 - USB Modem device Hi, We have a USB modem device, which is acually a GSM/GPRS phone. The GSM/GPRS part may need the PIN code for the SIM card in order to make calls. Se when the initialization command has been sent, we must ask the device if it it needs the PIN, and present a dialog if it does. How can we accomplish this? Please direct me to relevant documentation or newsgroup. Leo Havmøller. Tag: USB Modem device Tag: 40903

 - Unidrv: Custom Halftoning on Windows NT Since The *HTCallbackID does not work on Windows NT, we have hooked the IPrintOEMUni::ImageProcessing() callback to apply the custom halftone pattern This Unidrv based PCL driver is for a monochrome printer. The values in our custom halftone pattern are in the range of 0 to 255. Hence to apply this pattern we have the following values in the ColorMode feature of our GP *Feature: ColorMod *rcNameID: =COLOR_PRINTING_MODE_DISPLA *DefaultOption: Mon *Option: Mon *rcNameID: =MONO_DISPLA *Color?: FALS *DevBPP: *DevNumOfPlanes: *DrvBPP: *IPCallbackID: 334 We *have* to convert the source DIB to 1BPP and give it back to the UNIDRV after ImageProcessing() returns. The indexes in the pSrcBitmap to the pColorTable where converted to grayscale values using the formul greyvalue = rgbRed * 0.299 + rgbGreen * 0.587 + rgbBlue * 0.114 We tried dithering the 8BPP grayscale DIB using Flyod-Stienberg algorithm, but are not able to reproduce the same quality DIB the UNIDRV gives us when the *DrvBPP is Are we missing something How does GDI do the dithering from 8BPP to 1 BPP Is it possible to dither 8BPP greyscale to 1BPP Monochrome image of the same quality as GDI's dithering Tag: USB Modem device Tag: 40899

 - Question about using IoGetDeviceObjectPointer() in Win98 Hi, All, I develop a WDM Driver that in the AddDevice()£¬I use IoRegisterPlugPlayNotification() to register listen to an USB device's insert/remove.In its callback function, I use following code to get the DeviceObject£º if(IsEqualGUID(dicn->Event, GUID_DEVICE_INTERFACE_ARRIVAL)) { status = IoGetDeviceObjectPointer( dicn->SymbolicLinkName, FILE_ALL_ACCESS, &pFile, &pdo); ................. } I found that in win 2000£¬the pdo return back is tha same as the DeviceObject of the lower driver. So after that, the IRP build by me can be successfully send to the lower device¡£At this time, the dicn->SymbolicLinkName looks like \??\USB#Vid_6513Pid_0089#51e37dc9701#{guid} But in win98, the same codeget different result. IoGetDeviceObjectPointer £¨£©return NTSUCCESS£¬but the pdo return back is different from the DeviceObject of the lower driver. The IRP build by me£¬can't be send to lower driver by IoCallDriver()¡£what's the problem? this time £¬the dicn->SymbolicLinkName looks like \DosDevice\0000000000000002\{guid} Further more, I found that, in win 2000, when I call IoGetDeviceObjectPointer(), the lower driver will recieve an IRP_MJ_CREATE. But in win 98, the lower one can't recieve that IRP. why? It seems so strange. in win98, the IoGetDeviceObjectPointer() can return success, and give a pdo to me, but I can't use it. Could anybody be kind enough to show me some light in that? Thanks in advance! Tag: USB Modem device Tag: 40894

 - Need Help on POSUSB Hi , I am implementing a Virtual Com port driver for our Target Device on WinXp. For this, I have taken the reference driver code from Microsoft POSUSB The issue is that while doing an install / Uninstall or Enable / Disable of the Virtual Com Port, the OS asks for a system restart. I am interested in knowing if this is an acceptable behavior as we are planning to do HCT validation of the driver. We have referred to the HCT documentation for the same, but in no place does it say that this restart is acceptable. Unfortunately, I have not been able to find how serial port emulation can be done without the above said behavior. when i Disable/Enable or Install/Uninstall the device, i am not handling the RemovalRelations in the IRP_MN_QUERY_REMOVE_DEVICE.i am just passing that IRP down as STATUS_SUCCESS. after that i am geting IRP_MN_CANCEL_REMOVE_DEVICE this is because of bus driver not process it proper. But as per Documentation you need not worry about this IRP. I would be very grateful if you can guide me in this regards. thanks in advance Regards, Deepak. Tag: USB Modem device Tag: 40892

