    - Problems building vxds with Me ddk ... Hi There is a way to accomplish this using DDK's Me build environment and Visual C++ 2003 ? When I open the build environment it says: Installation of MSVC not detected!!! ERROR: MSDEVDIR Environment variable not recognized. Microsoft Visual C++ 6.0 must be installed.

    - Full Duplex hi! I am writing a driver for a thernet controller which supports 100/10 Mbps Ful duplex operation.. at one place in the documentation for the MiniportqueryInformation I read that WinCE doesn't support full duplex.. At many other places there are statments like "if the miniport driver is full duplex".... Now I am not able to understand clewarly that whether or not I can take th full duplex adavantage of my NIC through a miniport driver writtten for WinCE. Can anyone please clarify me on this. regards -Nitin Tag: How to get USB device name Tag: 47432

    - DeviceIoControl returning ERROR_FILE_NOT_FOUND Hi I have more than one IOCTL in my driver but one of them is giving error ERROR_FILE_NOT_FOUND when I call DeviceIoControl. The IOCTL is implemented in the driver, and was working ... But I have changed only the check about the buffer size passed to the driver and have put a critical session protect by a spin lock into the IOCTL processing and only for this IOCTL the error is ERROR_FILE_NOT_FOUND. the others IOCTL are working fine. any ideas ?

    - Print driver: Removing PaperSize definitions Hi, I noticed a problem with the size of a vendor specified paper size in my Unidriver GPD file. I fixed it, but it appears that the old definition still exists. I did a search on my XP registry and found the old name under several entries, one being HKLM\SYSTEM\CurrentControlSet\Control\Print\Forms. I think this is causing me problems because the only way to get the fixed version to appear in the driver "properties" section is to give it a different name. Is the only way to remove the paper size definition to manually delete it from the registry? Tag: How to get USB device name Tag: 47394

    - ImageProcessing and banding... Hello all; (Win2K UNIDRV OEMDLL) I'm doing a custom halftone (downconversion from 8BPP to 1BPP) in ImageProcessing, and handing the bitmap back to UNIDRV for output to spooler. With a res of (203(X) x 508(Y)), when a page is rendered in 2 bands (i.e., a 1728 wide x 5588 Letter size page), the data output is 2 x the height of the first band, NOT the sum of band heights. That is: (from pBitmapInfoHeader->biHeight) Band 1: 2800 lines high Band 2: 2788 lines high. Data out = 5600 lines, NOT 5588. Obviously, the last 12 lines are garbage data. I'm processing the data and returning it in the supplied bitmap area, and returning *ppbResult = pSrcBitmap; for each band. Should I handle banded (repeated) calls to ImageProcessing *differently* from single-band page calls? If all else fails, I can write to the spooler directly, but I'd rather not. Thanks! -- J.C.

    - Does IOCTL_USB_GET_NODE_INFORMATION trigger USB bus enumeration? Does anybody knows how ecxatly IOCTL_USB_GET_NODE_INFORMATION and IOCTL_USB_GET_NODE_CONNECTION_NAME calls work? I am developing a USB device driver for a USB device. And for the testing reason I want to have some PC application wich can show me if my device was succesfully enumerated. But I donâ??t want to force the enumeration by this applications. The UsbView example from DDK looks useful for my purpose, but unfortunately I canâ??t find any information about IOCTL_USB_* calls.

    - How to write and read from a I/O address directly in VC++? Hi My friends, My company made a very old motor controller, it's a ISA card. It works under DOS now. Our customer and my boss want it can be worked on Windows operating system(XP or NT) I checked its source code( for DOS 6.22), most of controls are done by writing and reading from several I/O addresses. As I know in windows, I can not access low level I/O directly. Would you like to tell me how to do it? I think i need to write a driver for it. If you could give me some information on how to write device driver, I will really appreciate it. I 'm a VC++ programmer, but I never wrote driver before. If you'd like to write to me, you email address is lchang@andec.ca Thanks ahead. Larry Tag: How to get USB device name Tag: 47387

    - SATA disk drives - IOCTL_ATA_PASS_THROUGH support I've been looking for a third party SATA controller that supports IOCTL_ATA_PASS_THROUGH, but I've had no luck. Does anyone know of a controller that supports this? From what I've seen, third party SATA controllers (Adaptec, Promise) are implementing there miniport drivers as SCSI miniport drivers, so IOCTL_SCSI_PASS_THROUGH is supported, but not IOCTL_ATA_PASS_THROUGH. This makes something as simple as sending an Identify command through the pass through interface impossible (?). Also, does anyone know if the Intel ICH5 chipset supports the IOCTL_ATA_PASS_THROUGH for SATA devices? Any feedback would be greatly appreciated.

