    - IoAllocateMdl Failure- returns NULL 30% in Vista64 but not in othe Hi, I observed that IoAllocateMdl is returning NULL around 30% of the times in Vista64 but not that much in other OS. I am allocating the MDL memory for 16MB. System is AMD 64-bit 2GB RAM and for other OS also, i tested in the same PC. Do i have modify any settings in vista64-PC to increase the success rate of IoAllocateMdl? I have read in an article, when system loads heavily & runs lack of system pages, it happens, but i tried with SystemPages 0 to not limit of the pages allocation in regedit, but the response is same.

    - PC Restart required after driver unload and before installing agai Hi, I am working on a WDF PCI device driver, driver supports PNP functionality. Problem: when driver uninstalled, i had to restart the system in xp-32 & xp-64 before driver installing again, where as this is not required in vista-32 bit pc. Driver installation: I am currently using DIFX tools DpInst for installing & uninstalling the driver. I also verified that my driver unmaps the resources before uninstalling the driver using MmUnmapIoSpace to unmap the PCI memory resources. Device doesnt support power managment capability, so driver also not supporting any power managment functionality, instead it just registers the callback & wont do anything inside. Since this problem is existing only in xp, do i have to take any extra care to avoid system restart? and also, after uninstall system doesnt prompt for restart also. Thanks, Prafulla Tag: USB packet ? Tag: 105522

    - IOCTL_VOLUME_ONLINE and IOCTL_VOLUME_OFFLINE Hello: Turning around connect and disconnect disk devices I look at IOCTL_VOLUME_ONLINE and IOCTL_VOLUME_OFFLINE functions. However I donâ??t find any examples jet. I test this (in c#): SafeFileHandle h = CreateFile(â??\\\\.\\Physicaldriver3â??, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, IntPtr.Zero, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL | FILE_FLAG_WRITE_THROUGH, new SafeFileHandle(IntPtr.Zero, true)); if (!h.IsInvalid) { long bret = 0; bool ret=DeviceIoControl(h, IOCTL_VOLUME_OFFLINE,IntPtr.Zero,0,IntPtr.Zero,0, out bret, IntPtr.Zero); â?¦ Where IOCTL_VOLUME_OFFLINE is 3, meanwhile IOCTL_VOLUME_ONLINE is 2. The GetLastWin32Error returns 50, I thing â??ERROR_NOT_SUPPORTEDâ??. The Physicaldriver3 is an USB Memory stick dervice. I know others ways for disconnect USB, but my target is to reconnect the USB without human intervention. Thanks for your time! -- Juan Segura www.sd-a.com juan@sd-a.com Tag: USB packet ? Tag: 105520

    - Generating a driver without DDK,... Hi, i have a situation here which is really true. I have a old laptop, running windows 2000 professional and there is no space left for the DDK from Microsoft. I want to write and test some (simple, monolithic) drivers, targeting 2000/XP/Vista which handle a special device over USB. So the situation is that i dont have a lot of space for ddk on my machine and i am looking for a way to write a driver, compile it into a native image and all this WITHOUT the MS DDK. Is there such a way, a minimal package of compilers, headers, not bigger than 200 MB? I already have livekd and WinDbg here, but no compiler so far and no environment. The environment should be as small as possible and the compiler should be capable of inline assembly. Is something like this available somewhere? I am not kidding, i really have no space left here on the machine. This may sound funny but this is really the situation.

