    - PICs for driver signing in x64 unavailable? I was just forwarded an email response we received from WinQual when we inquired about getting a PIC for signing our drivers for the new x64 signing policy. I'm hoping I'm just over reacting, but... I was disturbed to hear that they are not available at this time. In fact, there was a strong implication in this email that PICs would not be available until the last release candidate for Vista. Here is the relevant portion of this email: "This is not available yet, but should be in time for Vista launch. The PIC is a new signing program for files we couldn?t sign before. We?ll be making more announcements regarding the availability of PIC to sign drivers as we get closer to the Vista logo program launch, which will be at the last Release Candidate." Microsoft has done this in the past (i.e. not releasing full WHQL tests, signing tools, etc. until just before RTM), and it always has caused problems. So I'm trying to head this off at the pass this time. I don't know about the rest of you, but we need time to get a PIC, integrate signing with it into our build process, build a driver, test it internally, fix any problems that signing caused (and rebuild and retest) and deliver a candidate driver to the OEMs early enough that they have time to test it themselves (and get any needed bug fixes) before their deadline for burning a golden master for manufacturing of their first x64 machines. And that's assuming that the Vista Beta community doesn't find any bugs in the kernel embedded signing code in Windows... I'm crossposting this to m.p.d.d.d because I think this issue is of wider interest than just the winlogo newsgroup. And yes, I've already sent an email to WinQual about this. -- Ray Tag: USB Host controller on Windows Tag: 76867

    - Bug in CDROM.SYS In DDK2000...WDK 5112, CDROM.SYS!CdRomInterpretReadCapacity contains the following code: ---------------------------- // // Calculate media capacity in bytes. // commonExtension->PartitionLength.QuadPart = (LONGLONG)(lastSector + 1); // // we've defaulted to 32/64 forever. don't want to change this now... // fdoExtension->DiskGeometry.TracksPerCylinder = 0x40; fdoExtension->DiskGeometry.SectorsPerTrack = 0x20; // // Calculate number of cylinders. // fdoExtension->DiskGeometry.Cylinders.QuadPart = (LONGLONG)((lastSector + 1) / (32 * 64)); commonExtension->PartitionLength.QuadPart = (commonExtension->PartitionLength.QuadPart << fdoExtension->SectorShift); ---------------------- The code rounds the number of cylinders to (32*64) for DISK_GEOMETRY, which results in a wrong value returned to the caller. The number of sectors becomes wrong, too (TracksPerCylinder * SectorsPerTrack * Cylinders). IOCTL_DISK_GET_DRIVE_LAYOUT and IOCTL_DISK_GET_PARTITION_INFO return the correct media capacity in PARTITION_INFORMATION.PartitionLength. The difference between PARTITION_INFORMATION and DISK_GEOMETRY prevents certain filesystems, including NTFS, from being mounted from CD/DVD/BD/HDDVD/... >> // we've defaulted to 32/64 forever. don't want to change this now... I think now it's a good time to fix it at last, at least for Vista. Thanks Tag: USB Host controller on Windows Tag: 76866

    - WDF 1.0 PCIDRV.sys and NDISEDGE.sys will not load I built pcidrv.sys and ndisedge.sys with Winddk Longhorn x86 checked environment, plus set_wdf_env.cmd and kmdf\inc. Then installed them with the netdrv.inf and wdf**.dll co-installer in vista Beta2. However, both drivers cannot be loaded and the device manager error code is #37, "Windows cannot initialize the device driver for this hardware." No any event log associated with those failure either. Can any Microsoft expert duplicate the problem ? or I missed anything during build or install ?

For AMD64 assembly code, will the return values be stored in RCX & RAX registers?

    - unidrv plugins and dialog boxes I have been having difficulty trying to determine where it is possible to display a dialog box from a unidrv plug-in. From what I read in the documentation it appears as though both UI and rendering plugins run in the application's context, before anything is sent to the spooler. If this is indeed the case I would assume that it would be possible to display a dialog box to capture document specific properties during EnablePDEV processing in a rendering plug-in. This would allow me to capture things like fax #s for each document by displaying a dialog to the user who started the job. I further assume that the dialog box would appear in a particular user's termnal services window. Are my assumptions correct or am I completely out to lunch? If I am out to lunch what would be the easiest way to capture fax #s for each individual document in a terminal services environment? Tag: USB Host controller on Windows Tag: 76853

