    - Is anyone familiar with the sonydcam.sys sample? Hi, I have a 1394 camera that is IIDC (DCAM) compliant. I would like to connect this camera to a DirectShow based viewer, but the camera does not have a WDM driver. Apparently, the Windows DDK has a sample called 'sonydcam.sys', which I believe is a WDM Stream Class driver. Unfortunately, when I tried connecting the camera using the associated 'image.inf' file it did not work. Obviously, I'm new at this and would like to ask the following questions: Questions: 1. Is the sonydcam.sys file a WDM Stream Class driver for DCAM cameras? 2. If it is a WDM driver, can I modify the image.inf file in some way so that it would recognize my camera as 'Generic'? 3. To view the camera with a DirectShow app, do I need more than the sonydcam.sys file? Thanks for any help. RickL Tag: AVStream : Remote controller (IR) Tag: 63822

    - Filter Hook Driver and NAT I have written a application based on the Windows 2000 Filter Hook Driver. Basically the application was designed to run on a Windows 2000 server with two Network interfaces. It monitors traffic between the two interfaces and enforces security, performs proxy redirection, etc. When the Windows 2000 Server is configured for routing mode and both interfaces have real address subnets (in other words Network Address Translation (NAT) and Internet Connection Firewall (ICF) are not enabled), the hook correctly works and our application receives the packets (header and payload). However, when NAT or ICF is enabled (the network we are checking security on does not have real addresses) the Packet pointer (payload) passed to us is NULL. Therefore we can not look at the rest of the packet to make a determination of what we should do. See this link for the call back function description (parameter two is the one that we are not getting): http://msdn.microsoft.com/library/en-us/network/hh/network/fltrhook_cb402c5c-f5db-498b-8db6-c2994bbf7870.xml.asp Why does the behavior of the Filter Hook Driver difer betwen NAT and routing mode? I would think the behavior should be the same regardless. Tag: AVStream : Remote controller (IR) Tag: 63808

    - USB COM port as Serial port Hi All, Here is my problem. I have a USB modem which is exposing COM port with help of usbser.sys. Everything works fine with microsoft Dial up connectoid. When I am trying to use the USB COM port as normal serial port interface through serial IOCTLs it fails. I am accessing the port from my WDM driver. I am able to get the device object pointer of the port and able to dereference the same, but I am failing in configuring the port like set baudrate. Can I use this USB com port exposed in modem as normal serial port interface. Waiting for expert's comments. All your comments are welcome.

    - rundll32 printui.dll,PrintUIEntry Question I did a setup program in VB to install a printer driver using rundll32 printui.dll,PrintUIEntry for a silent installation. When trying it on a PC with Windows 2000 Professional just installed, it seems to have a problem installing. We installed a previous version of our driver and it created the folder C:\WINDOWS\system32\spool\drivers\W32X86\3 and then the setup program worked with the new driver. It seems to be unable to create the "\3" folder. It only works when that folder exist. I would like to know what is the "\3" folder and what creates it in a printer installation. -- Mario Tag: AVStream : Remote controller (IR) Tag: 63782

    - using devcon or dpinst for serial driver install I'm running a windows XP system with 2 standard serial ports. I have a proprietary driver (Mydriver.sys) that i want to install with DPInst on just one of the COM Ports. Both ComPorts however use the same Device ID ( *PNP0501), so DPInst will automatically install the driver for both COM Ports. Is there a way to install the driver for just one of the com ports? Would it be better to use devcon? Tag: AVStream : Remote controller (IR) Tag: 63779

    - Unloading driver Hy All, I've made a Pnp driver that I can load / unload in normal conditions (I can see that the module is unloaded when I disable the last device using that driver). The thing is that my driver is also a bus driver. And once the child driver has been plugged, loaded and unloaded (everything seems ok there), when the the bus driver is disabled, the device is correctly removed but the module is not unloaded (and I then have to reboot in order to update the .sys). Any hint on what could be stuck somewhere in my stack that could prevent the driver from being unloaded although both chil and bus devices are unloaded???? Many thanxes in advances, Francois.