 - Writing storage device driver for a flash PCI card Hello, I have a PCI adapter that has flash memory on it. I know everythings about this card, including the PCI manuf device ID, the PCI config register, and how to read and write from/to the flash memory. I want to write a driver for it such that when I open windows explorer I will see my card shown as drive D: (or E: if there is a CD rom in the system). I have been reading books, including Programming the MS WDM 2nd, Oney, and the DDK documentation from the lastest DDK for Window 2000/XP. Too much information has made me confused. 1. Should I write the SCSI mimiport driver that will layer below the scsi port driver? I read about this SCSI miniport things but it's really confused. I have thought about this but when I look at the functions that I have to implement shown in the DDK, it is too complicated. My PCI card does not use DMA and IRQ. It only need two 32-bit registers and a 4k memory range and an IO port that is part of the PCI config space. 2. What are the alternatives? Port driver? I thought my driver must be a port driver, since it must tell the system how to read and write to the PCI register. But it must contain a layer that tell the system that my drive is a D: drive. Anyhow, this whole thing is a mess in me right now. Can someone explain or show me what the best approach to this? Thank you so very much. Long Tag: USB Modem device Tag: 40880

 - Keyboard mouse stream separation - again... Hello folks, again I am having a few questions belonging to my previous topics. I want to separate keyboard and mouse streams originating from different devices - Windows shall only get the information of one device combo. The others shall be used for whatever. I have written adopted DDK filter driver examples for PS/2 chain. This works but is a bit dirty. The DDK also contains the original "keyboard class" and "mouse class" drivers. Wouldn´t it be possible to adopt them to deliver this feature? How are those driver examples installed? DDK help says that they are protected by system driver protection... How can you prevent XP from caring about those drivers? Many thanks for your help... Volker Tag: USB Modem device Tag: 40878

 - Win98 unidriver/landscape mode banding Is there anyway to get a vertical banded RGB data in Win98 unidriver ? I set sPlanes=1, sBitsPerPixel=24, thus a fnOEMDump() function is required. Unidriver bands portait pages in printing direction, that's fine. Problem raises when i print with landscape mode: If i set MD_LANDSCAPE_GRX_ABLE in fGeneral, it will band landscape page horizontally, which is not the printing direction. If i clear MD_LANDSCAPE_GRX_ABLE in fGeneral, UniControl() returns the whole page dimension at 1st time NEXTBAND was called, and returns empty rect at 2nd time NEXTBAND was called. This is absolutely not what we want. We'd like to have correct band rect(s) for landscape mode. Is there any solution for such condition in unidriver ? Or the only way is to write my own driver ?

The root cause of the problem is explained at http://www.bustrace.com/products/delayedwrite.htm. On this page there is also a little test tool that is able to reproduce the problem. The solution is to write a filter driver that prevents IO larger than 128Kb to reach the drive.

I thought I could use the hadrware timer to genearte interrupt every time and write a device driver to handle it. However, my first question is: Is it possible to accomplish it? I mean, is it possible to get such a high frequency reliable under Windows? will not my interrupts be delayed by task switching, other interrupts etc. Is it possible to disable task switching etc for a short time?