    - Causes of USBD_STATUS_ISO_NOT_ACCESSED_BY_HW Greetings, I realize in my previous post "NEC B1 HC chokes with full BW USB2 ISO IN stream" my primary question was hidden in a flurry of details. Can I be doing something in my USB camera driver to cause the USBD_STATUS_ISO_NOT_ACCESSED_BY_HW error I am seeing with the NEC host controller? The only thing I have heard of that causes this error is URB starvation. That is clearly not the trouble. I am queuing 10 URBs of 32 packets each. Also, the driver works perfeftly under the VIA controller. Is there some subtle error I might be causing that effects the NEC controller but not the VIA one, or is there simply a bug in the NEC controller?

    - NEC B1 HC chokes with full BW USB2 ISO IN stream Greetings, I have tracked down a bug that looks for all the world like it is caused by the NEC B1 HC on the Adaptec USB2 PCI interface card I have. The host is a MP Athlon system running XP SP1 with the Adaptec card using the NEC B1 EHCI controller and a separate VIA EHCI controller on the mobo. Both controllers are using the Microsoft usbehci.sys driver version 5.1.2600.1243. When running a full bandwidth ISO stream from a USB camera (3072 bytes/microframe), the NEC controller chokes with USBD_STATUS_ISO_NOT_ACCESSED_BY_HW (c0020000). It does it horribly when running on a MP boot. If I run on a UP boot of the same machine (same HC driver), it is still there but not as bad. Now if I switch the camera over to the VIA controller, everything else I think exactly the same, the error goes away entirely. It is gone on both the MP and UP boots. Before I checked the VIA HC, I thought it was the camera being too slow and not responding to the IN token in enough time. But after seeing the difference with the VIA HC, I looked a little more carefully and saw on my bus analyzer that indeed the IN token is never sent. So it is clearly on the host end. It is always the third transaction in the microframe that fails; after two successful transactions. I was really surprised that a HC would fail like that. I looked online to see if there were any known troubles with that particular HC, but I did not see anything. Anyone have any ideas??

    - Device IO / Detect Drive Type HI My application needs to directly modify an attached Flash Device. (own FS on it) I am using physicaldive[nn] to open and DeviceIO(IOCTL_DISK_GET_DRIVE_GEOMETRY_EX) to detect the size of the card. (using the member "DiskSize") Is there a way to detect the drive's "type" in more detail ? I already have the information that it is a "removable" one, but I'd like to make 100% sure that it is a FLASH type. Are there any documened calls to retrieve more information about a given drive ? Or can I wrap an ATA Info command in an ordinary DeviceIO call ? TIA w.b. Tag: USB Host controller on Windows Tag: 76811

    - IRQL in TDI filter dispatch functions Hi I'm developing a TDI filter driver. a. According to the MSDN, IoCallDriver() can be called at IRQL <= DISPATCH_LEVEL. Therefore, should I assume that it is possible for all dispatch routines in my TDI filter to run at IRQL = DISPATCH_LEVEL? (According to MSDN this rule is right for all kinds of filter drivers?) b. My completion routines are being invoked in an arbitrary thread context and probably at high IRQ. Is this also right for a TDI filter? c. When code can run at IRQL => DISPATCH_LEVEL, all the allocations on the STACK also need to be none paged? (Do I need to use paged_code macro or something like that?) Thanks.

    - How to get started with creating a virtual filesystem? I would like to create a new virtual volume with a virtual filesystem, something that is visible as a drive, can be given a letter, and browsed in "explorer" etc., but where all requests to access files are handled by me, preferably delegated to a service in user space. What kind of component do I actually need to write, at a minimum? If I understand well, I would need to somehow create a fake volume and tell Windows (I/O manager?) about it, register my own filesystem and make Windows forward all requests to this fake volume to my filesystem instance, with which I would interact via ioctl. Is that correct? Could it be simpler? Is there a way to get there even faster with WDF? How about UMDF, does it have support for this sort of functionality?

