    - why PassThru couldn't pass ChkINF test? When I tested PassThru, a sample IM driver in Windows 2003 DDK,with HCT 11.2 ChkINF, I found the following error "Line 33: ERROR: (DE22.19.4011) The AddService ServiceName parameter must match the NDI\Service entry in the Registry.

    - Trouble loading WIA minidriver DLL under Windows 2000 I have a problem related to a WIA minidriver. I'm not sure which newsgroup is the correct one for this; let me know if there is a more appropriate group. I've created a WIA scanner minidriver that loads and works fine on Windows XP. I also intend for this minidriver DLL to provide STI functionality in Windows 2000 and Windows 98. My problem is that this WIA/STI DLL is not getting loaded under Windows 2000 for some reason. The STI_Trace.log file contains only the following error line: e STISVC [stisvc.exe::0x65c] Could not open device ({6BDD1FC6-810F-11D0-BEC7-08002BE2092F}\0001) . Received from STI: hResult=(80040154). Object not maintained Win2K does not like my DLL for some reason. My entry point function never gets called. However, under Windows XP and Windows 98ME my DLL does get loaded. These are the only three Windows versions I've tried so far. I do have two other working minidrivers I can use as references. One, of course, is the DDK WIA sample scanner minidriver. The other is an existing scanner product that currently works under Win2K, although its STI DLL was not built by me. I believe that my INF file is correct and the registry entries all look good to me. Anyway, to rule out those possibilities, I decided to install the other working scanner product and then rename and substitute my own WIA DLL in place of the other DLL. When I did this, my DLL was still not loaded. But when I substituted the WIA sample scanner DLL, that DLL is loaded ok---its entry point gets called. It's only my DLL that will not get loaded. So there is apparently no problem with the registry, and the DLL can be found. It just won't get loaded and get its entry point called for some reason. I then compared my DLL with the WIA sample minidriver to see what could be different. I built both using the build utility and the Windows XP SP1 DDK, build 2600.1106. I initially had a different entry point than the sample scanner. I was using _DllMainCRTStartup because my DLL uses the C runtime library---in fact, it uses STL as well. So normally I see my DllMain() function get called by _DllMainCRTStartup . But to make sure this wasn't the problem, I made my entry point to be "DllEntryPoint" to match the WIA sample code (remembering to specify DLLENTRY=DllEntryPoint in the sources file of course). But this did not help. I checked the exports (using DUMPBIN) to make sure both DLLs have the same exports. The only difference is the DliHook export in the sample minidriver, but that should not matter. I then compared the "sources" files. Mine is almost the same as the sample minidriver's. There are only two differences. Since I'm using STL, I need to set USE_STL=1 and USE_NATIVE_EH=1. Other than that they look the same. So why does my DLL not get loaded under Win2K?? It should not be a problem with a GUID---the DLL entry point does not even get called. So Windows doesn't even know anything about the GUID yet. The only thing I can imagine is that my entry point looks different in some way, maybe of because the way it was compiled. But I cannot see any significant difference between how my DLL and the sample minidriver are built. Tag: questions about USB bandwidth consumption under Windows2000 professional Tag: 35880

    - Capturing Unicode string in DrvTextOut Hi, I am writing a virtual printer driver for WinXP. In DrvTextOut(), I need to capture and record the Unicode text string to be printed. Sometimes, this string is contained in STROBJ->pwszOrg. However, when STROBJ->flAccel contains SO_GLYPHINDEX_TEXTOUT, "pwszOrg points to an array of glyph indexes, rather than a Unicode array." As hard as I tried, I could not figure out how to convert this array of glyph indexes back into Unicode characters. Am I missing something here? Please help! Regards.

    - a keybaord/mousr filter driver Hi, After reviewing some website (http://www.sysinternal.com) I programmed a keyboard/mouse filter driver. But there is something strange. I have a global variable to control whether to ignore keyboard scan code: if (ignore) { for (i=0; i<numOfKey; i++) KeyData[i].makecode=0; } I initialized the variable "ignore=0" in DriverEntry but once I rebooted my PC, the driver starts working and my keyboard does not have any respond. It seems that the variable ignore is non-zero even I initialized it with zero!! Can anoyone help? Tag: questions about USB bandwidth consumption under Windows2000 professional Tag: 35875

    - Parallel port direct i/o? Hi, is it possible to program the parallel port with system-supplied drivers? The DDK help says something like "raw access to ports", but it seems it is only for controlling printers. I need to program the port directly, i.e. setting and releasing port lines. At the moment, I'm using this "user-mode- security-hack-driver" and inb/outb calls. Do I have to do these inb/outb calls in kernel mode to have a reliable communication without scheduler- interrupts? I'm doing time-critical communication over the port but the scheduler switches in stages where it mustn't. Are kernel drivers "safe" from unwanted scheduler switches or would it also don't work? Thanks for your help. Thomas Tag: questions about USB bandwidth consumption under Windows2000 professional Tag: 35858

    - USB performance I have been measuring the performance of a USB 2.0 device we have developed and a driver based on the code provided in the Walter Oney book and discovered some strange things. 1. On dual processor machines, the throughput is 50% greater when one of the processors is removed. This is under Windows 2000 SP4. 2. On some machines, the throughput is more than twice as much under USB1 than under USB2. This is generally with USB1 ports integrated on the motherboard and with a PCI USB2 card. This has only been observed under Windows 2000, never under XP. I wonder if anyone else has observed similar behaviour, or has ideas as to how I could investigate further.

