the DSP using PIO (which sets up and controls the DMA) and I do not want to have to change this (ie I don't want to use Packet based transfer). If it comes to It I would rather send multiple buffer locations to the DSP using PIO and program the DSP to do a "scatter gather type operation". Thanks Tag: USB Driver Installation Problem?

    - modem.sys and device path exerciser We've got a problem with our modem stack running under device path exerciser from HCT suite, under XP. Occasionally, IRPs get stuck in MODEM.SYS queue. Those IRPs are originated from DeviceIoControl, code 0x002B0018, which is some private MODEM.SYS IOCTL. Modem.sys converts those to IRP_MJ_READ or IRP_MJ_WRITE and sends further to the lower driver.

The completion routine is UniStopReceiveComplete, which got called. On the disassembly, one can see that this completion routine has the great potential to screw things up: Modem!UniStopReceiveComplete: f880f520 8b442404 mov eax,[esp+0x4] f880f524 8b4028 mov eax,[eax+0x28] f880f527 50 push eax f880f528 ff74240c push dword ptr [esp+0xc] f880f52c 05f0010000 add eax,0x1f0 f880f531 50 push eax f880f532 ff15d0f880f8 call dword ptr [Modem!_imp__KeInsertQueueDpc (f880f8d0)] f880f538 b8160000c0 mov eax,0xc0000016 f880f53d c20c00 ret 0xc Which is equivalent to: NTSTATUS UniStopReceiveComplete(<standard args>) { KeInsertQueueDpc(&DeviceObject->DeviceExtension->CompletionDpc, Irp, DeviceObject->DeviceExtension); return STATUS_MORE_PROCESSING_REQUIRED; } For the code to work correctly, modem.sys has to make sure there is always only one IRP with that completion routine active. It means, such IRPs should be serialized before they go to the lower driver. I don't know if modem.sys actually serializes them, or it just (wrongly) assumes there won't be such a case. The device path exerciser may bombard modem.sys with series of similar IRPs (for example those with 2B0018 (?) IOCTL code). If two such IRPs are sent by the exerciser and completed before CompletionDpc has a chance to run, the first IRP is lost, and I believe this is why the IRP gets stuck. It is absolutely bad idea to queue a per-driver DPC with an IRP argument, without making sure those IRPs are serialized. The driver should queue those IRPs in some list instead (using Tail.Overlay.ListEntry), and the DPC should then handle the list. Tag: USB Driver Installation Problem? Tag: 45704

    - ISA Interface Card Dear DDK experts I'm working on a Device Driver for an ISA Interface Card because we are porting Device Control software from MSDOS to Windows 98 I have Visual C++ installed and the Windows 98 DDK (Driver Developer's Kit) plus the Microsoft Press text book "Programming the Microsoft Windows Driver Model" It is a home made ISA Interface Card so there are no commercial drivers available off the shelf. The Visual C++ 6 "Windows Driver Model Wizard" creates a skeleton project. Is there sample code for making ISA Interface Card Device Drivers that I could adapt for our purpose and a "step by step" text book since I am a novice with the DDK Stephen Tag: USB Driver Installation Problem?

Dear all, I'm developing a device driver which needs semi-real time operation for Notebook PC. I want know how long my ISR can stay at DIRQL not DISPATCH_LEVEL. Is there any delay constraint to exit an ISR at DIRQL? Can my ISR affect not only system performance but also system reliability? I estimated that my ISR will take 100usec or more at 1GHz general notebook PC every 2msec. Thank you for your advice in advance. Have a nice week. //Daum Tag: USB Driver Installation Problem?

    - How can i force all the applications to use specific network interface? Hi All, I have two interface on my computer. I want specific applications to use one interface and rest to use another interface. I do not have any control over the applicaions. Can i write some driver/Module in the networking stack, which will help me force the applications to use the specified interface. second part of my question is, how does socket pick up the interface. If client do not bind the socket with any local address, how does socket pick up the local interface while using connect API, if i have more than one interface? Thanks a lot in advance.