    - Device Object Hello I got a function now that is executed on the following line: DriverObject->MajorFunction[IRP_MJ_DEVICE_CONTROL] = FilterDispatchIo; NTSTATUS FilterDispatchIo( IN PDEVICE_OBJECT DeviceObject, IN PIRP Irp ) In this function the DeviceObject is a ControlDeviceObject or a the main DeviceObject. When it's a DeviceObject is passed through to another function that's passing the IRP to the lower driver. If it's a ControlDeviceObject it's going to look if something is send from the user application. In this check im looking if my own made IOCTL is send or not, if so i want to add an mousepackage. The problem is i need to main device to send the package to but at this moment i get the ControlDeviceObject all the time. I also tryed to save the address of the Main DeviceObject and use it when i needed to enter the package, but i think that isn;t even possible since maybe it has something to do with the Passing through of the IRP and the completion of it(what maybe would explain the error)? I tryed alot of things now and i im stuck now, can anyone help me on the right way in getting the Main Device Object so i can add my own package? btw the error that i got all the time was DRIVER_IRQL_NOT_LESS_OR_EQUAL.

    - EngMapFile I have a mirror display driver that uses a memory-mapped file to push screen updates to an application that reads the updates from the file and sends them to a server for distribution. The user-level application creates the file and passes the name to the driver. The Driver uses EngMapFile to open it. Sometimes it fails and the application retries using a smaller size until it succeeds or reaches a minimum size and fails. I am guessing that EngMapFile fails because it uses non-paged system memory to back the memory-mapped file and since this is a limited resource there may not always be enough available for the full size of the file. Can someone verify this for me? The documentation for EngMapFile is very minimal. Thanks, Bill Wyatt, Sonexis, Inc. Tewksbury, Massachusetts. Tag: USB Host controller on Windows Tag: 76751

    - Issue while attempting to retrieve the file object's path name associated with process section Hi All, We encountered a issue while attempting to retrieve the file object's path name associated with process section object after renaming the folder that contains the executable image. File System: NTFS OS: seems like all x32 NT based (2000, XP, 2003 & their SP) Steps to reproduce: 1. Create a new folder named "1" on disk (for example, C:) 2. Copy any executable file (e.g., "test.exe") to the created folder. 3. Execute this application. 4. Exit from this application (e.g., "test.exe"). 5. Rename folder "1" to another name (for example, "2"). 6. Execute the application located in this folder ("2\test.exe") that was executed at step 3. What did we get? The new process is successfully running, however we can't get the correct path name for the section object associated with this process, and also we got the incorrect path name in the PsSetLoadImageNotifyRoutine callback routine (see below example #4). As a result of querying the path name of process section we got: \Device\HardDiskXXX\1\test.exe Instead of expected: \Device\HardDiskXXX\2\test.exe We tried the different methods of getting the path name for the section object associated with the process. All methods, except the reading PEB give the incorrect path name:( Example #1. PSECTION pSection; .... get section for process executable image .... PFILE_OBJECT pSectionFile = pSection->Segment->ControlArea->FilePointer; ObQueryNameString(pSectionFile, ......); Example #2. Use IoQueryFileInformation for file object associated with process section object or use ObOpenObjectByName AND ZwQueryInformationFile for this file object Example #3. Direct scan file object fields and get file path name. Example #4. VOID NTAPI _PsSetLoadImageNotifyRoutine( IN PUNICODE_STRING FullImageName, IN HANDLE ProcessId, IN PIMAGE_INFO ImageInfo) { KdPrint(("Load image: %ws\n", FullImageName->Buffer)); } EXTERN_C NTSTATUS DriverEntry( IN PDRIVER_OBJECT pDriverObject, IN PUNICODE_STRING pRegistryPath) { return PsSetLoadImageNotifyRoutine(&_PsSetLoadImageNotifyRoutine); } Basing on PDB information (ntoskrnl.exe) the unexported function MmGetFileNameForSection that is called before executing load-image callback routine got the invalid path name also.

    - Read Data from USB Hi all, I have a problem in reading the data packets from USB. I have got the USB from the Vendor(IXXAT) , and implemented the code to return handle for USB using CreateFile(). it is returning the Handle and Device path correctly but the BytesRead variable in ReadFile function is always zero. Can any one help me? I think i have almost reached the endpoint in reading the data. Thanks in advance samaya Tag: USB Host controller on Windows Tag: 76744

    - Unable to delete .sys file Hi All. I had posted this issue some times back. Can any one help me on this? This is the story: My driver is working fine as expected. But I am not able to delete the driver (.sys file) from drivers folder or overwrite it with another version , even after unloading the driver successfully !!!. Each time our custemers have to reboot the machine to do it !! Windows says,someuser mapped section is left, so I don't have the permission to delete it. I can delete the driver if I haven't run any user application on top of it. My driver code always runs and uses NonPaged memory pools. Driver is running on Windows XP machine with all driver verifier options enabled (of course without low memory simulation). It doesn't report any errors while I unload the driver. I could not see any resources left after unloading the driver (used Winobj, winmsd, process explorer etc.). And I haven't run Event Viewer. Can anyone suggest, how the application program can prevent deleting a driver file? Application interacts with the driver only through IOCTLs. It does not know .sys's name.

