    - Problems sending named events to Driver Hi NG My driver has problems recieving a event from my user mode applikation. But there is no problems recieving the same event in my appilication from the device driver. Thia is what I do: In my DriverEntry i create the event with this: // Create event for user-mode processes to monitor RtlInitUnicodeString(&uszNotifyEventString, L"\\BaseNamedObjects\\AppEvent"); // Trying to create the event NotifyEvent = IoCreateNotificationEvent(&uszNotifyEventString, &NotifyHandle); if(NotifyEvent) { // Success KdPrint(("NotifyEvent event created with success\r\n")); // Clear it... KeClearEvent(NotifyEvent); } I get the handle to the event in my application like this: // Creating event. ITs created by the driver.. hEvent = OpenEvent(SYNCHRONIZE, FALSE, _T("AppEvent")); if(NULL == hEvent ) { return 0; } They both succed. My application then waits for the event: // The events used.. hEvents[0] = pService->HEndThread; byNumOfEvents++; hEvents[1] = hEvent ; byNumOfEvents++; dwWait = WaitForMultipleObjects(byNumOfEvents, hEvents, FALSE, INFINITE); if((WAIT_OBJECT_0 + 1) == dwWait) { // Set event again. Driver does not respond to this SetEvent(hEvent ); <----- No responds in my driver on this } When my driver signals the event ( KeSetEvent(NotifyEvent, 0, TRUE) ) my application is responding OK to the event But when my application sets the event my driver does not respond to it. // Setting event KeSetEvent(NotifyEvent, 0, TRUE); <--- My application responds to this KeResetEvent(NotifyEvent); // Waiting for the service to answer status = KeWaitForSingleObject(NotifyEvent, UserRequest, KernelMode, FALSE, &WaitTimeOut); // Never reached. if(STATUS_SUCCESS == status) { KdPrint(("Got event.\r\n")); // Service has answered. Clear the event. Shutdown in progress KeResetEvent(NotifyEvent); } Any Idea ?? Schould I call the OpenEvent() with EVENT_ALL_ACCESS instead of SYNCHRONIZE ?? If I do I got an error that say "Access is denied". How can I create the event with privilege to do this ?? Thomas Tag: [Q] USB Mass Storage Device IOCTL failure Tag: 27659

    - Error STATUS_NO_LOGON_SERVERS on HalAssignSlotResources We've developed device driver for PCI device, which worked fine on Windows 2000 and Windows XP. BUT after we installed the latest SP4 for the Windows 2000, the call to the HalAssignSlotResources returns error 0xC000005E , which is translated as STATUS_NO_LOGON_SERVERS. What may be the reason of such behavior? Tag: [Q] USB Mass Storage Device IOCTL failure Tag: 27644

    - How to get the current link speed of wireless i dont know how to get the current link speed in my application using NDIS protocol DRIVER, but i know i should use the function "oid_802_11_gen_link_speed". However, i dont know how to use this function. who can tell me this? i never find any sample i need. So, if possible, who can post his/her parts of coding about it? it's emergency! :< Tag: [Q] USB Mass Storage Device IOCTL failure Tag: 27630

    - meaning of INetCfgComponent::GetDeviceStatus() What exactly is the "status of a network card" (DDK docs) returned by INetCfgComponent::GetDeviceStatus() in 'pStatus'? The docs do not say anything about how to interprete the value returned. Stephan Tag: [Q] USB Mass Storage Device IOCTL failure Tag: 27626

    - WAVERR_BADFORMAT Error I've got an app plays wav files in MULA format (7) using the standard API calls (waveOutOpen, waveOutPrepareHeader, waveOutWrite, etc.). This app has been running without problem on hundreds of machines and every operating system Microsoft has put out from Windows 95 to Windows XP. Suddenly we've got a client using NT 4 SP6 who's getting WAVERR_BADFORMAT errors returned from waveOutOpen. When I call waveOutGetDevCaps on the device, it puts 4095 in the WAVEOUTCAPS.dwFormat field. Anybody have any ideas what might cause this? Tag: [Q] USB Mass Storage Device IOCTL failure Tag: 27524

I'm developing a USB mass storage device with an additional
functionality.

There is no problem in locating the device's symbolic link, using
SetupDiXXX functions. But if I try to DeviceIoControl()
IOCTL_STORAGE_GET_DEVICE_NUMBER, IOCTL_SCSI_GET_INQUIRY_DATA, and
other disk and storage control codes as well, after opening the device
through CreateFile() with the following symbolic link name, it fails
with the error code 50, which means ERROR_NOT_SUPPORTED.

\??\USB#Vid_0c76&Pid_0005#0304281630200#{a5dcbf10-6530-11d2-901f-00c04fb951ed}

To be more precise, my USB storage device supports Bulk-Only Transport
protocol and announces itself as a SCSI transparent subclass device.

If there is anybody who had ever stuck in this type of problem, please
give me some clues for solving it.

I have one more question. I'm in the position to develop hardware and
software. So for now, I'm trying to compose a small program
controlling a mass storage device of another manufacturer. If I'm to
develop the firmware without relying on the USB controller customized
to the specific application, do I have to write a firmware parsing all
the SCSI command set? Or is there any documentation that specifies
which part of the standard SCSI command set USB mass storage device
spec supports? I'm afraid if I have to deal with a whole bunch of SCSI
command set. Need some advice.

Thanks
