    - USB BULK speed, driver hello, I am developing driver for CYPRESS USB2.0 FX2, EP2, BULK IN, My problem is that I must do BULK_READ within every melliSecond or even 500uS or less. Otherwise the data will losed between two BULK_READ, because the FIFO in CYPRESS FX2 is very small. How can I do that? Is it possible to let the Driver continuesly do BULK_READ, and fill an ring_buffer? time between 2 BULK_READ must be 1ms or less. thank you very much. william Tag: Watchdog in WinXP Tag: 29488

    - Where to start learning to program drivers I'm an applications developer and have been for 15 or so years. I'm finding it necessary in my job to work on drivers, including writing a brand new one from scratch. The only experience I have writing drivers is for the old MacOS where I could do whatever I wanted with no real kernel to speak of. With Windows it seems to be a very different story. Where should I begin when learning how to develop drivers for Windows. 9x and 2k/XP? ( I really don't care about NT 3/4 right now ). Are there any books that start from the basics and go from there? I don't need a "for dummies" book but I do need something that starts from the beginning and ends with most of what I need to know to write a fully functional driver. Thanks, Janik Tag: Watchdog in WinXP Tag: 29465

    - INF XP and 2000 1) How to have XP and 2000 use same INF file. I know we can use OS decorators in sections to keep one INF for both OS. But decorators like .NT, .x86 cannot separate XP from 2000. Is it .xp for XP sections and .NT for NT and 2000? I dont worry about 98 and ME. 2) Can we have different version sections for different OS in same INF. I want to use different class GUIDs for different OS. 3) What should be the classname for 1394 device driver (NOT Host controller driver). I tried 1394Test and chkinf raises error message 'obsolete or unknown class name'. Thanks for the comments. Tag: Watchdog in WinXP Tag: 29452

    - PageSize units inconsistancy? UniDrv and .NET We are developing an application that automatically prints pages based on data retrieved from a database. The data includes the printer name and the desired page size. Our printer doesn't support any standard page sizes. We've created our own printer driver based on UniDriver. The printing application can successfully select the desired printer. However, selecting the desired page size doesn't work. We're trying to select the page size using the PaperSize.PaperName property. Here's the C# code: // m_PrinterName is the name recognized by Windows // pageSizeName is the name of the page size matching that in the GPD file. // debug only - look at current default paper size. PaperSize psDefault = pd.DefaultPageSettings.PaperSize; // Create a PrintDocument PrintDocument pd = new PrintDocument(); // Use a standard print controller - to avoid the status/cancel dialog pd.PrintController = new StandardPrintController(); // Set the printer name (from the printer device object) // This name must match the installed Windows printer. pd.PrinterSettings.PrinterName = m_PrinterName; if( !pd.PrinterSettings.IsValid ) { // Log the error and then quit } foreach( PaperSize psize in pd.PrinterSettings.PaperSizes ) { if( psize.PaperName == pageSizeName ) { pd.DefaultPageSettings.PaperSize = ps; // select this one break; } } The interesting thing here is that the units for the sizes (width and height) are not consistant. For the particular test that I'm running I know that the paper size desired is the same as the default size for the printer. But when I look at the properties of the default paper size (psDefault above) and the selected size in the list (when psize.PaperName == pageSizeName ) they don't match: default selected kind: 0x103 0x94 width: 0xde4 = 3556 0x578 = 1400 height: 0x10de = 4318 0x6a4 = 1700 name: "custom" "14INX17IN" The size units for the default appear to be hundredths of centimeters, while the size units for the selected paper size are hundredths of inches. But using the selected paper size doesn't work (the page is too small). The driver seems to want the metric size. The documentation indicates that sizes should be hundredths of inches and that's the unit used in the rendering code. Any idea what's happening here? Thanks, Tom Tag: Watchdog in WinXP Tag: 29418

