    - Problem reconfiguring PCI-e device in Vista Hi, I'm writing a driver for a proprietary PCI-e adapter. The board contains multiple FPGA-based PCI-e devices behind a PCI-e bridge. From time to time, we need to reconfigure the FPGA's while the system is alive. We do not however want the system to reboot (think of it as hot- swapping without physically replacing the device). The problem is that the FPGA's incorporate the PCI-e interface so that they cannot be reconfigured while they are active. In XP we finally managed to reconfigure the FPGA's by first calling CM_Query_And_Remove_SubTree() on the bridge (being the parent devices of our FPGA's). This causes the FPGA-devices to be switched to the D3- state, after which they can safely be reprogrammed. We then call CM_Reenumerate_DevNode() on the parent of the bridge device so that the new FPGA-devices are recognised again. In Vista however, the system seems to automatically re-enumerate the PCI bus immediately after the CM_Query_And_Remove_SubTree() has completed. This causes the FPGA's to be accessed while they are being configured resulting in a BSOD (Machine-check-excpetion). - Any idea how to disable (or delay) the re-enumeration of the PCI- bus? - Any link to more extensive documentation of the internals of the PnP system? I've found many ways to manage PnP devices, but little or no information about what is happening behind the scenes. - Any suggestions for alternative methods to achieve the reconfiguration? Note: redesigning our hardware is no option. Thanks in advance for your help, Koen Tag: Winusb.sys and winusb.lib source Tag: 102638

    - Vista 32 bit display driver for small lcd's on USB Hi I need to make a solution which permits having secondary monitors on USB (small ones - vga/qvga) As far as I seen the display driver model has changed completly from the XP. Does anybody know a good startpoint for a vista display driver? The R200Sample from the WDK is a good starting point? A second problem is that Vista does not permits having two WDDM display drivers from different vendors. Does anybody knows solutions for this? XPDM is not really an option (only last one) since it switches off aero on primary monitor too which is something would need to avoid ... regards, -- -Barni Tag: Winusb.sys and winusb.lib source Tag: 102637

    - INF file for SMBus driver Folks, I am writing a client driver for an SMBus device on a PCIe card. The SMBus device gets detected by the host controller. I can see the device listed by utilities like SpeedFan. The SMBus device uses a persistent slave address (actually an I2C device posing as an SMBus device). My question is how does one write an INF file for such an SMBus device - more specifically, how does one describe the device. I found this entry in the acpi.inf file - %SMBALI.DeviceDesc% = SMBALI_Inst,ACPI\SMBUS&VEN_10B9&DEV_7101 I guess this will work for devices that use dynamic address and get their address using ARP because the device id and vendor id will be available to the SMBus host controller from the device's UDID. But for SMBus devices that do not have things like UDID how does one specify the device description. Thanks, Ashwat Tag: Winusb.sys and winusb.lib source Tag: 102634

    - Bluetooth profile driver in vista Hi all, I have some confussed questions. Yes, I read some msdn about bluetooth profile driver development in MSDN. But unfortunately, I haven't find source code in WDK sample. There are some questions : 1) If I write a headset or handsfree profile driver, I should communiate with SPP profile or RFCOMM stack. But I can not find the programming interface. 2) What interface should profile driver provide? For handsfree or headset profile, it should cowork with windows audio stack in bluetooth vista stack. But how? And the last question, do we need develope alll profile driver for user? or Microsoft will provide all profile driver in vista? Tag: Winusb.sys and winusb.lib source Tag: 102631

    - Network bridge interface configuration I am trying to configure a network bridge programmatically. I can create and remove one fine using devcon, but how can I add my interface adapters to the existing bridge programmatically? Can I use devcon, or must I do some DLL calls through hnetcfg.dll? If I have to go the latter route, how do I get the function signatures (and any associated info I might need, if they take complex structures as arguments)? I know netsh does a lot, but there isn't much/any bridge configuration capability with it. Thanks in advance, -- Kevin Tag: Winusb.sys and winusb.lib source Tag: 102619

