    - determining what property sets are supported by a WDM streaming device Is there a way for an application to enumerate all the property set GUID's that a given WDM streaming device supports via its IKsPropertySet implementation? (I would like an application I am writing to have its own UI for all the properties supported by a given streaming WDM video capture device, even its custom properties.)

    - Help required with ddk sample FPFilter I compiled the 'fpfilter' driver from the ddk samples and the 'addfilter' app which is used to apply it to disk volumes. In the fpfilter I find an 'inf' file, I installed it with the 'install' context menu of explorer, then I added a volume with addfilter, then rebooted, and it doesn't work, i.e. the drive letter which corresponds to the volume has now disappeared from the explorer folder view?

    - How to obtain a Handle on Tescap driver ?? Hi, I actually try to modify the TestCap sample of the DDK. And I would communicate with it in a user-mode application but I can't obtain a handle on it. The CreateFile functions always reject the name of the driver. Could you help me ?? I've found a message named "Use IOCTL in testcap ddk sample question?" but it was not useful for me... Tag: Multiple Report ID Problem Tag: 88223

    - dont get the removecomplete message from the window XP. Hello, I'm working on WIN32 application which monitors and passes data from and to USB Device which also support serial communication . I monitors device arrival/removal notification ( Serial Port ), by the way, especially while I try to read data from USB device, if i remove usb device from PC, I dont get the removecomplete message from Windows. My process is the following. 1) Device Arrival ( Serial Port -DBT_DEVTYP_PORT) 2) Open Serial Port 3) Write/Read Serial Port 4) Close Serial Port 5) Open USB Device Port 6) Write/Read USB Device 7) if Read Failed, Close USB Device Handle 8) Device RemoveComplete ( Serial Port - DBT_DEVTYP_PORT ) ==> dont get that message . The Device Driver Developer said to me that He verified the following fact. My app closes serial com port, and closes USB Device port, and Device Driver called WinAPI for Windows Event iosetdeviceinterfacestate() to OS. => But My App or the other windows event collector(test program ) dont get that messages. After I kill My App, The RemoveComplete Event is notified. Except closing opened port, what else should I do? Any suggestion will be appreciated.

I wrote a usb camera filter driver that can do some processing before the image data was submited to the appliction from the driver. Now I can modified the image data(which comes with the IOCTL of IOCTL_KS_READ_STREAM), but I can't get the format(such as size, rgb or yuv...)of current stream.

    - Vista, rollback driver In the escrow build, x86, I've updated an inbox driver to my test signed version from Device Manager. It complained that the driver is unsigned, created restore point, etc. Later I wanted to roll it back, but the rollback button was grayed. I did uninstall and remove files. Then Vista immediately found and reinstalled the in-box driver. Two questions: a. Why the roll-back button was grayed? Some error on my side, or a feature of Vista? b. Can we disable the immediate reinstall after removing a driver, or is this considered for future? (Why: suppose that the previous version is bad and crashed. Restoring it will result in... yes, crash ). Regards, --PA Tag: Multiple Report ID Problem Tag: 88192

    - Mouse Development, use HID-USB or RS-232? Hello, As my senior design project i'm developing a computer pointing device that i'd like the computer to interpret as a mouse. The mouse will eventually be designed to support movement in three dimensions, however if i can just get limited functionality working with the PC, i'll be happy. In that case, i'm trying to determine the best way to implement PC connectivity with the device. I'm trying to wage the amount of effort needed to connect the mouse using the USB HID protocol. The problem is i'm having trouble finding resources on implementing a USB HID device. The datasheets for the microprocessors i'm considering do not document HID integration very well with their devices. Does anyone have any suggestions as to implementation methods (USB or RS-232) ? would HID be the best option even if supporting three dimentions? thanks in advance Tag: Multiple Report ID Problem Tag: 88167

    - Bugcheck D1 in ks.sys I've written an AVStream video capture driver. When I turn on DriverVerifier, I get bugcheck D1 (!analyze -v output is below). It happens when I insert the filter into GraphEdt.exe, render the preview pin, and hit play. The bugcheck occurs after the first call to Process (right after entering the Run state). The memory being accessed (e3987bc8) is indeed pageable; !pool e3987bc8 2 shows: Pool page e3987bc8 region is Paged pool *e3987b68 size: 70 previous size: 28 (Allocated) *KSpf Owning component : Unknown (update pooltag.txt) It appears the KS.SYS has allocated the KSGATE structure from paged pool (the tag "KSpf" is not used in my driver, so I'm guessing it is KS). It also appears that KS.SYS is calling KsGateTurnInputOn at DISPATCH_LEVEL. I have added code to all of my functions to capture the IRQL coming in, and check it going out, to make sure it is the same; it comes up clean, so I'm 99% sure it's not me forgetting to release a spinlock or something. Any ideas? Oh, this is running on XP Pro SP2, with all the latest updates installed. TIA, -- mkj _______________________________________________ // // Michael K.