    - USB MIDI device driver development I'd completed the design of the hardware side of a USB MIDI music keyboard. However, I have no idea what will be the Windows XP device driver development. I read some books on the Windows WDM already but still have no idea. I understand that Windows XP/2K had USB-MINI class driver but don't know what else is needed? Can someone give me some pointer on what is needed? I had experienced in the VxD but not WDM Thanks Kan. Tag: questions about USB bandwidth consumption under Windows2000 professional Tag: 35836

    - Do GCAPS_VECTORFONT and GCAPS_HIGHRESTEXT work, and if so how? Neither of these seem to function, at least on Win2K they don't. No matter if GCAPS_VECTORFONT is set the vector fonts always come through DrvStrokePath instead. And even if GCAPS_HIGHRESTEXT is set the coordinates for placement are just as LONGs, not at FIX resolution.

    - Device Driver Hard Drive emulation Hi I hope this is the right place to ask this. I have a client with a collection of operating systems, one of which is an AS400, and I would like to right a bit of software that would allow a windows machine (98/ME/2000/XP they have a whole collection) to think that it has a hard drive, but it is in fact a network type of share. Do I need the DDK to do this, and what would be the best approach, writing it so that it could use the "map drive" type interface, or do a hard drive emulator, must like Deamon does with CD-rom drives? Any help and pointers in the right directions would be greatly appreciated. Are there any Books on the subject etc. Thanks Vaughan Tag: questions about USB bandwidth consumption under Windows2000 professional Tag: 35802

    - Reboot without bluescreen I am working with 1394 device driver over windows 1394 bus driver. I kept night long testing for Isoch send requests. There was debugger on a serial port. My target PC rebooted sometime in the night. There was no bluescreen. No error displayed on the debugger. If BSOD occurs, it should break into my debugger which caught only one print regarding reboot "Shutdown occured". There are few prints before which suggest very strange pattern of events occured. My "surprise remove" called. Later "Add Device". Again "Surprise remove". Then later shutdown and no blue screen. I am sure no one removed 1394 device cables. Is there any chance why "Surprise remove" occured on its own. If there is reboot without BSOD, how can I check. How can I make windows always give me BSOD for error. I even have "complete memory dump" set in recovery console. This is not dumped even. I also have driver verifier selected for my driver. Any clues ? Everything worked as though I removed cable, connected it, again removed and then restarted my PC..I dont think I came to lab in my dream :) Thanks.

    - device driver installation application in XP and Win9x I need to write an application to install my WDM device driver. The user will insert installation media before he plugs in the device. So when he plugs in the device for the first time, the device installation will be completely "silent". 1. For Windows XP, I followed the instructions in DDK. I use "SetupCopyOEMInf" function to copy my INF file to %windir%\inf foler, and a PNF file is generated too. However, when I plug in the device, the "New Device Found Dialog" still pops up. According to DDK, this should not happen if the PNF file is alreday generated. Is this because my driver is not digitally signed? 2. For Windows 98 SE, the "SetupCopyOEMInf" dosen't work. Is there a way to write a device driver installation program for Win9x/Me to install the driver before the device is plugged in?

    - Driver hang after IRP_MN_START_DEVICE Hi all, I have a PCMCIA card driver and it hangs at the irp after the IRP_MN_START_DEVICE. I believe it is some irp that queries the interface but my driver just simply pass these irp down to the lower drivers. So I wonder what is causing the hang? What the irps after IRP_MN_START_DEVICE for? Thanks Tag: questions about USB bandwidth consumption under Windows2000 professional Tag: 35775

    - XP failing to enumerate HID devices I am having problems getting some versions of XP to enumerate HID devices (using the normal SetupDIxxxx functions). It is not just my code, or my hardware, as I can't even get the standard DDK Hidclient example to enumerate standard HID mice or keyboards on these machines. The machines I am having trouble with are running "XP Professional Version 2002 Service Pack 1". I have tried to replicate this on other machines with the same OS, but without success. The devices are working perfectly, and appear in the device manager correctly. I can even use Devcon to see them quite happily (using "Devcon listclass hidclass"). Anyone else experienced this or have any ideas? .... it is causing me a real headache as I've tried everything I can think of to get round it.

    - What does 1394 bus driver ALLOCATE_ADDRESS_FLAGS_USE_COMMON_BUFFER flag mean? I just encountered an undocumented value for the u.AllocateAddressRange.fulFlags value in the Microsoft 1394 bus driver IRB data structure, in the Windows XP DDK 1394.h file. It is ALLOCATE_ADDRESS_FLAGS_USE_COMMON_BUFFER, with a value 0x2. What does this mean? I can't find any documentation for it anywhere.