    - DDK Halftone Functions Hi, I notice that print drivers, through the DDK, have access to some pretty neat halftone functions, with various halftone patters like these... HT_PATSIZE_2x2 HT_PATSIZE_2x2_M HT_PATSIZE_4x4 HT_PATSIZE_4x4_M HT_PATSIZE_6x6 HT_PATSIZE_6x6_M HT_PATSIZE_8x8 HT_PATSIZE_8x8_M HT_PATSIZE_10x10 HT_PATSIZE_10x10_M HT_PATSIZE_12x12 HT_PATSIZE_12x12_M HT_PATSIZE_14x14 HT_PATSIZE_14x14_M HT_PATSIZE_16x16 HT_PATSIZE_16x16_M HT_PATSIZE_SUPERCELL HT_PATSIZE_SUPERCELL_M HT_PATSIZE_AUTO Is it possible to access these same halftone patterns throguh the regular Win32 API or SDK? I am not writing a driver, but I am trying to add halftone capabilities to an old legacy C Win32 application, and I thought there might be a way to leverage these pre existing microsoft halftone functions in the app. Is it possible to get these same patterns through BitBlt, or StretchBlt, etc?

    - question about 64-bit compliant DDK samples I am playing around with the samples in the DDK. In the HTML document, it says "this is 64-bit compliant". Does this mean that it won't run on my 32-bit Windows XP system? I tried to install 64-bit compliant Msplotter sample on my machine. I could not see it after a successful installation. On the other hand, a 32-bit complaint software can run on 64-bit system. Am I right? I am wondering which option I should change so that I will build a 32-bit compliant samples so that they can run on my XP. Thanks in advance! Tag: Winusb.sys and winusb.lib source Tag: 102615

    - SET_LINE_CODING and usbser.sys I'm trying to write a USB to serial device (and who isn't<g>?) Right now I'm using usbser.sys. I've read all the warnings but a custom driver is currently out of the question. I don't understand why I'm not getting SET_LINE_CODING messages. When I go into Device Manager and change the baud rate, I would think that would be the time to call into usbser.sys and pass on a SET_LINE_CODING. My ultimate goal is to have the converter get the baud rate, etc on startup from Windows. Tag: Winusb.sys and winusb.lib source Tag: 102613

    - Validating parameters for IoDeviceControl in KMDF -> KMDF verifier error When testing my driver to be crash safe for various user input, I came across an issue in my driver that I don't know how to handle. To eliminate my own driver, I tested the same thing with the original WDK (WDK 6000) sample osrusbfx2 driver. By modifying the testapp to send erronous input to the driver, I could get the error/break even there. The sample uses the parameters\wdf\DbgBreakOnError = 1. Now I wonder how it should be handled by the driver, as the KMDF says it's an error. How to reproduce: To have some common code to look at, I use the sample KMDF osrusbfx2. Modify the testapp to call the driver with IOCTL_OSRUSBFX2_GET_7_SEGMENT_DISPLAY and put erronous parameters in the call: if (!DeviceIoControl(deviceHandle, IOCTL_OSRUSBFX2_GET_7_SEGMENT_DISPLAY, &sevenSegment, // Ptr to InBuffer, NULL in example sizeof(UCHAR), // Length of InBuffer, 0 in example &sevenSegment, // Ptr to OutBuffer 0, // Length of OutBuffer &index, // BytesReturned 0)) { // Ptr to Overlapped structure I've only seen it when input buffer pointer and length is valid and the output buffer pointer is correct but oputput buffer length is zero. By turning on Parameters\Wdf\DbgBreakOnError, I get: >KMDF detected potentially invalid operation by canusb.sys. Turn on >framework verifier to break into the debugger. Turning on the verifier gives me >410: FxRequest::CompleteInternal - Caller of this WDFREQUEST 7A104170, Irp >0x862BB398 is passing an OuputBuffer address even though the >OutputBufferLength is zero <yes, there is a spell error in the log: OuputBuffer> So, here's my question: if this is a driver error, how can it be corrected? If this is just invalid parameters, why does the KMDF verifier break to the debugger? Regards, Carl-Magnus Segerlund Tag: Winusb.sys and winusb.lib source Tag: 102601