    - Problem with the NDIS MUX IM driver (decapsulation not working) Hi, I'm using the Win2003 DDK and MUX sample, building using ddk tools. Running the driver on Win2003 machines. I'm writing a MUX IM driver based on the sample to do some form of 'tunneling'. I slap on my own ethernet header infront of the real ethernet header (with a custom eth type) when sending packets down (MiniportSendPackets). When my IM receives a packet (ProtocolReceivePacket, ProtocolReceive) with my header, I take it off and send the packet up. The problem i'm seeing is that the IM driver takes this extra header off, but the higher layer protocols seem to get this packet with the original tunneling header included. I've verified that i take the header off by stepping through my code in the debugger, and, I've verified that higher protocols get the original packet by attaching ethereal to the IM miniport. Whats interesting is that this thing worked 2 weeks ago. A couple of things could have changed, but i've tried to roll back everything to then, and i cant seem to get it to work. One thing that i noticed today is that earlier i was sure that my packets were coming in on ProtocolReceivePacket. Now i see all my packets coming in on ProtocolReceive. I'm wondering if this is a problem. I've attached my code snippet below. I'm also suspicious of this line: NDIS_SET_ORIGINAL_PACKET(MyPacket, NDIS_GET_ORIGINAL_PACKET(Packet)); Maybe someone in an upperlayer protocol is ignoring MyPacket and using the OriginalPacket instead ? Someone had posted in 2002 how they faced a similar issue - their IM was stripping of part of the packet, yet upper layer protocoles were getting the original packet. Their problem was something to do with retransmissions but it doesnt make sense here to me. Anyone seen anything like this ? I've been debugging this for 3 days now and i'm running out of ideas. Suggestions/Hints/Comments welcome. Thanks, Gaurav ------------------------------------------------------------- Heres how my code strips the header off (based off the MUX sample) called from ProtocolReceice and ProtocolReceivePacket. // // Strip off the tag header "in place": // pDst = (PVOID)((PUCHAR)pVa + TAG_HEADER_SIZE); // // Allocate a new buffer descriptor for the first // buffer in the packet. This could very well be the // only buffer in the packet. // NdisAllocateBuffer(&Status, &pNdisBuffer, pVElan->BufferPoolHandle, pDst, BufferLength - TAG_HEADER_SIZE); if (Status != NDIS_STATUS_SUCCESS) { // // Drop the packet // Status = NDIS_STATUS_RESOURCES; MUX_INCR_STATISTICS(&pVElan->RcvResourceErrors); break; } // // Prepare the new packet to be indicated up: this consists // of the buffer chain starting with the second buffer, // appended to the first buffer set up in the previous step. // MyPacket->Private.Head = NDIS_BUFFER_LINKAGE(Packet->Private.Head); // // Only one buffer in the packet // if (MyPacket->Private.Head == NULL) { OnlyOneBuffer = TRUE; } NdisChainBufferAtFront(MyPacket, pNdisBuffer); if (OnlyOneBuffer) { MyPacket->Private.Tail = MyPacket->Private.Head; } else { MyPacket->Private.Tail = Packet->Private.Tail; } ------------------------------------------------------------- Tag: AVStream : Remote controller (IR) Tag: 63741

    - pscript5 customization Ok here is my setup. My company uses pscript5 as the driver for there software printer. We use our own port monitor to show a dialog box to the user so they can save to disk in various file formats. My goal is to be able to share this printer on a server machine, and have the clients get the dialog box on there machine, instead of on the server. What I think needs to happen is I'll have to update/replace/mod the pscript5 driver so that when its shared over the network it will be installed on the new machine, and when the user printer from that new machine the driver will cause a dialog box to display on that users machine before sending anything over the network (maybe never send anything). This way a client can use the printer and save what ever there printing to disk. I've tried a few approaches to doing this but seem to hit dead ends. If some one could point me in the correct direction I can follow the path. Just for reference I've already gotted the ddk and managed to compile the oemps drivers, but cant figure out how to install them, I've also tried writting wrapper dlls for the pscript5.dll tried creating inf files for them.

    - Understanding the MSplotter Hi all, My aim is to modify the plotter.dll so that I can get a bitmap image(print to file). I have been looking around for the point from where I can extract the data in its 'raster format' and then pass it on to some buffer and then write it to a file. I am using the source code provided by DDK (\\WINDDK\2600.1106\src\print\msplot\plotter) and I think that the data maybe available at the file 'output.c' b'coz this is from where the data passes on to the spooler after rendering(but i would like to capture it before the rendering process). Could anybody guide me as to where I can extract the data in its RAW or raster format so that I may copy this to a file? do i need to look at other files like htbmp1.c etc.?