    - MS iSCSI software initiator Hi All I am developing a SCSI port filter driver. This driver works fine with other SCSI ports but there are some problems when used with MS iSCSI software initiator. When we send an SRB with SCSIOP_INQUIRY request to a SCSI device through the port device, the port returns STATUS_UNSUCCESSFUL (which does not explain the problem). When we send the same request through the PDO that was created for that specific SCSI device, it never returns. It also does not return IOCTL_SCSI_PASS_THROUGH / SCSIOP_INQUIRY requests. Does the iSCSI initiator support SCSIOP_INQUIRY requests? Why does it fail our requests? Thanks, Gregory Tag: questions about USB bandwidth consumption under Windows2000 professional Tag: 35732

    - how to uninstall default driver and install my own? I have to develop PCI card driver for our custom wireless card. My role is to develop PCI device driver. As I do not have hardware currently, I'm thinking of testing my driver using existing network card - RTL8139(A) fast Ethernet. To do above, I uninstall driver provided by Microsoft. And When I restart the PC for installing my driver, default driver is installed again already. I went to registry also and made changes, but without any advantages. Could somebody pour some light on how to uninstall default driver and install my own? TIA, Sanjeev Tag: questions about USB bandwidth consumption under Windows2000 professional Tag: 35700

    - Orientation disoriented Hello, I'm writing a printer driver. It's very generic except for the small amount of custom stuff I needed to add. I think the problem is in the <generic> code. If I print a document that has three pages, for example, the first is portrait, the second is landscape, and the third is landscape the problem occurs. The first and second print correctly, but the third always prints out as portrait. Beyond that, if the document has more pages, they will all remain "portrait" even if I used page setup to make them portrait. If I print directly, the problem does not occur, it only happens when I choose to spool. Preview works fine as well. It seems that the default devmode is being copied back over to the current devmode just before the third page prints. In general, it will only print the first "landscape" page correctly and then forever print portrait. I think my drvDocumentPropertySheets function may be the problem, I don't show the property sheet dialog to the user, but must still handle the calls to the function from the O.S. Is it possible to have the DM_COPY and DM_MODIFY flags both set on the same call? If so, do I copy the pdmIn param to my internal devmode AND copy the internal devmode to pdmOut? If so, it seems logical to update the internal devmode first then copy it to pdmOut, rather than the other way around. True? I've looked at the DDK plot example, but it doesn't seem to apply. A sample drvDocumentPropertySheets function that does not actually show an interface would be most helpful. Wishful thinking department: I hope this is one of those "Oh yeah, I've seen that a hundred times, here's the fix." type bugs. Any takers...please.

    - accessing pcmcia function control registers, xp First, some background. I've got a custom pcmcia card based on an old memory card. The card contains the usual flash memory for the disk (which I do NOT use or even care about) and then some custom stuff that hangs off of I/O space. The tuples in the CIS are correct but do not contain the required resources. My driver is implemented as a filter driver on top of memcard.sys. I handle IRP_MN_FILTER_RESOURCE_REQUIREMENTS to add my I/O requirement and also add the DevicePrivate resource that dictates stuff like wait states and width. I then get the assigned I/O resources when START_DEVICE comes through my filter. Looking at a debug version of pcmcia.sys with the debug mask turned on full, everything looks ok as my card is installed. It sees my memory window, it sees my I/O range, it has the right values in the config resource section of the output, it correctly reads my tuples and knows that I have one function control register (FCR). It _seems_ happy. Now for the "but" everyone is expecting. Part of the project's functionality requires that I be able to change that first FCR (the Configuration Option Register) dynamically as dictated by the actions in a user program. Everything I've read says the function control registers are part of attribute memory and sit just after the 512k area reserved for the CIS tuples. My approach is to issue an IRP_MN_READ_CONFIG to device I'm filtering to read all of attribute memory (length of 513 - 512 for CIS and 1 for FCR), change my single register and issue an IRP_MN_WRITE_CONFIG to change attribute memory. Doesn't work - if I issue a second READ_CONFIG after I've done the WRITE (which returns STATUS_SUCCESS), the data starting after the CIS area is back to its old value. In fact, I issued a READ_CONFIG with a big buffer and it contains the 512 CIS area repeated over and over for as big as the buffer. My WRITE has no affect. If I can't set this register on the fly, this whole effort is useless. My question - how do I write to that first FCR? Windows XP, SP1 Thanks, Judy (cross posted to OSR's ntdev list) Tag: questions about USB bandwidth consumption under Windows2000 professional Tag: 35672

Hi,

I have some questions about USB device bandwidth consumption under platform
of Windows2000 Professional.

1/ How does OS calculate each USB device bandwidth consumption?
2/ is there any relations between the bandwidth consumption and the driver
of USB device ?
or the bandwidth consumption is only determined by USB device?

Any advices are appreciated!