    - Got few questions/doubts about MDL (after browsing archives/web) on this subject Hi, Working on a problem at hand with miniport network driver. I have few questions related to MDL & NET_BUFFER. My questions are: 1. What is the maximum size of virtual address-range that a single MDL can map? (I am under the impression that only one page of contiguous virtual address range can be mapped by a **Single** MDL. Let me know if this is wrong). 2. If a single buffer whose virtual address range is more than 8 K (size of receive buffer is more than 2 page assuming 4K page size), how many MDLs would be required in the *LEAST* to map the entire virtual address range? Answer to Q#1 will probably answer Q#2 as well. If not pls include answer for this as well. 3. Can ByteOffset be more than size of one physical page? I see that ByteCount value of Mdl returned by NdisAllocateMdl (length = 9k) set to 9K. 4. I have got a buffer whose size is more than 8K and I use NdisAllocateMdl to allocate Mdl to map this buffer passing start address of this buffer and complete length of this buffer. But I receive a single MDL in response to this operation? Does that not mean its mapping only part of buffer I passed? When I tried changing virtual address from (start address) to (start address + 5k), Mdl->StartVa & Mdl->ByteOffset changes to reflect next page which seems to answer my aobve question that it maps only part of the buffer. But still want to get it verified from experts on this list. How to get MDL chain mapping for the complete virtual address range and not just the first page of the receive buffer? Should I explicitly call NdisAllocateMdl() in loop for entire range starting from the start-address stepping through at size of 4k? 5. If I call NdisAllocateMdl on a buffer with address say X. I receive an Mdl and after executing some code, I realize that I need to indicate data to NDIS starting from X+5K. Can I pass the above allocated Mdl & NET_BUFFER to do this by manipulating DataOffset/ByteOffset? Thanks, -Praveen I see the following information in OSRonline doc on MDL: // Notice that while in the context of the subject // thread, the base virtual address of a buffer mapped // by an MDL may be referenced using the following: // // Mdl->StartVa | Mdl->ByteOffset typedef struct _MDL { struct _MDL *Next; CSHORT Size; CSHORT MdlFlags; struct _EPROCESS *Process; PVOID MappedSystemVa; PVOID StartVa; ULONG ByteCount; ULONG ByteOffset; } MDL, *PMDL; Also you know that StartVa is the page aligned virtual address of the start of the range and ByteOffset is the starting offset into the first page. TRIVIA POINT: MmBuildMdlForNonPagedPool sets the MappedSystemVa of the MDL to (Mdl->StartVa | Mdl->ByteOffset) and then sets the MDL_SOURCE_IS_ NONPAGED_POOL bit in the MdlFlags.

    - Synchronising read and write ops All, I am writing a very basic on the fly encryption file system filter driver as a learning exercise. I was planning on: 1. Storing the real length of the file and other information in a header 2. Reading and writing the header as part of non-cached and paging IRP_MJ_READ and IRP_MJ_WRITE operations. 3. Returning the length from the header for IRP_MJ_QUERY_INFORMATION Irps. I was planning to use a driver managed queue of Irps so that I could ensure the I could update the header in response to a write before a another thread read the header; classic synchronization problem. However, I discovered that most (if not all) of the operations use Irp->UserBuffer, and in my driver dedicated thread I would have to change process context all the time to access the buffer, which strikes me as both dangerous and extremely slow. So, my question really is how would one generally synchronize this kind of thing? Could I use an ERESOURCE and have any read operations acquire shared and write operations acquire exclusively? Is it safe to enter a critical region for all read and write Irps? Many thanks in advance! Carl Tag: Winusb.sys and winusb.lib source Tag: 102570

