    - USB Driver : 0xC0000B00 + 0xC000A00 errors with Isochronous OUT Endpoint when ASAP is specified ! Hi, My device supports an Isochronous OUT Endpoint, set to 895 bytes/ms. Also I would like to fully use this endpoint (ie : fill in all Isochronous OUT frames each millisecond). To do this, I implemented a stuff that sends 4 pending URBs to the USB Bus driver. Each URB also gets completed but some are completed with 0xC0000B00 error (USBD_STATUS_ISOCH_REQUEST_FAILED). For those URBs that fails with this error, Iso packets (that do not have data) are told to be in error (0xC0000A00 = USBD_STATUS_BAD_START_FRAME), whereas all URB are sent with the USBD_START_ISO_TRANSFER_ASAP flag. Does anyone knows this kind of problem, and is there any trick to fix this problem ? Thanks by advance !

    - Using DIFxApp for Net Client install I've been trying to use the DIFxAPP code to install our NFS Client Device driver and have been running into problems. The DIFxAPP code requires a WHQL digital signature.for use with Windows 2000 and XP. Since we have no hardware we cannot take advantage of that program. An Authenticode signature can be used for Windows Server 2003, but apparently not for Win2k and XP (According to the Authenticode doc anyway). Has anyone else run into this problem? Any workarounds? Does anyone know why a WHQL digital signature is a requirement? Any idea if this requirement might be relaxed in the future? The error that cat get past is 0x800B0100L which is "No signature was present in the subject." I have supplied an Authenticode signiture, so I'm guessing that it wants a WHQL digital signature, correct? Regards, Duane Johnson WRQ, Inc.

    - Terminal Server, virtual audio driver, and lossless audio I was unable to locate a better newsgroup, so if there is a better place to post this question, please let me know. I am working with streaming audio over a Terminal Services connection in Windows 2003 Server. However, the application we'd like to use will be used in an audiological setting, so having lossless audio is of paramount importance and there doesn't appear to be a way to configure the virtual audio driver to use a lossless codec for transmission across the network. My question, then is this: Is there a way to configure the virtual audio driver for Terminal Services to use lossless compression? If not, to whom would I speak in order to have this option implemented in a future version? Thank you for your time in this matter.

    - 2 device interface questions Hi, i use SetupDiGetClassDevs to build a list of devices, and then i use SetupDiEnumDeviceInterfaces to enumerate device interfaces. however, if i do not specify DIGCF_DEVICEINTERFACE and use the same classguid that i use for SetupDiEnumDeviceInterfaces, the enumeration fails. aparrently if i do not specify DIGCF_DEVICEINTERFACE, i get a list of setup classes. what is the use of this if i cannot enumerate device interfaces with the resulting list? my second question is simpler: i am making an api to handle the device driver interfacing. a user needs to have something that he can pass to the api that i am making, in order to say: open a connection to that specific device. does he need to use the detailed name that is returned by SetupDiGetDeviceInterfaceDetail? or is there a simpler way to do this? kind regards, Bruno.

    - Custom IOCTL for Audio Drivers Hello I have been trying to adapt MSVAD DDK sample so that it can handle custom IOCTLs from user mode apps. I registerd an handler for IRP_MJ_DEVICECONTROL and use PcDispatchIrp() to send down unrecognized IRPs to PortCls. since the MSVAD sample demonstrates an audio driver thats PnP aware, its not advisible to create a symbolic link for the driver such that usermode apps can open "\\.\mydriver" and send IOCTLs. I was wondering, how should one go about exposing the driver in such a way that user mode apps can send custom IOCTLs to it.

    - how to display messages during boot time Hi, I have written a scsi miniport driver and it works well when I choose the "multi(0)disk(0)rdisk(0)partion(1)..." option defined in the boot.ini during boot time. I copied the driver into the root and renamed it as ntbootdd.sys. I added another option "scsi(0)disk(0)rdisk(0)..." in the boot.ini. When the system boots, I choose the scsi option. But the same driver ntbootdd.sys seems failed. I want to display some messages to the text mode screen in my driver like ntldr.exe does, so I could debug my driver. Does anybody know how to do that ?

    - bug (?) in SfGetFileName in the SFilter sample, SfGetFileName will produce a string from various pieces. It gets a device name, a related file name (if any) , and then the filename and glues them together. I'm seeing that when a file from the network is being written, the device is \device\harddiskvolume2 then the related file object is '\' and then the routine appends a \ also finally the file name is \test\alpha.txt. This results in a name = \device\harddiskvolume2\\\test\alpha.txt.

