    - Hiding device entry Hi all I want to hide my device entry under device manager in Windows XP . I came across a post which said when we set the DEVNODE status flag to DN_NO_SHOW_IN_DM we can acheive this. But the configuration manager part has API calls only to get the status of the devnode. Does anyone know how to set this flag. Is there any other means to hide device entry. My driver is not a filter driver. Mk Tag: Access to the I2C_CALLBACKS data in a video miniport Tag: 81762

    - Setting DefaultInputSlot in a PPD? Hello all, I build print drivers with the PostScript OEM customization tools, and I'm stuck on some driver/PPD interaction. The second tab in DocumentProperties is normally Paper/Quality, with two drop downs for Paper Source and Media. These are populated from the PPD via InputSlot and MediaType sections. The problem is that the PPD parser (or some other component) does not honor the DefaultInputSlot and DefaultMediaType directives, and it does its own thing. I'm using the German version, and the phrase "Automatisch Auswahlen" ("Automatically Select") is filled in for us. This phrase does not appear in the PPD, but does appear in PS5UI.DLL's resource section. This all means that we're not able to set a reasonable default, and this is causing us some real problems for a customer implementation. If we change the default in the UI, it "sticks", but we don't have portable access to the DEVMODE to muck with it ourselves. Looking in the MSDN docs: http://msdn.microsoft.com/library/en-us/print_d/hh/Print_d/pscript_34563439-cd1f-4418-b51d-a3250e35df28.xml.asp It seems clear that InputSlot is being handled specially, and it suggests to me that DefaultInputSlot is simply ignored entirely. Looking at the IPrintOemDriverPS::DrvGetDriverSetting helper function, it seems that I'm able to *fetch* values, and IPrintCorePS2 lets me enumerate them, but I think I cannot find any mechanism to *set* these options. Is there any way I can set a default value for this field when the driver is installed without requiring the user to click a box after install?

    - I2C slave device address Hi all, I am in a very strange situation for the I2C bus slave device address manipulation. Basically I have some slave devices which I communicate over the I2C bus. They work fine on different machines with Intel motherboard. The problem arises when I connect a specific slave device to the Intel 82865G machine. The address I am sending over the I2C bus for the slave device is not acknowledged by the device. The same address is acknowledged by the device on another intel machine. According to the I2C specs, the slave device is supposed to send the acknowledgement when Master finsishes sending the Bits of the address byte by pulling the SDA line low. But in this case the slave device is not pulling the SDA data line low. I have tried many cases.. like increasing the delay between the SCL , SDA check, checking the video memory, assigning the different address. But nothing is working. I am not sure whats the difference between I2C bus on one motherboard and that of another. Both are Intel 82865G. I communicate with the I2C in a driver for a graphics cards and for Intel I directly get the Video memory, convert it to the Physical memory and write to the DDC registers. I am able to send the Start condition on the I2C bus , but when I send the address of the Slave device , its not acknowledging. Other slave devices of Same type work fine. It will be very helpfull If somebody can tell me whats going on over the I2C bus for this. Thanks. -- Abhijit. Tag: Access to the I2C_CALLBACKS data in a video miniport Tag: 81752

    - How long does it take to read a usb report? I am trying to check what is the maximum speed for read/writes of my pic 18f4550 usb device. It is a full speed device and an 8 byte length report, and I am using ReadFile and WriteFile. My results are that I get about 100 read write cycles in one second. Is that a normal speed for 8 byte reports? It seems quite slow ? My C loop is tight, and my device is a loopback device, i.e. it simply copies the input to the output?

    - Ndisprot problem with Intel Pro/Wireless 3945ABG Hi, I have developped an application able to control the laptop wifi adapter by setting and querying the oids OID_802_11 via the Ndisprot provided in Windows DDK 3790. This application works perfectly with the chipset Intel Pro/Wireless 2200BG and Intel Pro/Wireless 2100 and many other chipsets. The problem is that when I try to use it with the chipset Intel Pro/Wireless 3945ABG the oid OID_802_11_SSID does not work. The connection is simply not established and the IP is not retrieved. All the others oids works fine. Did you have any idea about it? Is it a known bug? Did you ever try the Ndisprot with Intel Pro/Wireless 3945ABG? I've already tried also the Ndisuio approach (using the source code of the DDK 2600.1106) obtaining exactly the same result: no connection is established when the OID_802_11_SSID is set. All the others oids works fine. Thanks Davide Tag: Access to the I2C_CALLBACKS data in a video miniport Tag: 81723