    - DiskId32 has trouble reading some SATA drives My DiskId32 tool, http://www.winsim.com/diskid32/diskid32.html , reads hard drive information directly from the hard drive in Windows Vista, XP, Win2K, Win9X, etc. DiskId32 works in three modes: direct using administrator rights, indirect using the scsi bypass and direct using user mode rights. The scsi bypass was dropped in Windows server 2003 and Vista. Please note that the source code for DiskId32 is there also. For some reason, the direct reading of the hard drive using user mode rights is failing for some SATA hard drives. However, the direct reading of the hard drive works fine in administrator mode. Specifically, what is failing is the reading of the serial number of the hard drive. The identify bank being returned by the hard drive is only 121 bytes long and the serial number pointer is at position 120 which has a zero in it. I would appreciate any insights or thoughts people might have for this issue. Thanks, Lynn Tag: Winusb.sys and winusb.lib source Tag: 102562

    - Storport driver dropping HBA API events? Hi, I have taken the TempConsumer SDK example and converted it to consume the MSFC_AdapterEvent class. I have a Fibre Channel driver that fires multiple events (using ScsiPortFireWmiAdapterEvent) in rapid succession. However, the consumer only sees the first event. If the events are fired a few seconds later, again I only see the first event. Is there a limitation for firing events? If so, how is an event like this one supposed to work when there is unique data (the event type) each time the event is fired? Thanks, Scott Tag: Winusb.sys and winusb.lib source Tag: 102545

    - Mysterious change in DbgPrint functionality I just solved a problem that was baffling me. I was trying to debug a driver on Vista Home Premium (32-bit) and, following advice I found online, I disabled User Account Control (UAC). All of a sudden, DebugView stopped showing messages from my driver. Turning UAC back on didn't fix it. I eventually solved my problem by creating a REG_DWORD value named DEFAULT, value -1, in HKLM\System\CurrentControlSet\Control\Session Manager\Debug Print Filter. My assumption is that disabling UAC deletes that key and re-enabling UAC doesn't put it back. -- Walter Oney, Consulting and Training http://www.oneysoft.com Tag: Winusb.sys and winusb.lib source Tag: 102541

    - CreateFile not working in vista-32 Application is calling CreateFile("\\\\.\\xxxx", GENERIC_READ | GENERIC_WRITE, etc.). Works great on Vista Ultimate (64-bit) and all pre-Vista 32-bit systems.

Device object is created with call to IoCreateDeviceSecure specifying a valid setup GUID and SDDL_DEVOBJ_SYS_ALL_ADM_ALL. Objdir shows that there is no DACL on the device object, which presumably explains why CreateFile is failing.

    - Disable driver signature enforcement in vista x64 business edition I am working on pci driver development for visa x64OS, i wanted to test my driver, whether the driver is working correctly or not. I installed my driver as i did in xp-32, 64 bit driver loaded correctly but, driver is not running, it is stopped(i verified with sc query name), i have choosen the option to "SERVICE_SYSTEM_START", though i tried to restart the driver using devcon, it says it is stopped & it is not running in vista x64. Since i am under development phase, driver is not signed, While installing the driver, it asked a pop up saying that driver is unsigned, i have choosen to install it. is the driver stopped instead of running, is it because of driver signing problem? I tried to disable driver signature enforcement using F8 option during system startup, but i dont see any difference, also treid with some bcdedit options, its same. currently i am looking KMCS_walkthrough.doc about, how to test sign the driver. Is this is the only way to test the driver, do i have to test sign the driver everytime, when the driver code is modified? Is this is the problem related to driver signing? while booting the system, i have choosen F8 to disable & tried some bcdedit options, still the result is same.