    - Differences between inf installation in w98/ME and 2000/XP Hi, Thanks everyone who helped me with some problems some time ago. I built a wizard for installing modem - based on inf files included by manufacturer. It runs properly on 2000/XP, but fails on w98/me. The basic schema is like this: - InstallHInfSection (copies files) - optionally remove "unknown devices" - i.e. modems not properly installed (SetupDiGetClassDevsEx, CM_Get_DevNode_Status_Ex, SetupDiCallClassInstaller - with remove flag) - reenumerate dev node - for root - scans system for new devices This schema installs modem properly on 2000/XP, but fails on W98/ME Last step sometimes runs scanning, sometimes not, and even if it starts the scan, the new hardware wizard shows up and asks for the path to inf file. Could you please help with that? -- K. Support bacteria -- it's the only culture some people have! Tag: Watchdog in WinXP Tag: 29415

    - WDM driver instalation I have simple audio WDM driver that I install it with an INF file. I specify in my INF file StartType of 3 wich means SERVICE_DEMAND_START. After instalation I get these registry keys in HKLM\System\CurrentControlSet\Service\MyAudioWMD Start 3 Type 1 ErrorControl 1 The problem is when I restart my computer, my driver is loaded at system startup not as it is specified in Start option at demand start. When I set Start type to SERVICE_DISABLED (0x4) the driver is not loaded at system startup, which is the expected behaviour. Is there anybody that experienced this problem ? I suppose that PnP manager is involved at sometime or may be LoadOrder key in registry, but how can I control and instruct them ? The [Vesrion] section of my INF file is : [Version] Signature=$Windows NT$ Provider=%Provider% Class = Media ClassGuid = {4d36e96c-e325-11ce-bfc1-08002be10318} DriverVer=07/28/2003,5,0,1636,1 and the service section is : [DriverService] DisplayName = "WDM Audio driver" ServiceType=1 StartType=3 ErrorControl=1 ServiceBinary=%10%\system32\drivers\wdmaudio.sys Thanks Eugene Tag: Watchdog in WinXP Tag: 29409

    - Blocking Setup API call (win2k) - for MS Hi, I use a utility which is using setup API's to enable/disable my virtual network adapter. The code simply locates the device and using DIF_PROPERTYCHANGE along with SetupDiCallClassInstaller enable/disable the device. Sometimes after system resume from suspend, when this utilty call SetupDiCallClassInstaller it never returns from that call. Setup API log file implies that the thread is executing the default installer code. If I attach with debugger to the blocked process I could only see that the stuck includes calls to SetupDiCallClassInstaller (and subsequent calls to function one of the RPC dlls - I think rpcrt4) Thnaks for the help.

    - USB interrupt pipe data loss on Win2000 I wrote a USB driver under Windows 2000. I retrieve data from a interrupt pipe. The interval defined in my device is 1ms. The datarate from my device is 384kbps. However, I always loss data on PC. If I make my device send data at 200kbps. I can receive data from PC properly, no data loss. The most strange thing is, when I used my driver on Windows XP, it actually can recieve data properly at 384kbps. Anybody can tell me that, why my driver can only work on winxp.

    - Writing a RAS device driver Ok here's a fairly broad question... I need to write a driver (I guess) for RAS (or TAPI?) that makes itself available as a device that RAS can use to connect with. Something like PPPoE (but not PPPoE). This needs to work for Win9x and NT/2k/XP. It needs to communicate via a serial port or USB. I've spent lots of time digging though the DDKs and MSDN but can't find a straight answer. Can someone tell me what this thing that I need to write is called and where I might find sample code of some sort? In some cases all my stuff would need to do is act as an intermediaty between RAS and another RAS device (of any type). Is this possible? Thanks, Janik Tag: Watchdog in WinXP Tag: 29377