    - extra WHQL warnings My app calls UpdateDriverForPlugAndPlayDevices and it works. The driver is installed, the device works, everybody is happy. Except... If more than one instance of the model in question is on the bus (it's a USB device), then I get not just one WHQL warning but at least one more. And the pattern is very weird. Let's say the user plugs in one of my devices, and my app calls UpdateDriverForPlugAndPlayDevices, and the user gets a WHQL warning, and she says continue, and everything works. Peachy, right? Now she plugs in a second device and she gets two warnings. Weird! Let's say she says continue two more times and then plugs in a third device. Now she gets three warnings, but the weirdness is just getting started. She plugs in a fourth instance of the device and she gets one warning (expected) but then she plugs in a fifth instance and gets two warnings. Remember, I get the extra warnings even if all but one instance of the device in question already has the driver. But, just to be paranoid, I made sure I was not calling UpdateDriverForPlugAndPlayDevices again due to re-entrant delivery of messages to my window. Of course, I am looking to inhibit the extra WHQL warnings. Any ideas? Pete Gontier http://www.m-audio.com/ pete (at) m-audio (dot) com Tag: USB packet ? Tag: 105510

I need to mount and dismount physical drives, like \\.\Physicaldrive0 for example, for a backup software.

    - Creating an IP option within a WFP Callout Hello everyone, I am trying to design a driver that will add an IPv4 option to every outbound IPv4 packet. I have developed a WFP callout that allows me to inspect each IP packet as flows through the network layer. At this point I'd like to clone the netbuffer, add the option header and recalculate the appropriate fields. However, I am stuck at one critical area. I need to report to the higher layers that the MTU is reduced by the size of the option header to ensure that the finished packets do not exceed the MTU. Since an outbound network layer callout can not see IP fragments, I am concerned that the packet will then be fragmented, thus invalidating the header that I applied (each option is correlated to the data in the payload). Can any of the forum gurus give me any advice? Thanks! Tag: USB packet ? Tag: 105505

    - Access violation when device plugged out I have allocated using ExAllocatePoolWithTag to allocate buffer from non paged pool for reading data through the USB AV streaming device. when the driver is streamng the data from the device, and when device is suddenly removed, I check for the URB's status for NO DEVICE after IoCall driver to the next device object. The data recieved is buffered and processed and sent to the other layer. during this time some time when the device is plugged out suddenly, it gives ACCESS VIOLATION BSOD with 0x7E, I am sure the allocated memory is not freed also, the accessed location is not out of bounds of the allocated memory area. The address is not null. Is there any way to check whether the address is valid. This happens only when the device is plugged out. and during normal operation, it works fine. There are 2 possibilities: Device present: during this time bulk transfer is done to read the data from deivce into the buffer and is further sent to processing. Device is removed: when a bulk transfer is attempted, it is programmed to return STATUS_NO_SUCH_DEVICE such that the call is returned and the buffer pointer is not sent for processing. In both the case, how does it give access violation, as the buffer is allocated and is not freed yet. Can somebody let me know if any thing I am missing.. Thanks.. Tag: USB packet ? Tag: 105495

    - Bug in usbser.sys when using a high speed hub I have a full speed USB device that I'm developing that uses usbser.sys. I found that if I connect the device directly to my Dell laptop everything works find. If I connect the device through a high speed USB 2.0 hub everything is very flaky. I see hangs when opening the com port, Windows lockups, and other wierd falures. I found a workaround. If I disabled the enhanced USB controller in device manager to force the hub to use full speed everything is rock solid. So this makes me think the problem is either a bug in Windows or a bug with the Intel chipset in my Dell Inspiron laptop. 1. Is this a known bug in usbser.sys or Windows? 2. What do I need to do to report the problem? My operating system is Vista SP1. Tag: USB packet ? Tag: 105484