    - ScsiPort and mapBuffers Folks, I have a scsiport miniport driver. The hardware I talk to supports DMA so I do not need system virtual address for doing read/write commands. However I need to emulate some SCSI commands and need mapped buffers for non-read/write commands processing like test unit ready etc. In scsiport model if I set the mapBuffers to TRUE I will get system virtual address in data pointe for all commands including read/write commands. I beleive creating this mapping is a costly operation. I there a way I can set the mapBuffers to FALSE and then for non read/write commands only get a virtual address to map the physical address? Since my driver is an experimental driver I am fine using "disallowed" windows driver commands. Any help much appreciated. Thanks in advance. regards vs Tag: Multiple Report ID Problem Tag: 88148

    - How to implement blocking ReadFile() call in the driver Hi all, I am implementing a driver for windows XP which interacts with a device and exposes that device to application via file interface (CreateFile(), ReadFile(), WriteFile() APIs). So now if a user application needs to communicate with the device then it opens file handle to the device \\Mydevice and then uses ReadFile() to read packets from the device and WriteFile() to write packets from the device. Problem is that this reading and writing can be done simulataneously using multiple threads (one thread for reading and one for writing). Currently in the reading thread I call ReadFile() to read packets from the device in a loop and if there are no packets to read I go to sleep for some time and then try reading the packets again. Code is like: While(TRUE) { if(ReadFile(m_hFile, buffer, MAX_BUFFER_SIZE, &bytesRead, NULL) == 0) { // An error } else { if(bytesRead > 0) { // Do something with the data } } Sleep(SOME_TIME); } I want to change my implementation of ReadFile() in the driver to a blocking ReadFile() so that my ReadFile() only returns when either there is a data packet or an error has occured (like for example I close the file handle from some other thread). May be its just a beginning level question, but if you could guide (some links or hints etc) me how can I do this, I will really appreciate. Thanks, Arsalan Tag: Multiple Report ID Problem Tag: 88129

    - Preventing current NIC instances from stopping when installing new For Windows 2003 Server, I have a device driver that is basically an NDIS ethernet miniport on the upper edge and a WDM driver on the lower edge. This device lives on a virtual bus that I have control over. I have a problem when I try to install new instances when there are current running instances. The network class installer seems to always restart all instances that use my driver. I would like to dynamically add instances of my device on my virtual bus, and have the device installer connect up my NIC driver to the protocol bindings withough disrupting traffic on current instances. I have other types of devices on my virtual bus (storage and WDM) and do NOT see this behaivor, so am fairly convinced the network class driver somehow is marking all device for my driver as needing to restart. Looking at verbose logging in setupapi.log clearly shows all instances getting removed and then started. This looks like it happens after the network class installer has returned from DIF_INSTALLDEVICE. Turning on logging of netcfgx on the checked build didn't produce any good clues either. I've done some experiment with the Intel NIC driver and find it has exactly the same issue I have. I also find the network class installer even needs to restart virtual nics used for vlan tagging in the Intel NIC driver. I'm currently using a command line program from Microsoft available in source form that installs a specific inf to a specific Pnp instance id. It's in KB 889763. I basically need to find a way to modify the program in KB 889763 to set the correct options such that current NIC instances don't loose connectivity when I install a new instance. It could also be I need to write a class or device coinstaller to modify something in the install process, like perhaps post processing of the DIF_INSTALLDRIVER message, to turn off whatever flags are causing the restart. If somebody from Microsoft could tell me what causes the network class installer to restart all NIC instances, I could perhaps find a way to solve this.