    - im filter and ipsec I have an IM network driver that works dandy for most scenarios. When a Cisco IPSec VPN is installed, we have some issues - basically the PSched/DNE drivers pick off the traffic before we see them. On XP, I was able to install using the FilterClass of "Scheduler" in the inf file, and that installs us above the ipsec drivers. That has been working reasonably so far. But on 2K this doesn't work - no matter what I do, the DNE driver always gets installed above us and pick off (and encrypts) the traffic before we can look at it. Any suggestions? Thanks,, Warren Tag: USB Driver Installation Problem? Tag: 45678

    - deferred driver updates I have three 1394 devices with same vendorId and model. So hardwareId is same and same device driver is used for all devices. When I connect more than one device and through device manager I update the 1394 driver. **The installation doesnot give any error**. Everything works fine but it was old driver and not new driver. But the new driver is updated only after reboot or if all the devices are removed and reconnected to PC. If I update the driver with only one device connected, new driver is updated immediately. What can I do to update the driver file even if more than one device is connected. (All devices use same INF file and same driver files). I manually updated all devices(enumerated in device manager and through properties-->driver update), but still old driver is used till I remove the cables or restart the PC.

    - User Vs Kernel mode -mouse like - SendInput/CreateFile("COM1",...) Hi all, I have to do a device driver for a TouchScreen monitor and it is supposed to work like a mouse. Now I'm studing how to do WDM driver (kernel-mode, right?)....But during my job of understand the firmware protocol I did an application that get touched coordinates through COM and set the windows mouse pointer to its position. This application works like that: hCom = CreateFile( "COM1", GENERIC_READ | GENERIC_WRITE... // Open COM port for read and write ... while ( true ) { ReadFile(hCom, // read bytes from serial ... SendInput // insert mouse input (movement or click) events } ???? The question is, Could I use this application installed as a Service instead of use a WDM (or other kernel-mode) driver? What problems could arise because of this ??? 1- Will that "user-mode driver" have performance problems? 2- When the system is in low memory conditions will it have problems? 2.1 - I'm supposing this application will require less than 1Kbyte in memory for some controls variables and the COM1 file handle, I'm planning use VirtualAlloc and VirtualLock to keep it in physical memory, Does it solve the problems? 3- And what about when the system is running in low CPU contions? 4- I also have to do a USB version. All of the questions above are the same for USB? 5- I'm planing use Plug-Play and Power management functionalities. Can it be well-done using "RegisterDeviceNotification" and related funcions? The application I refer above is just a MFC console application created using Visual Studio .NET. Can I call it a User-mode device driver? Is there any framework or way to do an application so it can be called a user-mode device driver? Thanks Very Much In Advance, Edgard Lima Tag: USB Driver Installation Problem? Tag: 45665

    - Disabling keyboard initialization routine on Windows boot? Hi all, I'm very new to driver development and have recently been assigned a project so that my team would be able to send keystrokes via an external host machine and a custom PS/2 connector. However the issue I run into is that upon boot, the OS will disable the keyboard drivers and not load them. I thought the solution might be to disable the initialization routine in the keyboard driver source code that comes with WindowsDDK. I've had no success is achieving this and have come to a wall. I've been modifying kbddep.c in the pnpi8042 folder which seems to define the hardware dependencies for the keyboard. Another option may be to simply override the Windows drivers and write my own basic ones? Any help would be much appreciated, Conway Mai AMD Intern Tag: USB Driver Installation Problem? Tag: 45659

    - Creating a REAL Sidewinder Force FeedBack Pro (Gameport) Driver Hi! I was playing lately with my SW FFB joystick on XP. Everything worked well except that there was no force feedback at all! I've looked a little bit on those SW XP drivers and found that there is and there will be no support for force feedback on XP for SW gameport joystick, but only for USB version. Since trying to connect gameport joystick on a USB port is non-sense, I'm thinking of adding force feedback to current driver. I know that force feedback "messages" are sent thru Midi events (I have to figure out how exactly). So, the only thing we need is to create a filter driver between current SW drivers and directX. This driver (could be a user driver only and not a kernel driver) will only send FFB events from directX to Midi port, and sw_effct.dll may give some infos (I'll also have to look in it). So, am I (totally?) wrong? Or is it possible to create such a driver? Please help, I'll need some ;) Olivier Tag: USB Driver Installation Problem? Tag: 45657

You're not going to get any more responses by repeatedly spamming the group
with your question.
Post your question and give it a few days. Sometimes you won't get a
response for a week.

If you continue to post the same question many times you'll only end up
being shunned.

Best of luck, Chris

Your device needs more power than it can get out of the system usb port, so
feeding external power makes it work. I don't think there is anything wrong
with the driver. Try your device on an external self powered hub and see you
get the same behavior.