    - Restricting page sizes in WIA Microdriver Hello, I'm developing a WIA Microdriver and I need a way to restrict the page sizes that are available through the WIA UI. The device I'm developing for only supports a few page sizes and if I return "not supported" for the other available page sizes, the current application usually gives some kind of scan failed message. I had a similar problem with Resolutions, but I discovered that a registry key could be created in the DeviceData section of the driver that would restrict the available Resolutions. I have not been able to find a similar registry key for page size though. Any help would be appreciated. Thanks, Danny Tag: Watchdog in WinXP Tag: 29371

    - How to set the parallel port into ECP mode? We have found that the parallel port seems to work exclusively in compatible mode even so the pinter is capable of ECP mode. It seems that every time the PC is initiating the parallel port it has to agree on a mode to be in with but it is not making any efforts to change into ECP mode. Can anyone tell me how to convince the PC (driver) to switch the PC parallel chip into ECP mode. Just setting the BIOS into ECP is not good enough. Do we have to write our own LPT low level driver? Can Microsoft help us to do this? Is there a hidden setting in the Registry to enforce ECP mode vs. compatible mode? All help and ideas are very much appreciated in this regard.

    - Raw Input Thread Where exactly does the Raw Input Thread recieve its HID mouse input from? (is it from mouclass or hidclass or mouclass + hidclass?)

Slide 24 of "How to Use Input Device Support in Windows XP" WinHEC 2001 (http://www.microsoft.com/whdc/winhec/presents2001/InputDr ivers.ppt) The slide shows a diagram that I am somewhat confused about. In the diagram the Raw Input Thread is connected to the mouclass, hidclass, and hidparse drivers. Does mouse input go through each of these routes to the Raw Thread, or would the hidclass driver redirect the input to the mouhid/mouclass drivers? Also, what does the hidparse.sys driver do?

    - What is the puprose of NdisMIndicateStatusComplete? Hello All! Does someone of NDIS developer know, what is the purpose of the NdisMIndicateStatusComplete function (and corresponding ProtocolStatusComplete callback in protocol/IM drivers)? All sources of NIC drivers I have ever seen always call NdisMIndicateStatusComplete right after NdisMIndicateStatus, so there is no timing ("to optimize when network load is high" as DDK states). In contrast to this, most drivers call NdisMEthIndicateReceiveComplete after some sequential calls of NdisMEthIndicateReceive. Both ProtocolStatus and ProtocolStatusComplete run at IRQL_DISPATCH (or IRQL_PASSIVE for deserialized callers), which means the existance of ProtocolStatusComplete can not be ideologically protected as it does for ProtocolReceiveComplete ("ProtocolReceive should run as fast as possible, ProtocolReceiveComplete gives a chance to process anything that was deferred during ProtocolReceive"). There is another catch: if NDIS (or at least some too wise protocol) suppose ProtocolStatusComplete will always be called after ProtocolStatus, a deadlock may occur in following situation: 0. suppose intermediate driver is not currently sleeping 1. ProtocolStatus is called "to indicate the start of status change". IM driver, as DDK requires, translates this status to upper protocols with NdisMIndicateStatus. 2. ProtocolPnPHandler is called with NetEvent code NetEventSetPower to transition to low power state 3. ProtocolStatusComplete is called "to indicate the end of status change". At that point, IM driver has already disabled interal operations because of SetPower do D3 (e.g. set PTDeviceState to D3, as Microsoft's PASSTHRU sample driver does). That means IM driver wont translate this to upper protocols, e.g. no NdisMIndicateStatusComplete will be called. If upper protocol relates on ProtocolStatus/ProtocolStatusComplete are in sequence - it will deadlock or malfunction somehow. In other words, both NdisMIndicateStatusComplete function and ProtocolStatusComplete callback are redundant and error prone. So, why on the earth are they remaining in the NDIS for 5 generations already? Knowledgable person' answer is preferred. Thanks in advance, Duh Pohmelja. Tag: Watchdog in WinXP Tag: 29264

    - 1394 Help! Hi, I'm starting device driver programming on 1394 bus, which is better to start with: - DDK for WinXP (1394diag, win1394....) - a third part generic device driver / API Any suggestions will be appreciated!!!

