    - Is that true? Microsoft website (http://www.microsoft.com/whdc/ddk/winddk.mspx) said that "Microsoft Windows XP SP1 DDK is not supported", but "Microsoft Windows 2000 DDK is supported".

    - Filtering Read Hi, I am modifying a upper volume filter driver (similar to diskpref). The operation i am trying is to filter the read. In IRP_MJ_READ i try to block the IRP and then issue my own read IRP to read some data from the disk and then return my read buffer with the original IRP. Now the problem I am facing is the new IRP I am sending down is returning status pending. And after that the system becomes unstable when i try to wait for the IRP completion :( . Can any one help me getting to the bottom of this problem. Is there any i/o mgr restriction that only one read irp can be sent to the underlying device at a time? Please help. Praveen.

    - Unidriver conflict warning problem Dear ALL: I'm developing a driver based on Unidrv. I have a problem as follows: After opening Printer Preferences property sheet, I go to "Paper/Quality" tab, then I go back to "Layout" tab and check duplex(print on both sides). Conflict warning signs for media types such as transparency does not display immediately in the media list box. The warning signs will come out after I select the media type as transparency, click apply and let the system solve the conflict. Also, the conflict warning signs will display correctly if I do not go to "Paper/Quality" tab before checking duplex. I checked .gpd file. It should be correct. I suspect it might be the problem in my ui plug-in dll. Can anyone give me a suggestion? Thanks. Tag: What must I do to trigger Autorun on my USB storage device? Tag: 38293

    - UpdateDriverForPlugAndPlayDevice not working in Server 2003 I have an application which launches the installation of my driver using the UpdateDriverForPlugAndPlayDevices function. Under XP Pro SP1 it works as expected. However, under Server 2003 SP1 the device does not install, even when logged in as the administrator. It appears from the setupapi.log that the error is related to my CoInstaller indicating that the default action to should be taken in response to the DIF_REGISTERDEVICE callback request. According to the Server 2003 SP1 DDK, the request is documented as "Can Handle" for Class Installers and CoInstallers, not "Must Handle". So the question is why Server 2003 is finding the default action should be performed response as not acceptable? Tag: What must I do to trigger Autorun on my USB storage device? Tag: 38289

    - Loading lower filter on disk devices. I have a lower filter driver that I would like to attach to the DiskDrive device class ({4D36E967-E325-11CE-BFC1- 08002BE10318}). Unfortunately, when I try to load it on this device class, the system will crash during the boot process. The stack trace indicates the fault occurs in nt! IopMarkBootPartition. It does not seem that any code in the driver itself, even DriverEntry, is ever getting called. The same drive will load and function if it is attached to the CDROM device class ({4D36E965-E325-11CE- BFC1-08002BE10318}). Is there some trick to loading lower filters on DiskDrive device that I don't know about? Tag: What must I do to trigger Autorun on my USB storage device? Tag: 38286

    - how to prevent OS from picking the old INF over new one Hi, everyone! I am having a problem with automatic driver installation. Namely, I followed the general guidelines from the DDK examples when pre-installing the drivers: I copy the INF with SetupCopyOEMINF to the Inf directory. Everything works fine until the time when I need to install the updated version of the driver. If I copy another INF with a different DriverVer (new date and version), the OS invariably picks the first INF (oem1.inf and not oem2.inf). Setupapi.log records the fact that since the driver is unsigned, the date is ignored. I know that if I manually delete the old INF, the OS will pick my new one (oem2.inf). But I want to avoid scanning through every INF to see which ones can be deleted. Our device is used for highly specialized purposes and works only with our software, so there is not much hope for getting it signed. What can I do to my new INF to make sure that the Configuration Manager picks the newer one every time the automatic device install runs? Are there any other options for me? -igor.

How do I avoid this ? 2) When updating the language monitor, I need to reboot for changes to take effect. Is this how it is supposed to work ? 3) When I use SetPort with an error, the spooler isnt notifyed unless Im printing When I try to print later, the spooler is halted ( as expected ) but I dont get a status telling me what is wrong I use custom errors, ie settings the string member in SetPort PORT_INFO_3 structure Any help ?