    - IOCTL and mutex Hello I guess I am little confused and would appreciate if someone were to help me resolving this. I have written a driver for PCI based device to be meant to be used on Windows 2000 and up. The device has a few controls that the user application can get and set through IOCTL interface that I have provided in the driver. In order to serialize access to ioctls, I use Kernel Mutex as shown KeWaitForMutexObject(&pdx->ioctlMutex, Executive, KernelMode, FALSE, NULL) ; /* do stuff */ KeReleaseMutex(&pdx->ioctlMutex, FALSE) ; I could have used spinlocks but I reasoned that Mutex would work just as fine in this case because driver would not be in an arbitrary thread context while processing IOCTLs and I could spare raising the IRQL to DISPATCH. Also, I should mention that my driver installation does not put another filter driver on top of my driver. Now I am wondering if my above reasoning is indeed correct. In other words, can it ever happen that, either on XP or windows 2000, the driver receives IOCTL in an arbitrary thread context in which case I should probably switch to using spinlocks.

    - Restarting a print job I work for a small printer manufacturer as a software engineer developing. I'm currently modifying a USB print driver to add an error recovery capability, it should allow a job to be reprinted from the same page where an error happened. I've already implemented this feature for a parallel port driver but I'm facing some problems now that I'm trying to do the same for USB port. The problem is as follows: 1. When an error condition is detected the Language Monitor's WritePort function stops sending data to the printer but keeps reading data from the print spooler unitl it detects an end-of-page token. 2. When this happens I set the job to be restarted using the SetJob function using the command JOB_CONTROL_RESTART. 3. I can see in the print queue the job restarting and respooling. The print spooler starts sending data again to the Language Monitor. 4. This is when the error happens. The WritePort returns error 183, which is "Cannot create a file when that file already exists". So, I read some documentation and tried some option without much success. My best gess is that the print processor is not being restarted. There is two files (FP00000.SPL and FP00000.SHD) that are never deleted as the way the should when this error happens. I tried to use the ControlPrintProcessor() function to terminate the print processor manually when the job is done, but I couldn't get the correct handle. Did some one have this problem before? any suggestions? Sincerely, Fabio Milan Tag: USB Driver : 0xC0000B00 + 0xC000A00 errors with Isochronous OUT Endpoint when ASAP is specified ! Tag: 50159

    - FILE_DEVICE_DISK and VPB in a device filter Good people: I've a question about the toaster filter sample attaching to the disk stack. The filter calls IoCreateDevice specifying FILE_DISK_UNKNOWN on wxp since IoIsWdmVersionAvailable(1, 0x20) returns TRUE. Later in AddDeviceRoutine, the newly created device type was update with the lower's type which is FILE_DEVICE_DISK. I/O manager didn't create a VPB for the DO since it was FILE_DISK_UNKNOWN at the time it was created. Is there anything bad if the topmost device object is DEVICE_DISK but the VPB is NULL? It didn't crash on XP though.

    - how to stop network search for Microsoft Kernel Components? Hi, I'm deeply appreciated if anyone can provide clues on the following: I try to install an audio device through INF file in a system with fresh Windows XP. After the driver loaded, i could see a list of unknown devices in the device manager and it turns out that it is the OS tries to load up the Microsoft Kernel Components. However, it takes extremely long time just to load up each components. I notice that if the network cable is disconected, the loading time of those components takes only few seconds. It seems to me that the OS tries to scan through the network for the latest kernel components (correct me if I guess wrongly). 1. What is the bypass this network search process? 2. Can a device coinstaller affect it in any way? Thank you so much :) Tag: USB Driver : 0xC0000B00 + 0xC000A00 errors with Isochronous OUT Endpoint when ASAP is specified ! Tag: 50129

    - more on timing problems Hi everybody, I've managed to solve the problems due to the dpc's wait on queue of some post ago. Now I'm facing another strange (for me) behaviour: the device is interrupting every 1ms to signal data transfer completion, it uses a couple of buffers that fills in a ping-pong way. During my tests I moved the whole data copying process from the dpc to the ISR, and I noticed that from time to time I seem to miss an IRQ, or my isr is interrupted and the remaining processing takes place too late to be useful. Raising the IRQL to HIGH_LEVEL doesn't change the behaviour, and I have observed that simply launching some application multiplies occurency the 'loss' effect. One of the tests consists in attaching a machine to the device, the machine 'pumps' a stream of bits, and checks to see if the bits returning down the cable are the same, signalling an error if not. Copying the data from the read to the write buffer directly in the isr should solve every delay problem, but still the tester equipment detects some error, and as I said, launching some application multiplies the errors during the startup phase. It seems not to be a CPU load problem, I suspect that some higher priority interrupt is processed before/during mine; how can I determine who's interrupting with an higher priority? Has someone any ideas on how circumvent if not solve this behaviour ? Thank you. e Tag: USB Driver : 0xC0000B00 + 0xC000A00 errors with Isochronous OUT Endpoint when ASAP is specified ! Tag: 50086

    - scsi miniports DriverEntry is called but on other function... Hi folks, i am writing a scsi miniport driver for a pcmcia flashcard. The drivers DriverEntry() function is called as soon as a pccard is plugged in. (Thats why i assume the driver is installed correct.) DriverEntry() return the value zero which is returned by ScsiPortInitialize(). After DriverEntry() has been called, no other function is called but the device appears with the message " This device cannot start. (Code 10) " in the device manager. So the question is: Why does'nt the system call HwFindAdapter() after the driver service has been started? Please let me know if you have any ideas.