    - communicating with TCP on smartcard I want to put the TCP stack in a smartcard and use it to communicate with any program using TCP. The standard PC interface to a smartcard is via PC/SC that implements a normalized half-duplex protocol (usually T=0). In a sense, the smartcard is like a (very small) computer and communication to it is via PC/SC. In general if an application wants to connect with TCP to a remote TCP, any data packet from the application is routed by IP to the correct host - in this case the smartcard. One way to implement this is to have a server program on the PC that gets the IP datagram and forwards it (in pieces of at most 255 bytes) using PC/SC to the smartcard (possibly with some point-to-point protocol), i.e. it acts as a 'network device or adapter', somewhat similar to an LAN-WAN (e.g. X.25 or ATM) bridge. I have some questions about this: - Is this the only way to go about it? - What API (if any) do I use to get an IP datagram destined for a specific IP address? - If such API does not exist, must I write a 'device' driver adhering to NDIS and all that?

    - IOCTL_HID_SET_FEATURE Hello, i've to power off a UPS via feature report. In usermode, this works fine with HidD_SetFeature(). I also have to do this is in a driver. I tried this by the use of IOCTL_HID_SET_FEATURE. When using this ioctl out of my driver, hidclass BSODs ( access violation ). So I think, the buffer sent via IOCTL_HID_SET_FEATURE is wrong - how must it look like? I tried to fill the buffer with 'power off command' only and to set it to a pointer on HID_XFER_PACKET. How to use IOCTL_HID_SET_FEATURE correct?

    - kernel mode audio - need some clarity Hi, Im workin(just sarted out, so pretty much a newbie) on an upper filter driver, and I need to clarify a few doubts: 1) Can an upper filter driver implement kernel streaming?(if there is no straightforward way, is there an indirect way?Hints please :)) 2) This miniport thing is a bit confusing. Can there be more than one mini driver in a devices "driver stack"? More specifically, can my upper filter driver implement a wave cyclic miniport when it is implemented by the functional driver too? 3) Is there more than one standard way in which actual audio data may flow down the wdm layers of an audio device? What are these way(s)? 4) What are "pins"? What is required to implement them? 5) Can audio data flow through an upper filter driver of an audio-out device at all? yes, i know (a)this topic has been discussed in some forums. However, thanks to contradicting posts and some irritatingly "so close but yet so far(conceptually)" threads, I am well and truly confused. (b)that I should read Walter Oney's book. unfortunately its not available in the city I live in. (c)that I should read Microsofts DDK documentation. I have been trying to do this for some time now. I am more confused now than when I started out( I gues partially because there is nothing audio-filter-driver specific). Dont send me back there. Have mercy!