    - USB 2.0 High Bandwidth Iso I am having an issue with a USB 2.0 high-bandwidth iso endpoint. It isn't behaving the way I expect. The descriptor for the endpoint has the maximum bandwidth -- wMaxPacketsize of 0x1400, meaning 1024 bytes with 3 transfers per microframe. I had assumed that I would use this like any other isochronous endpoint, by sending it a series of 1024-byte packets, so that each microframe would consume 3 such packets. However, that does not seem to be what the host controller driver expects. I was VERY surprised to find that USBD_PIPE_INFORMATION.MaximumPacketSize was 3072, not 1024. Further, if I send it a series of 1024-byte packets, I get USBD_STATUS_INVALID_PARAMETER. It looks as though USBD will only schedule one URB per microframe. So why is this a problem? Well, let's say our data is coming in chunks of 2600 bytes, which means 1024 plus 1024 plus 552. We are using an FX2. Our data rate is lower than the maximum bandwidth. When the FX2 gets an IN token but its FIFO is empty, it does not reply. When that happens, I will get a packet with 1024+1024 bytes plus an error, followed by a packet with 552+1024+1024, but those bytes are all packed together. I can't identify the packet boundaries. So, is it a fact that USBD will only schedule one URB per microframe? Or have I missed something? -- - Tim Roberts, timr@probo.com Providenza & Boekelheide, Inc.

    - DIFxApp and unsigned driver I'm trying to use DIFxpp.msi to install an unsigned driver of non-WHQL (custom) class. I set the flag in MsiDriverTable to 8, and included the driver files to the corresponding component. But when the installer runs, only INF file is copied to DRIVERSTORE folder, not the SYS file, causing the setup to issue a prompt for SYS file. What could cause that?

    - IOCTL_INTERNAL_MOUSE_CONNECT Hello I already got a working IOCTL that gives me the info i need from my user application. And now i want that every time i send my own IOCTL with an x and y values for the mouse to execute the mouse_callbackfunctie and insert a self made package with the x and y from my IOCTL.. Does it take much time to replace the IOCTL_INTERNAL_MOUSE_CONNECT (located under IRP_MJ_INTERNAL_DEVICE_CONTROL) that triggers the Mouse_Callbackfunction with a own made IOCTL? I get my IOCTL with help of an control device and in that control device i get my data with help of the Home made IOCTL. I hope it's possible to answer. Tag: USB Host controller on Windows Tag: 76727

    - IR communication using non standard protocol Hi, I have an electronic device that communicates with my PC (running Windows XP) using infrared communication. The protocol it uses is like this: For instance to get a buffer status the PC can send B\r to the device, and the device will respond with something like B\r00\rOK\r if the buffer is empty. In other words you send the command to the device and it responds with the command, the answer to the request, and "OK". Currently I use an infrared transmitter connected to one of the COM ports in the PC to communicate with the device. In C sharp I have written a program that communicates directly with the COM port the device is connected to: I open the COM port, sends a command to the device, and waits for a response. It works okay but now I also want to use an IR transmitter connected to an USB port! Virtual com ports and IR is not a possible solution in Windows 2000/XP! Is there an IR communication class that makes it possible to write a program that uses the IR interface there is in Windows 2000/XP to communicate with any IR device - regardless of how it is connected to the PC (as long as it just has a driver)? I know there is something like this for (win)socket programming but will that be possible to use in this case/ with the protocol I described?

First of all, you need to read up on USB basics: http://www.lvr.com/usb.htm

(A) Read the USB core specification (www.usb.org)
(B) Read it again.
(C) Your target board has to be equipped with a USB device controller
(a B-plug). You connect this device controller to the USB host
controller (A-plug) on the PC side.

The PC has a USB host controller and your board has a USB host
controller. This is a no-go situation. USB is a master-slave bus and
allows only one master = host controller on the bus.