    - Device to be opened from a DOS program (i.e., NTVDM) Hello, currently, I'm trying to modify a driver to be able to be opened from a legacy DOS program (compiled with Turbo Pascal, if this matters). Anyway, I can't find a way to do it. There is a Symbolic Link created, and opening it from a Win32 application works like a charm. Anyway, if the DOS based program opens the device (with a call to LongOpenFile('\\.\giveio', F, fmReadOnly)), the call always fails. Anyway, I can see from the debugger that the device is opened and immediately closed. And: Yes, I always return STATUS_SUCESS in response to IRP_MJ_CREATE: Irp->IoStatus.Information = 0; Irp->IoStatus.Status = STATUS_SUCCESS; IoCompleteRequest(Irp, IO_NO_INCREMENT); return STATUS_SUCCESS; There is no other return path. I don't have a clue what to do. I thought that the symbolic link might need to be created somewhere else than in \DosDevices\, but since the IRP_MJ_CREATE routine is called (as well as the IRP_MJ_CLOSE routine), I don't know where to search. I already had a look at how LPTx are created, as they are accessible to NTVDM programs, too, but I could not find a hint what I am doing wrong. Any ideas? Regards, Spiro. -- Spiro R.

    - How to force Windows to ignore USB port difference? Hi, I search all along a method that to force Windows ignore USB port difference, because when my usb device is inserted another port Windows XP will guide to install its driver. In general, it's OK and friendly, but in my case user will have no chance to install it. So automatically setup usb device is must. One method is that to add a serial number in device itself. It's said that it's OK. But I cannot demand device provider do such. Another one maybe is to let Windows XP to ignore USB port difference. But how can I do it?

    - ISA-Device and PnP-Manager Hello, I have a ISA-LCD device and the PnP Manager starts the HW-Wizard. So far so good. When I give the Wizard my driver for this device, only the memory resource (not the port I/O and interrupt resources) are installed. When I cancel the PnP HW-Wizard and install my driver with system->Add Hardware Wizard the resources are all available. But after the next boot the PnP Manager finds a new device (other display) and starts the HW-Wizard and my driver has the yellow exclamation mark. When I uninstall the driver rudiment "other display", my driver gets all resources and the exclamation mark is gone. How can supress the start of the PnP HW-Wizard for this device???

    - Windows XP Spooler Hi Under Windows NT4.0 the spooler would load any language/port monitors immediately when the spooler was started. Under Window XP Pro SP1 the spooler can take up to 2 mins before it loads them. This is circumvented as soon you access the print manager or send data to the printer. Is there a way to get this to behave in the same fashion as NT, i.e. load the monitors as soom as I start the spooler. Thanks Sandy Tag: How to get USB device name Tag: 47346

I'd like to know what I have to do to be able to access registers of a chip like the Winbond W83627THF LPC I/O http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/627hf.pdf Do I need the DDK, is it possible to access the chip via windows-api? How do I access a certain register, if I know the hex address according to the manual? With the microcontrollers I programmed I just had to read from this adress, like: #define LEDS 0xFF04; if(LEDS==0x01){..} Maybe someone has got a hint or links to docs I should read.

    - UMSS for win 98 Hi,All: I used Microsoft release UMSS source code to develop our USB mass storage driver for windows 98. I found that When AEP_DEVICE_INQUIRY is received, I create IOP and submit ILB request to call my WDM driver. Normally the ILB request will wait until my calldown complete routine is complete, then I free the IOP. But sometimes the ILB request will complete after calling my WDM driver(my WDM driver don't issus complete). When my calldown complete routine is complete, the system hang. Because the IOP is free. Does Anyone know what happen? Gil Source code: ((PISP)&IOPCreateISP)->ISP_func = ISP_CREATE_IOP; IOPCreateISP.ISP_IOP_size = IOPLength; IOPCreateISP.ISP_delta_to_ior = (ULONG)&(((pIOP)0L)->IOP_ior); IOPCreateISP.ISP_i_c_flags = ISP_M_FL_MUST_SUCCEED; // Call IOS ILBService(&IOPCreateISP); // // Build our I/O request // // Call IOS to fill in SG descriptors, etc. ILBCriteria(Iop); // Submit request to IOS ILBRequest(Iop, Dcb); // Free our IOP ((PISP)&AllocISP)->ISP_func = ISP_DEALLOC_MEM; ((PISP_mem_dealloc)&AllocISP)->ISP_mem_ptr_da = (ULONG)Iop; ((ILB_internal_request_func)(UMSSPDR_Ilb.ILB_service_rtn))((PISP)&AllocISP); Tag: How to get USB device name Tag: 47315

    - SetPrinterData Dears, I'm building cosumized dll using unidrv model (oemdll example).