    - Microsoft EHCI driver & Multiple URBs Hello, There seems to be a problem of posting concurrent URBs down to the USDB when working with high a speed devices over Microsoft EHCI driver - Sometimes the second pending IRP never completes. In a message from Alexander Grigoriev posted here it can be understood that this is an issue of Microsoft EHCI driver. We are using the latest EHCI driver from Microsoft on an XP SP1 Os (Driver ver: 5.1.2600.1106) with a USB2.0 hub based on Ali chipset. Replacing this driver with the driver from the USB2.0 hub vendor (Ali in our case) solved the issue. Has anyone had a similar problem, has anyone managed to send multiple concurrent URBs to the USBD (with high speed device over Microsoft's EHCI driver) without the driver getting stuck? Any info suggestions or comments regarding this issue will be highly appreciated. Regards, Yariv Ze'evi. Tag: What must I do to trigger Autorun on my USB storage device? Tag: 38262

    - FSD Filter Hi, I am modifying FileSpy from IFSKit to enable me to hide files/folders. Everything is working fine except one problem. When my completion routine is called with just one file entry (SL_RETURN_SINGLE_ENTRY set) which I want to hide, I issue another request to get the next file entry. If another file entry exists, the file I want to hide get's hidden properly. If no next entry exists, I return NO_MORE_FILES from the completion routine. The problem is that the user mode seems to ignore this error status altogether. I can still see the file entry for which I returned NO_MORE_FILES (in IO_STATUS_BLOCK). I am properly setting the Information field of iostatus block to zero. If I zero out the buffer for this request, I can still see a folder/file named '0' ! with all it's information (time/attributes etc.). Any clues on what I am missing?

    - 2 Kewaitforsingleobject which waits for same event. Hi, everyone. I posted a message a week ago about ExFreeToNPagedLookasideList. But I found that another matter and maybe above function does not have any problem. KeWaitForSingleObject was used as follows ------ int function A { KeWaitForSingleObject(&Event, Executive, KernelMode, FALSE, NULL); ... KeSetEvent(&Event, 0, FALSE); return int; } static VOID NTAPI function B { KeWaitForSingleObject(&Event, Executive, KernelMode, FALSE, NULL); ... KeSetEvent(&Event, 0, FALSE); +++++++ Call Function A(); } In this case, I thought that Function A will be called after executing function B. But when I debug, event (+++++++) was got in function B in sometimes... my thought : [B -> A] -> A or B debug result : [B -> B] -> A -> A or B (sometimes) Is there any method to solve this problem?

    - Usb isoc transfers and meaning of StartFrame Hello, What I see is the following. The first line is my data stream which consists of packets of 3 frames (ABC is one complete data packet). The second and third lines are from the Urb in the completion routine. Data A x x B C A | B ... IsoPacket.Length 17 0 0 17 17 17 | 17 ... StartFrame 100 | 106 ... The part that's confusing me is that the Data portion looks as though frames 101 and 102 did not occur at all. But the StartFrame member in the next Urb says that they were in fact 6 frames. I would assume that either the Data portion should be A x x A B C | A, or that StartFrame would be 104. Has anyone seen this before, or would hazard a guess as to what is going on? The platform is WinXP, and the device is a USB1.1 device. Thanks in advance, Todd Tag: What must I do to trigger Autorun on my USB storage device? Tag: 38247

    - IoCallDriver take long time for USB transaction? I just wrote one USB 2.0 driver for our usb device, we use bulk pipe for receiving and transmitting (one in bulk pipe and one out bulk pipe). I found one problem, IoCallDriver take long time, based on my measurement, this single function call will take average around 30 microsecond (max time is 150 microsecond). My TransferBufferLength is 1536, and I can transmit/receive total 16 Irp in one millisecond (200 MBPS throughput), but IoCallDriver will take total 480 microsecond, it eat almost 50% my CPU time (my system is IBM T40 with 1.3G pentium M CPU), it really not make sense because my entire system become super slow. Anybody know why this single function call take so long time and how can I reduce it? Thanks in adavance Long Tag: What must I do to trigger Autorun on my USB storage device? Tag: 38245