    - USB Over IP Hi, I have some requirement like... attach a USB-device (i.e. USB-printer, USB-Scanner and other USB-devices etc... ) to a remote computer on LAN network. And through some application network software be able to see this USB-printer, USB-Scanner as it was plugged directly into my own computer and use it. So this is more like a redirector driver. I have taken some idea of Doron Holan [MS] from this news group & thinking to write my own Bus Driver & instead of sending URB traffic to local usb controller, I'll encapusalte the URB into network packet and send it over the network. The other side (the remote one), takes the packet and then sends it to the controller on the remote host. Here are my queries: 1) Apart from the URB's, how to handle the some of the USBDLib function calls like USBD_CalculateUsbBandwidth, USBD_RegisterHcFilter, etc. These calls are direct function calls. They are not URB's. They are direct calls. They wont come to the virtual Bus driver. How to handle these kinds of request? Any Help?? 2) Comming to the server side.... At the remote side how should I proceed? What are the characteristics of this "remoting" driver? How do I design the driver which will take these URB's come from remote side and communicate with the device? Do I have to write a filter driver for usbhub.sys (USB Hub or Bus driver)? 3) How about supporting a USB-Isochronous device? Will there be any issues? Any one is working on similar kind of thing? Any ideas? Any help? Thanks Tag: AVStream : Remote controller (IR) Tag: 63648

    - Display Mirror Driver disables DirectDraw Overlays, DVD playback Hi, I'm having the same problem that was referenced about a year ago in this thread: http://groups-beta.google.com/group/microsoft.public.development.device.drivers/browse_thread/thread/51715b3805247298/6b3237452b8466b1?q=%22mirror+driver%22+overlay&rnum=1#6b3237452b8466b1 However, the above thread ends without a confirmed resolution of the issue. Curious if there is any more information available. I have tried all the same tests described in that thread. I am also targeting DX7, but if it would resolve the issue could target DX8. Specifically, I have written a simple mirror driver based on the mirror sample that is able to capture the coordinates (but not contents) of most on-screen changes. Unfortunately, when this driver is active (attached to the desktop), Windows disables DirectDraw support. This in turn, breaks DVD playback, among other things. I do not care to capture the contents of any updates (just the coordinates), but people get cranky when DVD playback is broken. Simply detaching the driver from the desktop resolves the problem, but ordinary users cannot set the necessary registry setting to turn on/off the driver as necessary. Also, this causes additional repaints of the entire desktop when Windows modifies the display devices. Another wrinkle, as mentioned in a different thread, is that if I test on a multi-monitor system with the desktop extended that the problem does not occur at all -- DirectDraw remains enabled despite the presence of the mirror driver. If I could cause this behavior on a single-monitor system, I would be all set. I am looking for any of the following solutions: 1) A setting I may use to cause Windows to keep DirectDraw enabled when my mirror driver is enabled. I would be very happy if Windows would simply overlook my driver for the purposes of DirectDraw without hampering other applications. 2) An example of a working DrvGetDirectDrawInfo for a mirror device. As described in the previous thread on this topic, I see 2 calls to DrvGetDirectDrawInfo, but no other DD calls. It would be helpful if this were in the DDK sample code. 3) Suggestions of alternate workarounds. Thanks, Andy Tag: AVStream : Remote controller (IR) Tag: 63639

    - Passing MSVAD buffer to user space Hi All, I am working with the MSVAD from the Win XP DDK. What I'd like to do is to share the buffer "m_pDataBuffer" (non-paged pool) with the user-space because I'd like to do some further processing on the captured data in user space. I have done some research and there's a few ways: 1) Use DeviceIoControl and use METHOD_IN_DIRECT or METHOD_OUT_DIRECT. 2) Mapping kernel memory to user memory. 3) Use Shared Memory Object Method (memory-mapped file backed by the paging file) In case of MSVAD, I just don't see how I can use method 1 because this is a "passive" driver and I see no code to handle IOCTLs. Method 2 is ok but you have to call MmMapLockedPagesSpecifyCache() from the context of the process that will be using the mapping. I am not sure that this will work for MSVAD because the app will be run after the driver is loaded and the context will be arbitrary. Method 3 is not recommended by MS because "the scope of the address is limited to the process in which the object is mapped, and it cannot be accessed in a DPC or ISR." Ref: http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q191840 I am not sure if Method 3 effects the MSVAD driver. Can anyone explain how to use this method to give user-space access? Does anyone know how else I can map "m_pDataBuffer" to user-space, with MSVAD in particular?? The stuff I have read references real device drivers and things get muddy when you are using MSVAD because it is a virtual device driver. Any help appreciated.

    - Unidrv's DrvNextBand hangs In this third pary virtual driver i'm looking at, the OEMNextBand function mades a call to Unidrv's DrvNextBand. This hangs for a long time until the printing dialog prompts about error. Only when i cancel the printing does the call returns and OEMNextBand completes. This only occurs when doing color printing. Printing the same document on black and white does not invoke OEMNextBand, but OEMStartPage instead. Can someone enlighten me on what's wrong here? Thanks!