    - Select_Config in WinCE5.0 Hi, I'm developing a USB driver for WinCE5.0 and planning to support a device with multiple configurations. I don't see any USBD interface for Select_Config. Then I was planning to issue a vendor transfer for a select_config. However, in one of discussion forums, I found out that we should not issue a vendor request for a Select-Config. Instead it should be a Control transfer. As am writing a function (client) driver, I don't have the pipe_handle to issue a control transfer!! Then I found one more post regarding the same in another discussion forum. It highlighted the steps as below - You should be able to select any device configuration using the following CE USB functions: ClearFeature: Sends a CLEAR_FEATURE request to a USB device. GetDescriptor: Sends a GET_DESCRIPTOR request to a USB device. GetInterface: Sends a request to a USB device for information about alternate device settings. GetStatus: Sends a GET_STATUS request to a USB device. SetDescriptor: Sends a SET_DESCRIPTOR request to a USB device. SetFeature: Sends a SET_FEATURE request to a USB device. SetInterface: Sends a SET_INTERFACE request to a USB device, to change the device's settings The first step says, I should send a CLEAR_FEATURE. My question is, issue CLEAR_FEATURE to clear what? Should I send USB_REQUEST_SET_CONFIGURATION as the "wFeature" argument in the call lpClearFeature? I tried this, but I got a USB_STALL_ERROR in return!

    - Windows Vista wireless interface Medai unauthenticated Hi, I am currently testing wifi compatibility on Windows Vista. To connect our Wifi adapter to the network we use our own application and supplicant. Our driver blocks windows from changineg the driver state and we have our own OIDs to associate and authenticate. We use IPHelper to catch IP configuration. This all works fine on XP but does not work on Vista. On Vista this works great for the radio, and my wifi interface become "Enabled" in Network Connection Panel, but DHCP never succeed to give me an IP configuration. On the command line, by typing "ipconfig", I can see my wifi interface hanging in media state "Media unauthenticated". Well sometimes if the ap is WEP only it works after a long delay but if the the security is WPA or WPA2 we never get an IP address. It also seems that if I set a static IP on the interface then IpHelper never reports the static IP. Any thoughts? Thanks Tag: Winusb.sys and winusb.lib source Tag: 102516

This is the code I'm using (taken from a WDK sample): ----------------- ... status = WdfUsbTargetDeviceCreate(Device, WDF_NO_OBJECT_ATTRIBUTES, &pDeviceContext->UsbDevice); WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_SINGLE_INTERFACE(&configParams); status = WdfUsbTargetDeviceSelectConfig(pDeviceContext->UsbDevice, WDF_NO_OBJECT_ATTRIBUTES, &configParams); ----------------- Since I read somewhere that Vista is much more strict regarding devices following USB standards, I decided to "dump" all the descriptors and see if everything was correct. Here is the result: *********** DEVICE_DESCRIPTOR *********** bLength: 18 OK bDescriptorType: 1 OK bcdUSB: 100 OK bDeviceClass: 0 OK bDeviceSubClass: 0 OK bDeviceProtocol: 0 OK bMaxPacketSize0: 8 OK idVendor: 4512 OK idProduct: 1000 OK bcdDevice: 100 OK iManufacturer: 1 OK (?) iSerialNumber: 0 OK bNumConfigurations: 1 OK *********** CONFIGURATION_DESCRIPTOR *********** bLength: 9 OK bDescriptorType: 2 OK wTotalLength: 19 OK bNumInterfaces: 1 OK bConfigurationValue: 1 OK iConfiguration: 4 OK (?) bmAttributes: A0 OK MaxPower: 10 OK *********** INTERFACE_DESCRIPTOR *********** bLength: 9 OK bDescriptorType: 4 OK bInterfaceNumber: 0 OK bAlternateSetting: 0 OK bNumEndpoints: 1 OK bInterfaceClass: 0 INVALID bInterfaceSubClass: 0 INVALID bInterfaceProtocol: 0 INVALID iInterface: 5 OK (?) *********** ENDPOINT_DESCRIPTOR *********** bLength: 7 OK bDescriptorType: 5 OK bEndpointAddress: 81 OK bmAttributes: 3 OK wMaxPacketSize: 15 OK (?) bInterval: 2 OK (?) - The values marked as "OK" follow the USB specification - The values marked as "OK (?)" should follow the USB specification, but I don't know if Vista is happy with them - The values marked as "INVALID" do NOT follow the USB specification Do you have any idea why selecting the descriptor doesn't work on Vista, while it works flawless on XP? Are those values really ok, or is there something wrong? Is my code fine, or is the device the problem? Thanks, - AS Tag: Winusb.sys and winusb.lib source Tag: 102504