    - Dynamic Disk info -> need IFS? [Posting here because we're doing this task via a device driver.] Our goal is to find out what (perhaps remote) disk volumes are being used by a set of applications. With Basic Disks, this is not a problem (but they're local). When an application uses a file on a dynamic disk volume, we can -- by using ObQueryNameString() on the file and device handles from a kernel FILE_OBJECT -- see a file handle, as referring to, say, \Device\HarddiskDmVolumes\PhysicalDmVolumes\BlockVolume1 \skyzx.txt but with QueryDosDevice() and such we get that F: (which I know a priori to be the drive letter in this case) is \Device\HarddiskDmVolumes\MachineNameDg0\Volume1 (Dg==DiskGroup) So does anyone know how we can match those two up? Either the two paths or the first path to the drive letter. I've seen no available API or documented dmio.sys IOCTL that can tell us this, so I had hoped that we could match the last part ("Volume*" == "BlockVolume*") but we've seen those be inconsistent, so either we're going down the wrong path or else we just need a smarter matching algorithm. Any suggestions? (I have spent some time looking, so I'm pretty sure it's nothing *too* obvious). Would something in the IFS (Installable File System) definitely provide us this information? Windows 2000 and later. And at this point I'm not worrying about local (i.e., private) mount points.

    - newbie questions Hello I am reading "the windows 2000 device driver book" in order to learn win2k device driver coding. I have a few questions. 1. When I installed the ddk, it created a directory structure like this: d:\winddk\2600.1106\ bin\ debug\ inc\ etc. Should I move everything in the directory 2600.1106 up a level, or should all my include path's refer to 2600.1106? 2. The book has some sample code and tools. The readme for the cd says to move the contents of the tools\DDAppWiz.awx file to the ...\Microsoft Visual Studio\Common\MsDev98\Template directory in order to use devstudio appwizard to build device drivers. I am using visual studio .net 2003 and I don't have this directory. I don't have any .awx files in my devstudio directory either. Where should I put this file? 3. The book says to build the chapter 6 files as a test of my installation. It also says to modify the system properties to match the location of your ddk. I made the below changes to include path and lib input path, but I still get this error during the link: Additional Include Directories = d:\winddk\2600.1106\inc\ddk\w2k;d:\winddk\2600.1106\inc\ddk\w2k Additional Library Directories = d:\winddk\2600.1106\lib\w2k\i386 The error is = Linking...

    - Surprise Removal problem in NDIS-WDM Drivers in XP SP1a Hello Everyone, I am resending this message as I didn't get any reply. I am sure at least one of you might have faced the same problem. I am developing a NDIS-WDM (USB) driver for my USB Device. I followed the sample for NDIS-WDM driver given by Eliyas. I browsed through the Mailing Lists and found that for making the Surprise Removal work, I have to set the NDIS_ATTRIBUTE_SURPRISE_REMOVAL_OK bit while calling the NdisMSetAttributesEx function in my MiniPortInitialize function. I did this. But to my surprise, the "Safely Remove Hardware" icon in the system tray still was coming. I tried a lot to debug. Then later I reinstalled the Windows XP. Now I found that the "Safely Remove Hardware" icon does not appear in the system tray when I connect my device and load my driver. Now, I applied the Windows XP Service Pack 1a and rebooted. After rebooting, the "Safely Remove Hardware" icon appears again in the system tray. This concludes that Windows XP Service Pack 1a is containing some modifications to the NDIS/WDM framework which makes this feature of Surprise Removal not work. Am I the only one facing this problem? Please correct me if I am wrong somewhere in my analysis or debugging. Any pointers in way of URLs or documents would be of great help to me. Thanks in advance, Best Regards, GNRaj Tag: What must I do to trigger Autorun on my USB storage device? Tag: 38227

    - USB2.0 concurrent URBs Hello, We're developing a miniport driver for a USB2.0 NIC that supports High/Full speed (Bulk eps). The miniport receive packets from NDIS and passes them as soon as possible to the USBD - resulting in several concurrent OUT URBs pending all the time. Also, the miniport maintains several (3-4) IN URBs pending at all time. The Problem is that when we test it at high speed (Ehci controller) after a few hundred packets the IRPs fail to complete and on the bus we see that no more OUT or PINGs are posted. We serialized OUT packets so only one OUT URB is at USBD at any time, this solved the problem but gave poor throughput on the bus. This problem does not happen on when we connect at full speed (on an OHCI controller). We are testing on an XP SP1 machine. Can someone please help with this issue? Regards, Yariv.