 - SPTI rejects valid requests I'm witing some low level CD access stuff (writing DAO in RAW mode and things). I'm mainly using SPTI, cos I'm developing under XP. The problem I'm having is that a number of calls are failing for no apparent reason. These calls work perfectly when I use ASPI as the transport (I choose to use ASPI or SPTI when my base level object is initialised - all the CDB construction and so on are in higher levels and identical). The 2 calls which I'm seeing give problems are Read TOC (ATIP) and ReadCD (with a -ve LBA). I've looked at the CDB and in both cases it is identical. The errors I'm seeing are Address out of Range (for Read CD) and 'invalid Operation for this track' for the ATIP reading. I cannot believe that something in Windows is doing this. But on the other hand, nor can I see anyting odd I'm doing with these particular functions. The Object proper is quite happy to use dozens of other functions (including ReadToc with other parameters!) and happily writes audio cds and DVDs and reads the same. Just these few functions ... Can ayone throw light on this? Iain Tag: USB Modem device Tag: 40839

 - Map interface index from the IP Helper API to an intermediate driver miniport instance. Hi! Is there any way for an intermediate driver to find out (in either ProtocolBindAdapter or MiniportInitialize) what interface index (IP Helper API) it will get. In userspace I keep track of adapter by their iphlp index and I would like to make a call down an intermediate driver with that index instead of the name of the adapter. It would be awesome if each of my miniports instances could figure out that index on their own. Cheers! Tag: USB Modem device Tag: 40836

Called by the UPS service, I get here 180 Does this mean that I have to wait 180ms before issueing the output to the UPS to shut down Does this mean that I have to issue the output 180ms long It CANNOT mean that the UPS has to turn off 180ms after issuing the output because XP has no even begun to shut down I assume this value is in seconds. 180s seems to be an appropriate value for shutting down XP Thanks for your help Tag: USB Modem device Tag: 40819

 - OID problem Hi, I am developing a protocol driver. There I need to define my own WLAN OIDs. How it can be done. I have a driver developer manual from a chipset manufacturer. that chipset developer is providing some of his own OIDs. I am on Windows 2000. thought chipset developer provides his OID header files but as of now i don't have those. so thought if it is possible to write own OIDs. e.g. one of the OID provided by chipset manufacturer is OID_CURRENT_BSSID. I have some info from Driver Developement Manual for miniport drivers. Is there any way by which i can define these OID. regards, Puneet Tag: USB Modem device Tag: 40813

 - How can I lock user memory at DISPATCH_LEVEL? Hi My driver has to do lots of Scatter Gather List DMA operations. This used to be ok at PASSIVE_LEVEL, but it becomes a problem when I try to use a system queue and call DMA operation in my StartIo routine. Before I can start DMA operation, I need call IoAllocateMdl() to build MDL for the user memory and call MmProbeAndLockPaged() to lock the user memory into the physical pages. According to DDK document, MmProbeAndLockPages() function can be called at DISPATCH_LEVEL ONLY when the memory is not pagable, but I have no way to guarranttee that the user memory is nonpagable, right Is there anyway I can get around this Thanks zhong Tag: USB Modem device Tag: 40799

 - multiple virtual COM port support over USB I have a WinCE device that is able to connect to the PC via Active Sync over USB. It can also connect as a modem(but not at the same time). The drivers on the PC side for either of these expose a virtual COM port on the PC. I want to change my WinCE device side driver to add support for one more virtual COM port over the same USB connection. I have changed my device side descriptor to say it has two interfaces, but I'm having trouble enumerating two ports. Do the PC side drivers (wceusbsh.sys or usbser.sys) support enumerating multiple interfaces Thanks for your hel Tag: USB Modem device Tag: 40786