    - Deserialized miniport question Hi, I am leveraging a deserialized miniport driver that hooks into the NDIS library. The driver is written in WDM format, not in WDF, and the OS is Windows XP The miniport driver hooks into the Windows TCP/IP stack and uses my hardware driver to send and receive data across the physical medium. The hardware is a PCIe Non-transparent bridge. I have successfully connected on a HARDWARE level, and am able to transfer data back and forth between the processors' exposed memory. Consider: Processor A = Windows XP = miniport Driver. Processor B = other side of the NTB PCIe chip. Processor A boots first, and establishes the connections as far as it can. When Processor B boots, it sends a GRATUITOUS ARP to Processor A through my hardware and miniport driver. 1) From what I can tell, the ARP comes across from B to A, and I can see it in Wireshark when I monitor my adapter. HOWEVER, the ARP information does not get logged into the ARP table, even when I â??preloadâ?? the table with the IP and a bogus Physical Address. I was expecting the Physical Address to get updated with the GRATUITOUS ARP, but it doesnâ??t. 2) Data from the GRATUITOUS ARP is passed up to the Windows stack via a call to NDISMIndicateReceivePacket() in my minport driver, and I can see my MiniportReturnPacket() function get called to release the packet. 3) Next, when I try to â??pingâ?? Processor B from Processor A, I can see the ping request come across into Processor B, and then see B respond back to A. I see the data come through into the miniport driver, but it all hangs when NdisMIndicateReceivePacket() is called. There is no Blue screen of Death, but it might as well, because it all hangs. It BEHAVES as if the system is locked on a spin lock, but I donâ??t think that is it. I can comment in and out the NdisMIndicateReceivePacket( ) to change behavior. The OOB data packet status is set to: NDIS_SET_PACKET_STATUS(RecvPacket, NDIS_STATUS_SUCCESS); Prior to calling NdisMIndicateReceivePacket(). I am looking for ideas on what to look into as possible suspects. Does anyone have any thoughts? Thanks, Jan Tag: USB packet ? Tag: 105480

    - USB 2.0 Streaming MPEG - Best way to queue request? We have a USB 2.0 device that outputs small multiples of MPEG2 TS packets(188 bytes), and therefore need to queue up multiple BULK requests to the USB bus driver(USBD) in order to keep the MPEG2 video flowing without dropping packets. Since in BULK mode our requests are not aligned on 512 byte boundaries, submitting a large buffer to the USBD does not help, since in BULK mode a transaction of less than 512 bytes ends the session. So the question is: What is the best way to queue up multiple BULK requests with small buffers in the driver? Are System Work Items a way to go, queue up multiple initially, then requeue in the callback? The DDK docs indicate that the System thread pool is a shared resource and should be used sparingly... Any suggestions would be appreciated. Thanks -decoder Tag: USB packet ? Tag: 105477

    - custom page size and dmPaperLength/dmPaperWidth If in Microsoft Word's "Page Setup" dialog I select custom page size and enter 1.5 inch width by 1 inch high, how does this information get passed to the printer driver? I expected that the DEVMODE passed to DrvEnablePDEV would contain the correct dmPaperLength and dmPaperWidth, but these values seem to be the default form size for the printer. I set a breakpoint at DrvEnablePDEV and inspected every DEVMODE passed to the driver. All of them contained the default page size as set in the "Printing Preferences" property pages. Several of the calls showed the DEVMODE dmFields did have DM_PAPERLENGTH and DM_PAPERWIDTH set, but the values for those fields were still the default for the printer. I know these values are available because another vendor's printer driver works correctly in this case. What am I missing? Neal Tag: USB packet ? Tag: 105452

    - BthPort - How do I get the connection? I notice that there are a series of Bluetooth functions that talk to and return a handle to BthPort. I need something like "\\?\BthPort" that I can call from another driver. Unfortunately MS made all the control calls only callable from another device driver (IRP_MJ_INTERNAL_DEVICE_CONTROL) and not from the App layer so I need to write a relay driver to call SCO. I see that BthPen, BthModem, BthEnum, and BthUSB have calls. What is the exported device name for BthPort? Thanks, -Erik Tag: USB packet ? Tag: 105442