    - HID device enumeration problems. First, I apologize if this post is out of context for this newsgroup. I am experiencing an unusual behavior when connecting multiple USB-based HID devices. The devices are data loggers, and are identical (Vendor/Device IDs) except for their serial number. I am not using custom drivers. Everything is being done through the Microsoft-supplied HID and Setup APIs. My application program uses SetupDiEnumDeviceInterfaces in conjunction with SetupDiGetDeviceInterfaceDetail to get the device details. Normally, all devices are found during the enumeration, and all devices work properly. However, if I keep the devices open for for an extended period, close the devices, and then reopen the application, occasionally one or more of the devices drop out of the enumeration. The devices remain missing until I physically disconnect and reconnect the USB cable from the device. Once reconnected, everything works again. Interestingly, all the devices show up in Device Manager, regardless of whether or not SetupDiEnumDeviceInterfaces finds the device. I should add that if only one device is present, there are no problems. Does anyone have any thoughts? Am I missing something? Tag: AVStream : Remote controller (IR) Tag: 63628

    - Sample code for performing a DMA from local memory to local memory Hello All, I'm new to the Windows programming/development world having all prior experience in the embedded world. In the embedded world I could access and setup the DMA controller, but it appears that it is not easily accessible from Win XP. Does anyone have any sample code that shows how to do a memory-to-memory DMA transfer on Win XP. Specifically I'm trying to transfer data to a remote device whose physical memory is mapped to a virtual address on my machine, so my machine thinks it is local memory. Thank you in advance. -- Gerald Chang Tag: AVStream : Remote controller (IR) Tag: 63623

    - Surprise removal reported, device disappears Windows XP is being used as an application platform for SCSI device testing. The devices do not have valid file systems. After downloading new firmware to the drive, Windows will detect the drive as being different(Inquiry data?) and issue a plugplaymanager event id 12 indicating a surprise removal. From that point it takes about 2-5 minutes or a reboot for the application to find the device again. A bus scan ignores the existing device at this ID and the associated commands which would be issued with a bus rescan to the driver do not occurr. Our application commnicates to the device via a custom class driver and a standard SCSI mini-port driver. 1: how can I make the device re-appear quickly? Bus scan for the missing devices are apparently bypassed inside the OS somewhere. Reboot is painful. 2: Or how can I prevent windows from marking it as removed. Disabling Plug and Play does not appear to help. It turns itself back on and it could have some other undesired side effects with it off. Tag: AVStream : Remote controller (IR) Tag: 63615

    - Printer driver problem in a mixed OS environment (XP and NT) Hi all, I have developed a kernel mode printer driver which works fine on NT4, Win2k and XP. There are only problems when using in mixed environment: - XP as PrintServer - NT4 as Client After 'Point and Print' installation on NT4 following errors occur: 1. In the Printer port settings on the NT4 client, the port to which the printer is connected is not visible (no port is selected). When I want to leave the port tab an error occured, that no port is selected (sounds logical ;-)). 2. Sometimes while 'Point and Print' insatallation the Spooler on the Server PC (XP) crashes. So printing is (most) impossible from NT4. Any Ideas? Thanks in advance Martin Background: - The printer driver is installed via a setup program on the server (with the AddPrinterDriver / AddPrinter calls). - The printer is connected to a 'self made' port, which writes printer output to disk - A test with an inf installed HP kernel mode driver did not have this problems (printing to the same port as my driver).

    - NDIS_PACKET Hi all, I'm trying to create unified view for data incoming into my ProtocolReceive. I try to create NDIS_PACKET from LookAheadBuffer (and others) if NDIS_PACKET cannot be obtained from underlying miniport. What I do is 1) allocate new buffer 2) copy into it HeaderBuffer and LookAheadBuffer (and rest of data using NdisTransferData) 3) set up header size (NDIS_SET_PACKET_HEADER_SIZE) and NDIS_STATUS_RESOURCES This approach seems not to be correct (ping from remote computer doesn't pass thru my IM).

Dear All,

I am developing an AVStream device driver for an MPEG2 USB box. Now I
want to implement the remote controller (IR) function. But I don't know what
kind of device drivers (HID, IrDA NDIS and etc) should I implement? Where
could I get remote controller (IR) sample driver codes? Any comments are very
appreciated.

Thanks,
Edward

I've never implemented anything like this myself, but from what I know
people usually either write a HID minidriver for that function or better yet
do it entirely in the firmware so that it is enumerated by OS as the
separate HID device served by drivers shipped in the box (that's how
MediaCenter remote control is done).