    - About USB device and interface descriptors Hi, To my understading device and interface descriptors contain a usb device class type that recognizes the functions the device implements (audio, storage, printer, etc.). There are a few things I do not understand about the usb device class concept: 1) What is the purpose of the device class mentioned in the device descriptor ? The class is mentioned in the interface descriptor and a device may have many interfaces. Are there cases where the class in the device descriptor is not 0xFF or 0x00 or the same as in the interface ? 2) Say a usb mass storage device reports an interface class of 0x03 (HID), but it still reports "USB Mass Storage Device" in it's device description. Am I right in guessing that the USBSTOR.SYS will still be loaded and a file system will still be mounted regulary ? If so, what is the credebility of this parameter if windows doesn't really care what is it's value ? 3) Isn't there a networking usb device class ? The Wi-Fi USB device I just bought reports a interface class of 0xFE and subclass 0x01 which according to the documentation is an infra-red device and the infra-red device I bought reports 0xFF in the device class and 0x00 in the interface class (and 0x00 is illegal to my understanding) ? 4) From my observation the compatible ID's a PDO for a USB device sometime contain the class and sub class from the device descriptor and sometimes from the interface descriptor. What is the algorithm for this decision ? 5) To my understanding when a device implements more than one interface the PDO reports a USB\COMPOSITE compatible ID, yet the PDO for the bluetooth adapter I bought does not report this ID. how can this be ? I hope this is not too many questions in one shot... Thank you Shahar Tag: USB Driver : 0xC0000B00 + 0xC000A00 errors with Isochronous OUT Endpoint when ASAP is specified ! Tag: 50037

    - Removal MO and WM_DEVICECHANGE messages. Hello, I am running Windows XP and I have a Fujitsu 2513A MO drive attached to a Adaptec 29160N controller. I am attempting to write an application that traps WM_DEVICECHANGE messages looking for DBT_DEVICEARRIVAL and DBT_DEVICEREMOVECOMPLETE messages. So far it seems to work famously for CD and DVD media, but the drivers for the MO drive do not produce the expected messages. The strange thing, however, is that AutoPlay does work for the MO drive - and so I had a question for any of you: is there some way I can leach onto the same mechanism that AutoPlay is using to detect media insertion/removal into/out of that drive? If so, what is that mechanism? And why is it apparently different from the WM_DEVICECHANGE mechanism? BTW I have tried looking for updated Windows XP device drivers for the drive, but to date I could not locate any.

    - How to flush/purge pending USB comms messages? Hi all, Was wondering if anyone knows of a mechanism whereby I can purge any pending USB comms? I'm thinking along the lines of a PurgeComm for serial devices. I have a situation whereby my firmware running on a remote device is getting out of sync with the application running on a PC, and I'd like to 'reset' the comms link without having to do a close and (re) open of the device?

    - Problems getting the 1394 ROM configuration info I am new to device drivers and am working on a driver for a 1394 firewire video device. I am having some problems in getting the ROM configuration info. I am able to perform multiple async reads of 4 bytes at a time to read the ROM data starting at 0xFFFFFF0000400 and continuing until I have read the entire contents of the config info. And I have verified that all of the retrieved data is correct. But if I try to read anything more than 4 bytes at a time, I just get all zero's back. First question....Is there a limit to the number of bytes that can be retrieved at a time when reading the ROM config info? Next, I tried calling REQUEST_GET_CONFIGURATION_INFO in the IOCTL_1394_CLASS to get the buffer sizes of the Unit Directory, Unit Dependent Directory, Vendor Leaf and Model Leaf by first setting each of these values to zero before making the call. After returning success, the call only seems to set the u.GetConfigurationInformation.UnitDirectoryBufferSize value to 12 (which is incorrect) and leaves all others at zero. Why does it not return the correct values? At worst case I can just take the retrieved data from my first technique and extract the same information as the call to REQUEST_GET_CONFIGURATION_INFO should have done but I want to find out why this call doesn't seem to work for me.

Hi,
My device supports an Isochronous OUT Endpoint, set to 895 bytes/ms.
Also I would like to fully use this endpoint (ie : fill in all
Isochronous OUT frames each millisecond).
To do this, I implemented a stuff that sends 4 pending URBs to the USB
Bus driver. Each URB also gets completed but some are completed with
0xC0000B00 error (USBD_STATUS_ISOCH_REQUEST_FAILED).
For those URBs that fails with this error, Iso packets (that do not have
data) are told to be in error (0xC0000A00 = USBD_STATUS_BAD_START_FRAME),
whereas all URB are sent with the USBD_START_ISO_TRANSFER_ASAP flag.
Does anyone knows this kind of problem, and is there any trick to fix
this problem ?

Thanks by advance !

Sebastien