    - Filtering the I/O requests sent by non-system applications in a file HI, I'm a newbie in the world of drivers. I'm developing a file system filter driver that needs to process all I/O requests sent in by user mode applications eg; MS Word, Excel etc; I don't want to do any sort of processing on IRPs generated on behalf of the Windows OS itself ( I'm not sure I'm using the correct words here :) ). To put it simple, I want to distinguish between IRPs generated on behalf of the OS processes and those generated on behalf of user mode applications. Could anybode tell me the easiest mechanism to achieve this? Thanks in advance, Shaji. Tag: USB packet ? Tag: 105429

    - STORAGE-0012: Separated Cache Solution WHQL test I have a question about the Separated Cache Solution WHQL test. =46rom the language contained within, it seems the STORAGE-0012 test suite is defined to be more or less a stand-alone set of requirements that is self-contained from the perspective of not having a dependency on any other STORAGE-XXXX tests except STORAGE-0005 (except if a separate flash disk device is exposed in which case the device must be logo=92d separately as well). Barring the separately-exposed device case mentioned immediately above, it appears in particular that a STORAGE-0012 =93storage adapter=94 does not imply/include a requirement to meet all STORAGE-002 (Storage host controllers and adapters) requirements For one thing, it seems that if that was the intention, it would have been explicitly mentioned as that is the convention throughout the Windows Hardware Logo Program Requirements document. if anybody could give us an opinion on the relationship or non- relationship of STORAGE-0002 to STORAGE-0012, it would be most greatly appreciated.

    - returning DCR_HALFTONE from DrvDitherColor What does it mean to return DCR_HALFTONE from my printer drivers DrvDitherColor function? The DDK states that the return value should be "DCR_HALFTONE if the engine should create a halftone approximation for the driver." I return DCR_HALFTONE but this seems to have zero effect on the use of gray or colored brushes used by applications when drawing into my printer DC. In most cases, anything that is not white is printed as black. For example, black text on a gray background prints as a black block. Also, the following is from the comments section of the DDK documentation for DrvDither Color. What the heck does this mean? "Monochrome device drivers, including most raster printers, should use the iMode parameter to tell GDI how to get good gray-scale patterns." I don't understand. The "iMode" parameter is passed to my driver. What does that statement mean "to tell the GDI" ??? Tag: USB packet ? Tag: 105415

    - PnP device recognition Hi. i have a question regarding the PnP mechanism. my driver (WDF based) controls a pci board. my system can have between one to ten boards on its backplane. my question is - is there a way for me to know (to be sure) that PnP have finished dealing with all of my boards (that are related to my driver) in a given moment. my user mode side of the system needs to know weather there are still boards that were not handled by the PnP. a possible soulution might be using some kind of configuration, meaning that the user mode will have to know how many boards exist on a given system and will be able to query the driver of how many boards were found in a given moment. but since i try to avoid this kind of solution i would to know if the OS/pnp mechanism can help me with that. thanks a ot, kobi.