    - NDIS MiniportSendPackets called after MiniportShutdown We have encountered crashes on shutdown with our NDIS 5.1 WDM miniport driver. The crashes may occur on less than 1 in 500 reboots on MP systems with the latest multi-core CPUs. The problem seems to be a synchronization problem. A common server has 2 NICs, but servers can have up to 32 NICs installed. On shutdown the driver's MiniportShutdown routine is called for each NIC instance. The DDK states: >MiniportShutdown does nothing more than restore the NIC to its initial state >(before the miniport's DriverEntry function runs). However, this ensures that the >NIC is in a known state and ready to be reinitialized when the machine is >rebooted after a system shutdown occurs for any reason, including a crash >dump. >MiniportShutdown should not release any allocated resources. >MiniportShutdown should just stop the NIC. That is what we do. At the start of MiniportShutdown we set a flag in a global driver structure that the NIC is shutting down. The NIC is stopped. The receive DPC for the adapter will not pass up any more packets and any queued send packets are returned by calling NdisMSendComplete. The driver may queue send packets if it could not send the packets in the context of its MiniportSendPackets routine. That could happen under heavy network load for multiple NICs. But, in the case of the shutdown crashes the systems were basically idle. What we see is that the MiniportSendPackets routine is called by NDIS after the MiniportShutdown routine has completed for the same adapter. The crash occurs in the MiniportSendPackets routine, because the MiniportAdapterContext handle that is passed to MiniportSendPackets is not valid anymore. The call stack is: 8089a09c f7862394 NetMp!MpSendPackets+0x4d 8089a0c4 ba80cf47 NDIS!ndisMSendX+0x1e4 8089a0ec ba807df8 tcpip!ARPSendData+0x198 8089a114 ba80c632 tcpip!ARPTransmit+0x11a 8089a250 ba809357 tcpip!_IPTransmit+0x84f 8089a2f0 ba80954a tcpip!UDPSend+0x445 8089a314 ba8095b0 tcpip!TdiSendDatagram+0xd5 8089a34c ba80907a tcpip!UDPSendDatagram+0x4f 8089a368 8081dce5 tcpip!TCPDispatchInternalDeviceControl+0x10c 8089a37c ba7d3cf8 nt!IofCallDriver+0x45 8089a398 ba7d3b9b netbt!TdiSendDatagram+0x14e 8089a3dc ba7d3fad netbt!UdpSendDatagram+0x14c 8089a424 ba7e6411 netbt!UdpSendNSBcast+0x288 8089a460 ba7e6513 netbt!ReleaseNameOnNet+0xb8 8089a48c ba7de8a2 netbt!NameReleaseDone+0x58 8089a4a8 ba7e6273 netbt!InterlockedCallCompletion+0x3c 8089a4c4 ba7cf054 netbt!ReleaseCompletion+0x14e 8089a4e4 808316c0 netbt!TimerExpiry+0x5b Checking the miniport adapter states from the crash dump: kd> !miniport 8a0db130 Miniport 8a0db130 : BladeFrame Network Management Veth, v0.0 AdapterContext : 88319000 Flags : ac452008 BUS_MASTER, IGNORE_TOKEN_RING_ERRORS, DESERIALIZED RESOURCES_AVAILABLE, SUPPORTS_MEDIA_SENSE, DOES_NOT_DO_LOOPBACK MEDIA_CONNECTED, PM_HALTING, PnPFlags : 01c10000 RECEIVED_START, NDIS_WDM_DRIVER, SHUT_DOWN SHUTTING_DOWN, MiniportState : STATE_UNDEFINED IfIndex : 0 Ndis5MiniportInNdis6Mode : 0 InternalResetCount : 0000 MiniportResetCount : 0000 References : 3 UserModeOpenReferences: 0 PnPDeviceState : PNP_DEVICE_STARTED CurrentDevicePowerState : PowerDeviceD0 Miniport Open Block Queue: 87c88ea0: Protocol 8a0e6e48 = NDISUIO, ProtocolBindingContext 8a0ecf58, v5.0 87e5c8d0: Protocol 881a9e58 = TCPIP, ProtocolBindingContext 87cc6c38, v4.0 kd> !miniport 886bf680 Miniport 886bf680 : BladeFrame Network Veth0, v0.0 AdapterContext : 88665000 Flags : ac452008 BUS_MASTER, IGNORE_TOKEN_RING_ERRORS, DESERIALIZED RESOURCES_AVAILABLE, SUPPORTS_MEDIA_SENSE, DOES_NOT_DO_LOOPBACK MEDIA_CONNECTED, PM_HALTING, PnPFlags : 01c10000 RECEIVED_START, NDIS_WDM_DRIVER, SHUT_DOWN SHUTTING_DOWN, MiniportState : STATE_UNDEFINED IfIndex : 0 Ndis5MiniportInNdis6Mode : 0 InternalResetCount : 0000 MiniportResetCount : 0000 References : 3 UserModeOpenReferences: 0 PnPDeviceState : PNP_DEVICE_STARTED CurrentDevicePowerState : PowerDeviceD0 Miniport Open Block Queue: 8a176de0: Protocol 8a0e6e48 = NDISUIO, ProtocolBindingContext 87b26a28, v5.0 87cb2610: Protocol 881a9e58 = TCPIP, ProtocolBindingContext 87cb28e8, v4.0 I put flags in the driver and confirmed that both instances of the adapters had completed the MiniportShutdown routine.