I'm faceing a problem I tried to use SetPrinterData, or EngSetPrinterData, both return code 5, i guess this means access violation. the code is: dwResult = SetPrinterData(pdev->hPrinter, STDSTR_FONTDATASIZE, REG_DWORD, (PBYTE) &FontSize, sizeof(DWORD)); where FontSize is a DWORD and STDSTR_FONTDATASIZE is defined as follows: #define STDSTR_FONTDATASIZE TEXT("FontDataSize") hPrinter is stored when the driver received the EnablePDEV call, and it worked in GetPrinterData.

    - windows = realtime? Hello, I have posted similar topic some weeks ago and now I want to discuss it further. I'm searching for operating system to meet real-time constraints. I know that windows is not true real time system, but I have found some papers complaining that Windows NT can be used as real time system. It complains that total interrupt latency of NT is about 30 microseconds. That sounds good for me. I found nothing about Win 2000 and XP interrupt latency. Maybe someone knows? I think if I write my apps in Ring0 as kernel mode drivers, then I will have latency as system interrupt latency. So why Windows cant be used as real-time system? Maybe someone have good ideas or links about that. I found it very interesting topic. I have searched through internet and found lots of add-on for linux kernels, but they can guarantee about 30 microseconds latency. Developers complain that these add-ons is real time. So why windows with 30 us latency can't be real time? Thank you for any thoughts. alpha Tag: How to get USB device name Tag: 47307

There is a MaximumSize arg to ZwCreateSection, and a flag SECTION_EXTEND_SIZE. But how do I guess at a size, then if turns out I did not need so much memory, how do I shrink it down?

    - SilentInstall Hi We have developped a device driver stack that "mounts" removable storage. When a new volume is detected by PnP manager, the system ask for one of our drivers (the one actually creating the disk objects), even is this driver has already been installed in the system. We have then to provide the path to this driver file, and this is somewhat annoying. We want to avoid this behavior. In our DispatchPnp routines, we set the SilentInstall capabilities this way: case IRP_MN_QUERY_CAPABILITIES: { PDEVICE_CAPABILITIES capabilities; capabilities = irpSp->Parameters.DeviceCapabilities.Capabilities; capabilities->SilentInstall = 1; ... ntStatus = STATUS_SUCCESS; break; } Our drivers are not digitally signed and won't be for a long time.

GENERIC_READ : GENERIC_READ | GENERIC_WRITE, &object_attributes, &IoStatus, NULL, FILE_ATTRIBUTE_NORMAL, FILE_SHARE_READ|FILE_SHARE_WRITE, FILE_OPEN, FILE_NON_DIRECTORY_FILE | FILE_RANDOM_ACCESS | FILE_NO_INTERMEDIATE_BUFFERING | FILE_SYNCHRONOUS_IO_NONALERT, NULL, 0 ); Unfortunately,It doesn't work.why? how to deal with it? Thank you in advance. Steve Tag: How to get USB device name Tag: 47251

    - SetupDiGetDeviceRegistryProperty - Doc error? OS: XP without service packs. SetupDiGetDeviceRegistryProperty being called from the class coinstaller DLL does not support the NULL PropertyBuffer + the zero PropertyBufferSize, contrary to what is stated in the documentation: "Supplies a pointer to a buffer to receive the property being retrieved. If set to NULL, with PropertyBufferSize set to zero, the function just returns a value for RequiredSize." If being called with a zero PropertyBufferSize - it returns ERROR_INSUFFICIENT_BUFFER. If being called with a nonzero PropertyBufferSize and NULL PropertyBuffer - it returns ERROR_INVALID_DATA. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim@storagecraft.com http://www.storagecraft.com Tag: How to get USB device name Tag: 47237

    - WHQL: can Microsoft sign the filter driver? Can Microsoft sign the filter driver + its class coinstaller DLL for the CD/DVD-ROM stack, which inserts itself between IMAPI and the storage port? The class coinstaller is needed with the sole purpose of patching the LowerFilters value for the newly arrived hot-plug (SBP-2 or USB) drives, and injecting our filter below IMAPI, so that IMAPI's SCSI traffic will also be monitored. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim@storagecraft.com http://www.storagecraft.com Tag: How to get USB device name Tag: 47231

    - Writing kernel API functions Can anyone direct me to documentation on how to write, or whether it is feasible to consider writing, a kernel API function that permits a kenerl component, such as a device or filter driver, to initiate communication with a user-space service? I have a need to develop something like the Event Log API that is available for device drivers or the WMI interface. I know that these actually communicate with other kernel code, but I would really like to send information to a service, without requiring that the service issuing an IOCTL to the driver and waiting for a response. -ken Tag: How to get USB device name Tag: 47221

