Unable to Pend IRP on ISO Read (IN) pipe

    I need to pend an IRP on the ISO IN pipe with a completion routine, which
    will get invoked when the driver below (USB) has some data on the pipe. My
    problem is that i have been unable to pend an IRP (Created using
    IoAllocateIrp) on the ISO read (IN) pipe. I have tried with the sample
    provided in DDK (\WinDDK\6000\src\usb\isousb\sys) as well as the sample
    provided by Walter Oney (\Samples\Chap12\usbiso\sys).

    I am using the alternate setting number 5 provide by my device on interface
    1, wherein the maximum packet size is 0x33 (51) bytes.

    Whenever i call to IoCallDriver to send the IRP to the next driver below, i
    get a failure with code 0xC000000D(STATUS_INVALID_PARAMETER). If at all the
    call returns STATUS_PENDING, the completion routine for the sub IRP's is
    getting called.

    Any help in this regard will be great.

    Thanks in advance.