    - 1394 peripheral device identifcation (1) My driver is similar to 1394diag.sys which installs above Microsoft 1394 stack in Windows 2000/XP. This is unsigned driver. DeviceID for 1394 peripheral device is 1394\VendorName&ModelName. All my peripheral devices use same VendorName and ModelName. Still when a new peripheral device is connected, Windows 2000 and XP comes up with "New Hardware found" wizard. How can I avoid this? I donâ??t mind if I get warning "unsigned driver", but I canâ??t install driver again and again. Is driver signing required here to stop Windows prompting for driver for different EUID? DeviceId is same for all my 1394 devices and EUID is unique. What is the meaning of DeviceId if EUID is considered for DeviceId. (2) Is there any auto install method for driver to 1394 peripheral devices? I am looking for a way to have unique driver installed once for VendorName and ModelName. I know there are some topics in newsgroup. But what I dont understand is document clearly states driver for device is identified by VendorName and modelName. Documentation doesnot say driver has to be installed for every device if driver is unsigned. It only says driver installation will give "Unsigned driver" warning. So I am not sure if this is happening because driver is not signed or is it because of some other error/option in my own installation. (3) I didnâ??t see any driver signing document for peripheral drivers to 1394, found only 1394 bus drivers documentation.

Is windows logo requirement and driver signing are same? I am not able to find how to get my driver signed. This is 1394 driver for peripheral device. This driver is on top of Microsoft 1394 stack and is designed in the lines of 1394diag.sys. All I can find is 1394 bus driver or 1394 hardware. I cant see any mention of 1394 peripheral driver. I dont understand why 1394 peripheral link is not even refered from 1394 bus driver. Someone please refer the link.

    - Conflicting errors code with USB Bulk requests When our USB function driver is used in a loop or for a long transfer of data (MBs)on a Bulk endpoint, after a short period of time the I/O status (IRP) returns a failure but the URB status is successful. This is after hundreds of successful requests. The IRP errors have been STATUS_IO_DEVICE_ERROR or STATUS_IO_TIMEOUT. The URB status is USBD_STATUS_SUCCESS in either case. In what conditions would the Windows USB stack return these errors and the URB be successful? Second question, when testing for IRP error codes from a IOCTL_INTERNAL_USB_SUBMIT_URB request, which I/O status should be tested? IO_STATUS_BLOCK ioStatus = { 0, 0 }; PIRP irp = IoBuildDeviceIoControlRequest(...., &ioStatus); // Boilerplate code... ntStatus = IoCallDriver(pdx->lowerDeviceObject, irp); if (ntStatus == STATUS_PENDING) // Wait on event At this point is io.Status.Status == irp->IoStatus.Status ????

    - Does the stream device have the recived/send buffer?If yes,where does it define? Hi All, When I write the MC8051 program,there is buffer to recive or send the date in the UART communication.And if there is date recived we can read the buffer directly instead of reading the bit one by one according to the timing graph. However,Does the WinCE driver program have the same mechanism as MC8051? If yes ,generally where is the buffer defined?Is it a register? For example,the driver of the AC97 ,...\WINCE420\PUBLIC\COMMON\OAK\DRIVERS\WAVEDEV\UNIFIED\ENSONIQ\ How does the chip read the media file and render?Is it one bit by one bit,or read the buffer?

    - TDI Client vs Winsock A few questions on TDI clients that someone may be able to answer: 1. In general, should there be appreciable differences in TDI client vs. Winsock throughput and latency over LAN or wireless links? 2. Does Winsock implement SO_SNDBUF/SO_RECVBUF sizes in afd.sys or in other components? That is does a TDI Client have to reimplement buffering or is it just an option passed to tcpip.sys (like TCP_NODELAY). 3. Can TDI clients issue more than 1 send irp at once? How would that affect throughput/fairness? Thanks. Tag: Access to the I2C_CALLBACKS data in a video miniport Tag: 81013

I know the Underground1 use the DirectInput8 to retrieve the data of mouse and keyboard(GetDeviceData() for the keyboard,and GetDeviceState() for the mouse) , the Underground2 use the the DirectInput8 to retrieve the data of keyboard and the click of mouse (GetDeviceData() for the keyboard,and GetDeviceState() for the mouse) .But what is the way the Underground2 used to retrieve the mouse's position?
