Hi all,

I got handle of my USB disk using following instruction.
handle = CreateFile(dev_name, 0, 0, NULL, OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL, NULL);

I am getting this handle successfully. The problem I was facing previously
was that my ISR was not getting invoked on attaching USB disk. What I did, I
checked the registry values and found out that I was passing wrong GUID in
notification filter. Just to tell you I was passing {0xc5e4c602, 0xa413,
0x4caa, {0x9b, 0xbd, 0x2e, 0x35, 0x4c, 0x1b, 0xdd, 0xfc}} which was not
working.

I then had to look in registery that when I plug in my device it is
registered at some other Interface GUID which is {0xa5dcbf10, 0x6530, 0x11d2,
{0x90, 0x1f, 0x00, 0xc0, 0x4f, 0xb9, 0x51, 0xed}}.

Now when I set this value in notification filter and then pass this
notification filter to RegisterDeviceNotification I get ISR invoked
successfully.

But now the problem is that when I call DeviceIoControl method as shown
below it returns error. I've checked the error code and it is returning error
number 87 which means invalid parameter. code snippet is below

unsigned int usb_get_last_status(libusb_usb_dev_handle *dev)
{
usb_context_t ctx;
unsigned int ret = 0;
DWORD err = 0;
unsigned int status = 0xfffffffe;

memset(&ctx, 0, sizeof(usb_context_t));
ctx.dev = dev;
ctx.control_code = LIBUSB_IOCTL_USBD_STATUS_READ;
ctx.ol.Offset = 0;
ctx.ol.OffsetHigh = 0;
ctx.ol.hEvent = CreateEvent(NULL, TRUE, FALSE, NULL);

if(ctx.ol.hEvent)
{
ResetEvent(ctx.ol.hEvent);
if(!DeviceIoControl(ctx.dev->impl_info,
ctx.control_code,&ctx.req,sizeof(ctx.req),
&status,
sizeof(status),
&ret,
&ctx.ol))
{
err = GetLastError();
}

..........................
Can anyone tell me the reason of it and any solution to the problem?

I have no idea what that GUID is. Is it some sort of libusb device
interface? If so, maybe that explains why your IOCTL is failing --
libusb isn't really loaded, because you're not getting the device
interface arrival.

This is registered by the USB stack for all USB devices. It's not
native to USB disk drives.

I'm not familiar with how libusb works, but something tells me you
might not be able to send a libusb IOCTL to a USB drive which already
has a driver loaded for it (usbstor).

Will not work on x64 Vista/2008, also note that NtReadFile hook will not catch
paging IO.

Using a SSDT hook driver for this is incredibly irresponsible. First as Max
pointed out, it will not work for X64, and it will not catch paging I/O.
Also, getting these right is harder than one thinks, and is likely to
destabilize the system. Also, the driver will immediately be flagged as
MALWARE. Following such a path for file operations that are easily
catchable with approved ways, is beyond stupid.

You maybe need a SSDT hook driver. You can hook some native API such
as NtCreateFile, NtWriteFile and NtReadFile.
I think it can do this case. :)

This is normal, buffer pools are non-op in NT, they were only used in Win9x/Me.

In NT, NDIS_BUFFER is MDL, NdisAllocateBuffer is
IoAllocateMdl+MmBuildMdlForNonPagedPool, and NdisFreeBuffer is IoFreeMdl.

TOPIC: Cannot capture Audio in AMCap

Hi All

I have written pin-centric avstream based driver, I can successfully
preview both the audio and video. The capture of the video was also
successful. but iam unable to capture audio through AmCap, The graph
is as follows

avstream based capture filter (Audio pin) ----->Smart Tee(capture
pin)----->AVI MUX -->file writer
avstream based capture filter (Video pin) ----->2nd Smart Tee(capture
pin)----->AVI MUX->file writer

When I drag and drop the captured file in the graphedit tool, the avi
file gets connected to the avi splitter, the avi splitter shows audio
and video pins, the video gets connected to the umedia video decoder
and gets rendered properly. Similarly the audio gets connected to the
umedia audio decoder and gets rendered properly. When I try to play it
I get a black screen for the video.

However when I connect the avi file to the uMedia Demux, it recognises
it as the H.264 format data and plays the video only successfully.

Can someone tell me what could be the issue.

Please let me know if this is the timestamp issue in the driver or
someother issue.

The process function of my driver is something like this, which fills
the timestamp value to the frames.

NTSTATUS

PAGED_CODE();