 - Problem using KeQuerySystemTime My goal is to inject a job id into a PS header using WMARKPS compiled in kernel-mode (for NT4.0). My development environment is WinXP Professional, VC++6.0, Windows DDK 2600.1106. 1.. Using the 'DDK checked' shortcut (on the start menu): 1.. I typed "set WINNT_40=1" 2.. After moving to " C:\DDK\WINDDK\2600.1106\src\print\oemdll\watermark_NT", I typed "build -cef". (I copied the watermark folder to watermark_nt, and modified the sources file so that watermarkps.dll would be compiled in kernel-mode). 3.. At this point I am able to install and use the NT version of WMARKUI and WMARKPS on an NT4.0 system. 2.. From this point I want to simply inject a PS comment that consists of a JOBID generated from the system time. 1.. In the PSCommand method of Command.cpp in WMARKPS I want to use KeQuerySystemTime(), but when I compile, KeQuerySystemTime() causes an undeclared identifier error. 2.. If I "#include <ntddk.h>" (or wdm.h), the compiler says that it can' t find the header files. 3.. If I "#include < C:\DDK\WINDDK\2600.1106\inc\wxp\ntddk.h>", the compiler gives me a bunch of redefinition errors. 4.. If I "#include < C:\DDK\NTDDK\inc\ntddk.h>", the compiler again gives me a bunch of redefinition errors. How can I get methods defined in NTDDK.H to compile? Thank you, Mike Tag: USB Modem device Tag: 40771

 - IP Address Assignement Problem on WinME- A starnge one. Hi, I am facing a strange problem on WinME. I am connecting two USB Network Devices on My system running WinME. I assign x.y.z.1 address to first card (say Card1) and x.y.z.2 to second card (say Card2). Ping works on both the cards. Now I remove both the cards and connect card2 first. What I see is that the system has assigned x.y.z.1 address to this card2 and if I connect Card1 now the system assigns x.y.z.2 address to Card1. (Actually we would expect the system to assign x.y.z.1 addres to Card1 and x.y.z.2 to card2) Why the system is behaving this way? Is it any known issue on WInME or is there anything that I am missing in my driver or in INF file. Please help me in sorting out this issue. thanking you in advance. regards, Nazim Tag: USB Modem device Tag: 40770

 - CARDBUS-Card incorrectly enumerated as MTD-0002 Memory card I tried to install a CARDBUS-Card in my Toshiba Satellite Pro 4320, with Win2K SP4 on it. When I inserted the card, it was recognized as the PCMCIA MTD-0002 memory card. All tries to install the correct driver failed. On other notebooks or desktops the card is recognized correctly. I also tried to update the bios, but without solving the MTD-0002-problem. The used cardbus controller is a Toshiba ToPIC100 Thank you for your efforts greeting Tag: USB Modem device Tag: 40769

 - Microsoft Printer Language Monitor Hello All: The Story so far ---------------- I want to compress a PCL output file via a standard UNIDRV based printer driver in w2k. I need to do this so that a compressed PCL file is read by another custom tool which will extract and interpret the PCL Data. To do this, I need a language monitor with my unidrv based printer driver. According to my picture, The story goes that the pcl data is received in the language monitor from the print processor. The language monitor will compress and send the data to microsoft's own port monitor via the FILE port and the file is saved and compressed. Problem: -------- I have compiled Microsoft's own sample of a language monitor, namely the pjlmon package but I only could do this if I change the following: 1: There is a case statement with a syntax error using a ';' instead of ':' 2: The assignments to the function pointer types mismatch so I had to create wrappers which match those in the MONITOREX structure used in the sample. I installed microsoft's language monitor successfully after some hassle but I still have more issues. Namely: 1: I had to remove references to critical sections everywhere. 2: I had to remove a validation UpdateTimeoutsFromRegistry in the InitializePrintMonitor. My problem is that my WritePort in the sample is not being called. I have included some file output traces to check for this. I also see that in MSDN, docs state that InitializePrintMonitor2 is to be used for language monitors. It is not the case in MS's own sample. Does anyone have experience on MS Language Monitors who can shed a light upon my problem please? Thanks and Best Regards Duncan Camilleri Tag: USB Modem device Tag: 40767

 - DiskPerf Crashes. Hi Guys I am using Win XP Pro SP1 for developing a simple device driver. As i am a beginner i wanted to test the DIskperf.sys provided in the DDK kit. I have two hard disks connected in my system say disk1 and disk2 disk2 is the secondary slave. so i install the diskperf.sys in disk2 .. as addfilter /device \disk2 /add diskperf.sys after that i restart the system then i can see that my disk2 is not at all recognized. To solve the problem i go to Device Manager,uninstall Disk2 and again do a scan for plug and play hardware. This seems to be a recurring problem. Any help is awaited...