    - Problem with mapping more than one page using ZwMapViewOfSection u Hello, I have a problem with sharing memory, which is bigger than one page (4 kBytes), between driver and user space application. In a driver I have allocated static global variable char myTable[sizeof(__int64)*2044]; //size of it is 16352 bytes and initialized it with simple loop: __int64* initPtr = (__int64*)myTable; for (__int64 i=0; i<size/sizeof(__int64); i++ ) intPtr[i]=i; Next Iâ??ve tried to share this table with user mode application. Iâ??ve achieved this by execution of the following code: void getSharedMemory(void* pVA) { HANDLE physicalMemorySectionHandle; UNICODE_STRING physicalMemorySectionUnicodeString; OBJECT_ATTRIBUTES physicalMemoryObjectAttributes; PVOID physicalMemorySection = NULL; PHYSICAL_ADDRESS physicalAddressBase; PHYSICAL_ADDRESS viewBase; NTSTATUS status; PVOID mappedVirtualAddress; HANDLE processHandle = ZwCurrentProcess(); if (NULL == pVA) return; /* Mapping memmory to user space */ RtlInitUnicodeString (&physicalMemorySectionUnicodeString, L"\\Device\\PhysicalMemory"); InitializeObjectAttributes (&physicalMemoryObjectAttributes, &physicalMemorySectionUnicodeString, OBJ_CASE_INSENSITIVE, (HANDLE) NULL, (PSECURITY_DESCRIPTOR) NULL); status = ZwOpenSection (&physicalMemorySectionHandle, SECTION_ALL_ACCESS, &physicalMemoryObjectAttributes); if (!NT_SUCCESS(status)) { *((PVOID*)pVA) = NULL; return; } status = ObReferenceObjectByHandle (physicalMemorySectionHandle, SECTION_MAP_READ, (POBJECT_TYPE) NULL, KernelMode, &physicalMemorySection, (POBJECT_HANDLE_INFORMATION) NULL); if (!NT_SUCCESS(status)) { *((PVOID*)pVA) = NULL; ZwClose(physicalMemorySectionHandle); return; } /* convert kernel va to real phisical address */ physicalAddressBase = MmGetPhysicalAddress(myTable); viewBase = physicalAddressBase; mappedVirtualAddress = NULL; ULONG size = sizeof(__int64)*2044; //size of global static table status = ZwMapViewOfSection (physicalMemorySectionHandle, processHandle, &mappedVirtualAddress, 0L, size, &viewBase, &size, ViewShare, 0, PAGE_READWRITE | PAGE_NOCACHE); if (!NT_SUCCESS(status)) { status = ZwMapViewOfSection (physicalMemorySectionHandle, processHandle, &mappedVirtualAddress, 0L, size, &viewBase, &size, ViewShare, 0, PAGE_READWRITE |PAGE_WRITECOMBINE); } if (!NT_SUCCESS(status)) { status = ZwMapViewOfSection (physicalMemorySectionHandle, processHandle, &mappedVirtualAddress, 0L, size, &viewBase, &size, ViewShare, 0, PAGE_READWRITE); } if (!NT_SUCCESS(status)) { *((PVOID*)pVA) = NULL; ZwClose(physicalMemorySectionHandle); return; } //now size is 20480 â?? rounded up to 4kB boundary mappedVirtualAddress = (PVOID)((ULONG)mappedVirtualAddress + (ULONG)physicalAddressBase.LowPart - (ULONG)viewBase.LowPart); *((PVOID*)pVA) = mappedVirtualAddress; ZwClose(physicalMemorySectionHandle); return; }; It looks everything works OK, but when Iâ??m trying to read whole the table from user space application the result is as follow: [Value] [Mapped Virtual Address (hex)] 0 348b58 1 348b60 2 348b68 3 348b70 4 348b78 5 348b80 6 348b88 7 348b90 8 348b98 9 348ba0 10 348ba8 11 348bb0 â?¦â?¦â?¦. 652 349fb8 653 349fc0 654 349fc8 655 349fd0 656 349fd8 657 349fe0 658 349fe8 659 349ff0 660 349ff8 14757395258967641088 34a000 <- here is next page and problems begins 14757395258967641292 34a008 1507725027235463051 34a010 5028082440786512726 34a018 17889923897613475068 34a020 23678979336568832 34a028 3640333463937649408 34a030 277895171801089 34a038 â?¦.. The problem appears not always but very often. It always lies on the boundary of two pages. Usually first or first two pages are visible properly but third, fourth and next pages are totally wrong. The table is static and allocated in driver so it is for sure NONPAGED memory. Is it a problem with Virtual Translation Table at user space side? Why, in spite of usage ZwMapViewOfSection which maps 20480, third, fourth and following pages are not visible form user application? Tag: USB packet ? Tag: 105392

There are several tools available that monitor the flow of requests into
and out of the host controller driver. If you want to watch packets after
a device is running, that's about the closest you can get.

If you need more detail, or if you need to monitor packets before a driver
loads, then you need to use a hardware bus analyzer. Those cost real
money...