I confirmed that under normal operation. Whenever MiniportSendPackets is called the TCPIP protocol reference count is 1+NumberOfPackets. That leads me to believe that our driver does not have any outstanding packets for the adapter when it returns from its MiniportShutdown routine. At that point all send packets are returned to NDIS and all receive packets have been returned from NDIS. (I confirmed that by checking the packet count of the allocated and returned receive packets.) Since MiniportSendPackets could be called or in process when a shutdown or adapter halt occurs we need to account for that. In the case of a shutdown we simply completes the packets. MpSendPacket also checks if the adapter can send packets. If a packet could not be sent and was not queued (e.g. the adapter is shutting down or is halted) then the packet is simply returned to NDIS. MiniportSendPackets does the following: VOID MiniportSendPackets (IN NDIS_HANDLE MiniportAdapterContext, IN PPNDIS_PACKET PacketArray, IN UINT NumberOfPackets) { PMY_ADAPTER Adapter = (PMY_ADAPTER)MiniportAdapterContext; UINT i; NDIS_STATUS Status = NDIS_STATUS_SUCCESS; PNDIS_PACKET pPacket; if (pGlobal->Flags & ADAPTER_SHUTDOWN) { if ((Adapter && Adapter->MpHandle) { IncRefCount(Adapter); for (i = 0; i < NumberOfPackets; i++) { pPacket = PacketArray[i]; NdisMSendComplete(Adapter->MpHandle, pPacket, NDIS_STATUS_ADAPTER_REMOVED); } DecRefCount(Adapter); } return; } // send packets IncRefCount(Adapter); for (i = 0; i < NumberOfPackets; i++) { pPacket = PacketArray[i]; Status = MpSendPacket(Adapter, pPacket); if (Status != NDIS_STATUS_PENDING) { NdisMSendComplete(Adapter->MpHandle Packet, NDIS_STATUS_SUCCESS); } } KeSetEvent (&pGlobal->WakePacketCompletionThreadEvent, IO_NO_INCREMENT, FALSE); DecRefCount(Adapter); } The problem is that in the case of a shutdown the MiniportAdapterContext pointer may not be valid anymore. The system crashes on the reference to Adapter->MpHandle. I donâ??t understand why NDIS is calling the Miniportâ??s send routine after it has shutdown the miniport. Should we in that case NOT call NdisMSendComplete, assuming that the system is shutting down anyway? Or do we have a bug in our driver caused by an outstanding packet or handle reference that is not reflected by the counters available through ndiskd? I went through the exercise and cleaned up all the miniport resources on shutdown (in contradiction to the DDK), but I still see the same problem: The MiniportSendPackets routine is called by NDIS after the MiniportShutdown routine has completed for the same adapter. And it does not matter if we have one or multiple adapters in the system. It may just take longer to reproduce the problem with just one adapter.

    - WDF and multi-function serial devices I am investigating how to use KMDF for a PCI Express card. The card can have multiple high speed UARTs. All N UARTs will share the same PCI memory BAR. The card will need to be supported under Windows 2000, XP and Vista. We already have a set of WDM drivers that work with an equivalent PCI cards. This set consists of a multifunction driver and UART driver. The multifunction driver (bus FDO) enumerates all of the UARTs and creates a number of UART PDOs. The UART driver uses a private interface (exposed by the multifunction driver) to obtain resources to be handled by each of the UARTs. The resources are not reassigned to UART driver; they are just handled by it. The old PCI resources are: 1) 1st memory BAR - 256 * N consecutive memory addresses (all UARTs in one PCI BAR). Handled by UART driver. 2) 2nd memory BAR - common interrupt status register (statuses for all UARTs). Handled by UART driver (but can easily be handled by the multifunction driver). 3) A single PCI interrupt - shared by all UARTs. Handled by UART driver (but can easily be handled by the multifunction driver). The old UART FDOs would connect to the shared interrupt only once. This way the interrupt latency is reduced: no multiple spin lock acquires/releases, and just a single interrupt status register read in order to dispatch interrupts to the appropriate UART FDOs. The new PCI Express resources are (the card is able to use MSI-X interrupts): 1) The same as above. 2) 2nd memory BAR - common interrupt status register (statuses for all UARTs). Used only if the system (OS or motherboard) doesn't support MSI-X, i.e. normally unused. 3) One MSI-X interrupt per UART. 4) One "old" PCI interrupt - Used only if the system (OS or motherboard) doesnâ??t support MSI-X; in this case shared by all UARTs, i.e. normally unused. In our new driver I would like to use a WDFINTERRUPT object, including EvtInterruptEnable() and EvtInterruptDisable(), for each UART since this would tie nicely with the WDF power management. What worries me is the following excerpt from the WDF documentation: "Your driver should create a framework interrupt object for each interrupt vector or MSI message that the device can support. If the PnP manager does not grant the device all of the interrupt resources that the device can support, the extra interrupt objects will not be used and their callback functions will not be called." My questions regarding this are: 1) It seems to me that with KMDF I actually have to reassign UART resources to the UART driver PDOs if I want to use WDFINTERRUPT objects. Is this correct? 2) If MSI-X interrupts are used, can I un-assign up to N PCI interrupt resources from the bus FDO in the multifunction driver's EvtDeviceFilterRemoveResourceRequirements(), and assign them to the UART PDOs (that reside on the bus newly created by the multifunction driver, and not on the PCI bus) in the multifunction driver's EvtDeviceResourceRequirementsQuery()? 3) In case MSI-X interrupts are not supported on a particular system, I guess I would have to un-assign the only interrupt from the bus FDO and then assign it to each UART PDO. So, un-assign once, assign up to N times. This would generate the correct number of WDFINTERRUPT objects, but then the latency would be unacceptable. I still need only one ISR to be called. Do you have any suggestions? 4) If I handle all the interrupts in the multifunction driver, it seems that I will lose all the power management related benefits of WDFINTERRUPT (on a per UART basis). Is this correct? 5) Is there any other way to handle this? I would really appreciate if you could help me with this as I am a bit stuck here. Thank you very much.