    - Printer driver GDI punting problem I am writing my first printer driver, based on the DDK sample. It is a user-mode driver for a monochrome printer. I want to hook the GDI DrvXxx graphics calls (DrvBitBlt, DrvStrokePath etc.), punt back to GDI to perform the drawing operation, and then access the resulting bitmap so that I can transmit the relevant portion of it to the printer. In DrvEnableSurface I create an engine-managed surface to use when punting back to GDI, and a device-managed surface so that I can hook the DrvXxx drawing functions :- HSURF DrvEnableSurface( DHPDEV dhpdev ) { PPDEV pPDev = (PPDEV) dhpdev; SIZEL SurfaceSize; LONG lWidth; SurfaceSize.cx = 808; SurfaceSize.cy = 592; lWidth = 101; // create bitmap... pPDev->pbBitmap = HeapAlloc( GetProcessHeap(), HEAP_ZERO_MEMORY, (SIZE_T) ( 808 * 592 ) ); // create engine-managed surface using our bitmap... if ( ! ( pPDev->hsurfEng = (HSURF) EngCreateBitmap( SurfaceSize, lWidth, BMF_1BPP, BMF_TOPDOWN, pPDev->pbBitmap ) ) ) { return NULL; } // create device-managed surface so that we can hook the DrvXxx drawing functions... if ( ! ( pPDev->hsurfDev = (HSURF) EngCreateDeviceSurface( (DHSURF) pPDev, SurfaceSize, BMF_1BPP ) ) ) { EngDeleteSurface( pPDev->hsurfEng ); return NULL; } // associate device-managed surface with GDI engine's hpdev... if ( ! EngAssociateSurface( pPDev->hsurfDev, (HDEV) pPDev->hpdev, HOOK_BITBLT | HOOK_STRETCHBLT | HOOK_COPYBITS | HOOK_STROKEPATH | HOOK_FILLPATH | HOOK_STROKEANDFILLPATH | HOOK_TEXTOUT ) ) { EngDeleteSurface( pPDev->hsurfEng ); EngDeleteSurface( pPDev->hsurfDev ); return NULL; } return pPDev->hsurfDev; } And then in the DrvXxx drawing routines I punt back using the engine-managed surface. For example, in DrvTextOut :- BOOL DrvTextOut( SURFOBJ *pso, STROBJ *pstro, FONTOBJ *pfo, CLIPOBJ *pco, RECTL *prclExtra, RECTL *prclOpaque, BRUSHOBJ *pboFore, BRUSHOBJ *pboOpaque, POINTL *pptlBrushOrg, MIX mix ) { BOOL bResult; SURFOBJ *pSurfObj; PPDEV pPDev = (PPDEV) pso->dhpdev; // obtain a SURFOBJ for our engine-managed surface... pSurfObj = EngLockSurface( pPDev->hsurfEng ); // punt back to GDI using our engine-managed surface... bResult = EngTextOut( pSurfObj, pstro, pfo, pco, prclExtra, prclOpaque, pboFore, pboOpaque, pptlBrushOrg, mix ); EngUnlockSurface( pSurfObj ); return bResult; } The problem that I have is that although EngTextOut returns TRUE, nothing is drawn onto the bitmap. This is true for all the DrvXxx drawing functions that I hook. Can anybody tell me why this should be so? Tag: Winusb.sys and winusb.lib source Tag: 102485