    - printer driver signing Hello, Does driver signing requires the driver to be associated with hardware device. For e.g:- If I have a printer driver which acts as a format convertor(lets say converts to .doc format), how can I get this driver signed? I feel it is possible to have computer policies which restrict installation of drivers which aren't digitally signed. So I would prefer to get them signed. Any insights here with the above case. This is for windows 2000/XP/2003. thanks vipin Tag: How to get USB device name Tag: 47220

    - decrypt WPA group key Hi, This probably isn't the best newsgroup for this question, but probably the ones knowing the answer can be found here :) During WPA group key handshake using TKIP I will recieve a key encrypted with RC4 I have used OpenSSL to decrypt and that works fine, but I would like to use CryptoAPI. This is how I have done it with OpenSSL void DecryptGTK(unsigned char *pIV, unsigned char *pKEK, unsigned char *pData, unsigned char *pRet) { unsigned char keys[32]; memcpy(keys, pIV, 16); memcpy(&keys[16], pKEK, 16); RC4_KEY key; RC4_set_key(&key,32, (const unsigned char *)&keys); unsigned char tempin[256]; /* Temporary input (discard) */ unsigned char tempout[256]; /* Temporary output (discard) */ RC4(&key, 256, tempin, tempout); /* Step 256 times */ RC4(&key,32,pData,pRet); } now I started to implement the CryptoAPI, but right now I can't make sense out of it. DWORD dwCryptoPasswordLength; DWORD dwDataValueLength; HKEY hKeyResult; HCRYPTPROV hCryptoProvider; HCRYPTKEY hCryptoKey; HCRYPTHASH hHash; if(!CryptAcquireContext( &hCryptoProvider, NULL, NULL, PROV_RSA_FULL, 0)) { printf("!CryptAcquireContext"); } if(!CryptCreateHash(hCryptoProvider, CALG_MD5, 0, 0, &hHash)) { printf("!CryptCreateHash"); } dwCryptoPasswordLength = 16; if(!CryptHashData(hHash, (LPBYTE)pKEK, dwCryptoPasswordLength, 0)) { printf("!CryptHashData"); } if(!CryptDeriveKey(hCryptoProvider, CALG_RC4, hHash, CRYPT_EXPORTABLE, &hCryptoKey)) { printf("!CryptDeriveKey"); } if(!CryptSetKeyParam(hCryptoKey, KP_IV, pIV, 0)) { printf("\nCryptSetKeyParam\n"); } dwDataValueLength = 32; DWORD dwBuff = 32; if(!CryptDecrypt(hCryptoKey, 0, TRUE, 0, pData, &dwDataValueLength)) { printf("!CryptDecrypt"); } any ideas how this should actually be solved? /thanks Tag: How to get USB device name Tag: 47219

    - Terminal server and windows 2000 Printer driver Hello, Can someone explain me this behaviour:- 1) Installed my printer driver on machine A locally on 2000 terminal server. 2) Connect to machine A from a 2000 professional machine "vipin" using remote desktop connection and login as USER1(this is in administrative groups) 3) Connect again to machine A from 2000 professional machine but with login USER2(Administrative group rights) Observation:- Each time I connect, I see a new printer getting created of the form printername\vipin\session0 printername\vipin\session1 .... and makes it the default for the session. Everytime I logoff the session, the correspomnding session instance gets deleted. It would have been fine if there were one session instance viewable in the session's printer folder, printer session instances of all the sessions to the Terminal server are visible. In addition there is a printer of the form "printername". These are viewable also when you log as a user on the Terminal server itself. So I installed the Microsoft drivers(one's that come with the operating system using Add Printer), I make connections, I don't see the behaviour. Can someone tell me whats causing this behaviour? thanks vipin Tag: How to get USB device name Tag: 47210

Hi,

I modified the Microsoft DDK sample USBView to enumerate all devices on the
USB. But now I need a device name to make a CreateFile() on each Device.
File names in the format "\\.\USB#Vid_04cc&Pid_1122#5&d3bcdf4&1&1#
{f18a0e88-c30c-11d0-8815-00a0c906bed8}" can I get only for external USB
hubs, but not for other devices.
How can I get these file names for my devices?

Thanks
Michael

SetupDiGetClassDevs for a particular class (storage or such) can help.

Also look in DEVCON sample.

a device name, in this case a device interface, implies a certain interface
to the driver. that interface is supported IOCTLs, read/write semantics,
etc. this means that even if you could generically get all the file names,
you will not be able to send the IOCTL you want to each one unless you know
specifically what the device is.