    - how does "plug & play" run and install the driver for the device? I've bought a 7 in 1 USB card reader/writer, but the windows 2000 Professional on my IBM Thinkpad T30 considers it as a SD/MMC reader/writer and install the "USB mass storage device"(usbstor.sys) under "Universal Serial Bus Controllers", "Generic SD USB reader device"(disk.sys) under "Disk Drivers" and "Generic Volume" (no driver) under "Storage Volumes". So only SD/MMC card reader is functional. This card/reader DOES work well on some machine not only for SD/MMC, but also for CF,MS, etc... I want to know how can I let the system know it is a multiple card reader instead of SD/MMC card reader only. TIA jamesyang@163.net Tag: What must I do to trigger Autorun on my USB storage device?

    - How to communicate with a HID device from virtual COM driver? I have created a virtual COM port now, it can be read/write by HyperTerminal or other application. I want to redirect data to a HID device, but I meet a trouble. My virtual COM driver is written for a HID device, when plug in the HID device, a virtual COM port will appears in Device Manager, but this virtual COM port will take the HID device's place in Device Manager and the HID device can't be seen from Device Manager. I am puzzled that if the HID device can't be seen from Device Manager, is there any way to communicate with this HID device in virtual COM driver? How can I use HID driver(hidusb.sys, hidclass.sys...) to communicate with HID device if the device can't recognized by Device Manager? Could any one help me for this trouble?

    - Issues to update Ndis IM driver Hi, I tried to update NDIS IM driver by uninstalling first and then reinstalling. I was running the error message "Error 1072: The specified service has been marked for deletion." while updating IM driver by using INetCfg to uninstall and reinstall. I tried to reproduce the error by using Microsoft DDK provided sample NDIS IM driver "Passthru". I installed the "passthru" IM driver by using MS network GUI applet. After the installation, I reboot the machine. Then I uninstalled the "passthru" IM driver by using MS network GUI applet and reinstalled without reboot. At this point, I got the "Error 1072: The specified service has been marked for deletion." (by looking the logfile setupapi.log). Could you help me to indetify the problem? or Any known issue about it? This problem only happened on Windows XP. I tested under Windows 2000, everything worked fine no matter by using MS Gui applet or using INetCfg.

    - Setting WLAN SSID/Channel programatically I have a requirement to set the SSID and channel of a wireless NIC from a user mode program running on XP SP1. Having reviewed similar posts in these newsgroups it seems there is no way to do this (on XP SP1 anyway) apart from writing an NDIS device driver that would load/attach the lower level NIC device driver and then use NdisRequest to make the required changes. Assuming I went to these extraordinary lengths just to change two settings, my question is, after the SSID/channel had been modified, would the changes be permanent, i.e. persist after a reboot? If not then the driver would always have to be loaded at the appropriate time and make the changes to ssid/channel. Of course any pointers on where to start with this would be appreciated. My thought so far are: 1) use the DDK passthru sample as a starting point 2) use the extended passthru sample (added DeviceIOControl) by Thomas Divine then I'm stuck, having never written a device driver before. If using NdisRequest can make permanent changes then I want to: 1) dynamically load and open my device driver 2) use DeviceIOControl to instruct my driver to load/attach to a specified driver (already loaded) 3) instruct my driver to make the changes to ssid/channel. If I can't make permanent changes then I guess I need to have a driver which is always loaded on top of the specified NIC driver when it is loaded. The required changes would then need to be applied.

I am looking for some infomation that would help me make
my installation program automatically execute from a USB
Flash Drive. I found some information in MSDN the
following is an extract of that
----------
If you need to make a USB storage device that executes
Autorun, the
following two conditions must both be true:

. Media must be marked as removable.

. The device can be set to either static or removable.
-----------
The complete information can be found at this location
http://www.microsoft.com/whdc/hwdev/bus/USB/usbfaq.mspx

The problem is that incase of a USB storage device the
media may not be marked as removeable. My question,
1. Is it possible to fool windows by specifying removeable
media even for USB drives by burning the media type as
removeable on the device itself?
2. Does windows read the media type information from the
device or it simply ignores the value of the media for USB
drives?

Any help would be appreciated.

Thanks,
Rajesh