    - A question about PM events in NDIS IM. Hi, All! Does anybody know, is it true that PM/PnP/Init events in the protocol part of the NDIS intermediate filter driver are serialized (I'm not asking about events on the miniport part, only the protocol). In other words, could I be sure, that nothing of following happens: - There would be no ProtocolUnbindAdapter in the context of ProtocolBindAdapter (say, just after we have opened the adapter with NdisOpenAdapter, user unplugs the card - syrprise removal is treat as ProtocolUnbindAdapter AFAIK) - There would be no PM Event (NetEventSetPower) in context of ProtocolBindAdapter. IMHO, that is almost impossible - system falls asleep right after card was pluged. - There would be no PnP event (NetEventQueryRemoveDevice) in context of ProtocolBindAdapter. -etc... The base of this concern were: 1. PnPevent/PtBindAdapter/PtUnbindAdapter are processed at the IRQL_PASSIVE_LEVEL, so they may be preempted or interrupted. 2. Walter Oney's book describes that Power manager and PM manager have two distinct queues for PNP and PM IRP's, so they can preempt each other. Thanks in advance... Tag: Watchdog in WinXP Tag: 29236

    - Shared Interrupt Problem. Hi, I've loaded a partial checked build of Windows 2000 SP4 and the following seems unusual and might explain why the other devices with whom I share the interrupt stops responding. When loading the driver: EsccPci - DefaultPnpHandler: 0x9 (IRP_MN_QUERY_CAPABILITIES) EsccPci - HandleQueryDeviceRelations (PDO): 00000000 EXWORKER: Work item deadlock detected, creating type 1 worker thread EXWORKER: Created dynamic thread type 1, 0 total When unloading the driver: ****** Unloaded driver (EsccPci) EXWORKER: Dynamic type 1 thread no longer needed, terminating. Is this normal and if not, what is the cause? More detail about: "EsccPci - HandleQueryDeviceRelations (PDO): 00000000" The 00000000: Type, which is BusRelations The query is received as a PDO so I just "ignore" the IRP. NTSTATUS IgnoreIrp(PIRP Irp) { NTSTATUS Status = Irp->IoStatus.Status; IoCompleteRequest(Irp, IO_NO_INCREMENT); return Status; } The devices on the same interrupt 1. EsccPci - mine 2. 3Com NIC (3C900 - COMBO) 3. Intel 82371 AB/EB PCI to USB Universal Host Controller 4. Nvidia Riva TNT2 Model 64 Best regards Kobus Tag: Watchdog in WinXP Tag: 29235

    - DirectX 9 REF Rasterizer DDK Hi, Is the DirectX 9 DDK available for download somewhere? I could only find the DirectX 7 DDK. Is there are reason why the DirectX 9 DDK isn't on the Microsoft website? I would like to know how to create my own device, so the REF source code would be ideal. Also detailed information about IDirect3D9::RegisterSoftwareDevice could be sufficient. If anyone knows where to find these or could mail them to me that would be awesome: nicolas@capens.net. Kind regards, Nicolas Capens Tag: Watchdog in WinXP Tag: 29216

    - IoGetRemainingStackSize at dispatch? Greetings all, Why IoGetRemainingStackSize can not be called at dispatch irql? How can I know remaining stack size when I'm called at dispatch (in NDIS miniport etc)? And generally, can stack overflow in kernel mode pass undetected, or it always will bluescreen. -- Best regards, -PA Tag: Watchdog in WinXP Tag: 29215

Hi,

I want to know if there are any ways to tweak the Windows
Watchdog registers/values.

One of our Driver functions takes up more than 15seconds
(WAtchdog timer value), to complete its operation. And
hence the Watchdog fires and the system bugchecks with
THREAD_STRUCK_IN_DEVICE_DRIVER.

As I cannot reduce the execution time in my driver, I
want to know, if there are any interfaces to tweak
watchdog registers or parameters if watchdog is emulated
in software.

Regards,
ashok.