    - CreateFile performance I wrote an application dll and firewire 1394 driver. For sending data of any size (4 byte to 2048 bytes), application calls dll routine. In dll routine each time I open a handle to the driver (mostly non-overlap operations but few overlapped operations). Will it be useful if I open the handle to each device only once and keep using it. I can cache these handles and reuse them. Close device handle only if there is plug & play (device add or device removed) or when application is closed. Will it cause any new problems of synchronization with respect to pnp or cancel Irps that are queud at driver to receive incoming data. Will I see any overall improvement in performance when I am handling requests every 200 milliseconds. When I am receiving data, I receive more than one packet from driver to user mode. But I cannot send more than one packet because library function doesnot know how many applications are sending or how application will send or if there is next packet. I think CreateFile and CloseHandle() for every request is a performance hit because of user mode to kernel mode switches. Please advice if I should make the effort. hDevice = CreateFile( szDeviceName, GENERIC_WRITE | GENERIC_READ, FILE_SHARE_WRITE | FILE_SHARE_READ, NULL, OPEN_EXISTING, 0, NULL ); Tag: Multiple Report ID Problem Tag: 88030

So what happen i am able to get this much data on HOST side. Now for second test i assign 200Bytes buffer on my device side and i am doing stream anf want to get 400Bytes streaming at HOST side so host only able to read 200 Bytes and it comeout from the waiting mode. Actually i need 400 Bytes Streaming on HOST side so internally who is managing all this thing. Why it is not arising in 512 Bytes? I know what is BABBLE error. When device sends more data compare to HOST ask to device then this error will generate. If any one having any idea then please inform me.

    - routing dataout from AC97 codec to PCI driver in winxp Hai all, Can you please explain the data flow from an application(Windows media player) to ac97 codec and then to speaker. We have a PCI device which works in non DMA mode instead of speaker and we dont know how to integrate AC97 codec driver with our PCI driver. Can we use the existing adapter driver (WDM driver sample) to route the data from ac97 codec to our pci driver and how the pci driver knows the address used by the ac97 adapter driver for sending data to the speaker. Thanks in Advance. Tag: Multiple Report ID Problem Tag: 88012

    - express edition hi. I am planning to do some driver development using the DDK and the visual studio for c++ express edition. Has anyone done it before ? Are there any problems in this ? From the information on the net, it seems that only mobile applications cannot be done. The rest is all possible. Can someone shed some light on this ? Tag: Multiple Report ID Problem Tag: 88010

    - netrndis.inf problem When I tried to install NetChip RDK RNDIS sample in XP or Vista with MS's default netrndis.inf (only the device ID is changed), the installation wizard complained the line cannot be found in the INF. setupapi.log shows DIF_INSTALLDEVICE exit with 0xe0000102 error. NetChip's NcRndis.inf works fine in either case. I cannot see netrndis.inf has any problem. Can anyone shed light how to debug this problem ? Tag: Multiple Report ID Problem Tag: 88004

Hi All,
I have a HID keyboard application. I have single interface with one IN
endpoint EP1(IN) for keyboard and one OUT endpoint EP2(OUT) for
recieving data from the PC software.

I have modified the existing report descriptor with addition of a
vendor defined collection for output report descriptor as follows.

DESCRIPTOR MyRepDesc[L_F_KBD_REP] PROGMEM =

0x95, 0x06, // REPORT_COUNT(6)
0x91, 0x02, // OUTPUT (Data,Var,Abs)
0xC0 // END_COLLECTION

But its not enumarating ...whether i need to make any changes in my
report descriptor?
Thanks in Advance