 - DbgPrint in Irql=2 I had a debug print in the Irql = DISPATCH_LEVEL when I acquired spinlock. There was bug check "invalid address access at higher Irql, Irql = 2". I removed the print and I had no problem. Is it DbgPrint should not be called after acquiring Spinlock(before releasing lock) or my problem is just hidden. I know we should release spinlock as soon as possible but I just had print (only for testing). Is it bug to have print in spinlock. Tag: USB Modem device Tag: 40760

 - The USBView in 2003 DDK can not work well on Windows 2k. The new version of USBview can not work well on Windows 2k. 1.When build the usbview "using obsolete header file usbioctl.h". 2.Use it in Windows 2000 and Windows XP, Usbview can not show all the USB device. 3.I have debug into it. It failed in "IOCTL_USB_GET_NODE_CONNECTION_INFORMATION_EX"(It is "IOCTL_USB_GET_NODE_CONNECTION_INFORMATION" in old version.). Did the new version of USBView can only work on Windows XP (with all the needed update)? Is there any way to make the new USBView can work on other system? Tag: USB Modem device Tag: 40756

 - working with multiple OS versions Hi All, The question is at the end. I have a PCI device + driver, which has to work on both Win-NT and Win-2K. I have 2 Drivers : A WDM driver for Win2K, and a Non-WDM driver for Win-NT. So, far everything is great. The 2 drivers has the axact same interface from the application point of view. The only difference is in the "CreateFile() method". So, naturally, I want to have one DLL for both drivers, and do the CreateFile() according to the runtime OS version. This works also very good. Here comes the problem : Up until now, I compiled the DLL on Win-2K, and ran it under both OS. Now, I want to compile this DLL, under Win-NT (I am not expecting to run this DLL on win-2K). I am expecting to have one code though. Now the following line does not compile !!!! "include <initGuid.h> The file axists, but I get some funny compilation error. Here I do not care for the GUID (I CreateFile() by the good old NT method), so I delete this line and everything works. Remember that I am expecting to have one code for the DLL. I want to do something like: #if (WINVER > 0x0400) "include <initGuid.h> #endif But for some reason, this does not work: On my Win-2K compilation machine, WINVER is also defined to be 0x0400. *************************** So here comes the question : How do I figgure out during compilation, which OS version I am compiling on ? I want to use some compiler variable. Thanks Maurice Tag: USB Modem device Tag: 40754

 - KSPROPERTY_MEDIASEEKING_FORMATS / ksproxy!CKsProxy:QueryMediaSeekingFormats Hi All, In my continuing quest to implement IMediaSeeking in a stream class minidriver, it seems that the ksproxy itself (and not a component aggregated by it) will ask you which seeking formats you support (via KSPROPERTY_MEDIASEEKING_FORMATS), if you support KSPROPSETID_MediaSeeking on the device (and not on the pin/stream). However, I don't know where to stick the answer. The DDK docs on this are sketchy to say the least. I'm getting pSrb->CommandData.PropertyInfo->PropertyInputSize = 18 (= sizeof(KSPROPERTY)) pSrb->CommandData.PropertyInfo->PropertyOutputSize = 0 I've tried returning STATUS_BUFFER_TOO_SMALL (as per SRB_GET_DATA_INTERSECTION) and/or STATUS_BUFFER_OVERFLOW, but when I do that, I don't get any further requests. So, I tried returning STATUS_SUCCESS, but that resulted in ksproxy reading from address 00000004. Has anyone ever done anything with this? Max P? thanks for ANY help, Matt Tag: USB Modem device Tag: 40753

Hi,

We have a USB modem device, which is acually a GSM/GPRS phone. The GSM/GPRS
part may need the PIN code for the SIM card in order to make calls. Se when
the initialization command has been sent, we must ask the device if it it
needs the PIN, and present a dialog if it does.

How can we accomplish this?

Please direct me to relevant documentation or newsgroup.

Leo Havmøller.