    - trouble installing debug bootloader for debugging boot drivers Hi, This with WinDBG 6.8.0004.0 and WDK 6001.17051, target is Server 2003 sp2. I'm attempting to follow the instructions in the WinDBG help in "Mapping Driver Files" for replacing boot drivers with the image replacement feature (kdfiles). The directions are a little thin, but I'm trying to do the gist of what they're saying by copying WinDDK's debug\i386\ntkrpamp.exe over \windows\system32\ntkrnlmp.exe. I've also tried also copying \debug\i386\halmacpi.dll over \windows\system32\HAL.DLL. This results in a message: Windows could not start because of an error in the software. load needed DLLs for kernel. What am I doing wrong? Can I use the 6001 debug bootloader on Server 2003? (Additional wrinkles: Target is running in SMP PAE mode under Xen -- debugging non-boot drivers works fine.) Thanks -- Regards -- Andy Tag: Winusb.sys and winusb.lib source Tag: 102471

    - OID_802_3_MULTICAST_LIST issued by multiple protocols Hi, What happens if two protocol drivers set their own multicast address list with OID_802_3_MULTICAST_LIST? Is it Miniport's responsibility to OR those two list, create a global list and send to the adapter or NDIS will take care of creating a global list of multicast address and send to Miniport via OID_802_3_MULTICAST_LIST? Also who will route the RX frames filtered via global multicast address list to the respective protocol drivers? Thanks, Aniketa Tag: Winusb.sys and winusb.lib source Tag: 102470

    - Video data to the USB -- from the Noob again I'm not even sure how to ask this question, but I'll give it a shot. The standard disclaimer about my cluelessness applies. I'm supposed to find out how we present our post-DSP MPEG-4 streaming data to the USB. In other words, what is the data supposed to look like so the USB likes it? Am I supposed to be looking at MPEG-4 specs of some kind, and MPEG-2 transport stream specs? How do the drivers figure into all this? Is there a book or online tutorial of some kind that talks about this stuff in English instead of technical-ese?

    - Video Driver Stack question from the Noob Again, please keep in mind my complete lack of training and experience with drivers, video, and the DDK, not to mention etc. We're building a handheld device, a PC running Vista. We're designing a camera to stream MPEG-4 video through a Blackfin DSP and over the USB. I'm looking at the Layered Driver Architecture diagram in the DDK documentation. It says "few (if any) driver stacks contain all these types of drivers", so naturally I'm wondering which ones ours will include. More specifically, which ones will we have to write? It sounds like most are supplied by Microsoft, with the exception of the user-mode client driver (which it says input devices don't typically have?), and the miniclass and miniport drivers, which are provided by vendors. Since we're just getting the camera modules from ST and doing the rest ourselves, will we be required to write the minis?

    - Direct disk device access based upon size etc... Hi, I have two storage devices (say A & B) in my system. I want to divert the traffic to one of them based upon the sizes. Say all requests smaller than 4KB goes to device A while all other goes to device B. How can I achieve that? I was thinking of putting a filter driver somewhere in the stack? But I'm not sure which is the most appropriate place. I may have some other criteria also for diverting the traffic like "OS data vs User data" etc. Also can this be done without a filter driver or any other driver like for example writing some kind of windows service? If "yes" can you point me to some documentation about windows services. Thanks in anticipation. Tag: Winusb.sys and winusb.lib source Tag: 102453

    - modifying outgoing/incoming packets in ndis 6.0 I am working on IM driver. I want to modify the src mac address of outgoing packet. I am doing this as 1. create a new mdl for ethernet header 2. create a one more mdl for the rest of data 3. modify the data in the 1st mdl 4. adjust the mdl linkage in netbuffer and send it out on packet completion , put the original mdls back in the packet But I found that while running ndistests , protocol driver does not receive the packet though packets look proper (thr ethereal) So what is the correct way to modify the packet (packet size remains same , only change packet data) in ndis 6.0 ? I checked MUX driver for vlan but vlan changes the packet size and mdls are inserted and deleted with advance and retreat. Is it necessary , in this case too ?

Hi ,
Is the source code of winusb.sys and winusb.lib available. It could be
needed if some optimization is to be done.
