I see '#pragma INITCODE' used in example drivers.
I can not find a Microsoft source for information on it,

HidD_GetAttributes PROBLEM
I am trying to get the vendor ID of the USB HID devices currently
attached to the computer. I have the code I found in every place to do
this :
....
HidD_GetHidGuid(&GUID);
...
SetupDiGetClassDevs(&GUID, NULL, NULL,
DIGCF_PRESENT|DIGCF_INTERFACEDEVICE);
....
SetupDiEnumDeviceInterfaces(PnPHandle, NULL,
&GUID,Device,&DeviceInterfaceData);
....
SetupDiGetDeviceInterfaceDetail(PnPHandle, &DeviceInterfaceData, ...
....
HIDHandle = CreateFile(FunctionClassDeviceData.DevicePath,GENERIC_READ|GENERIC_WRITE,
FILE_SHARE_READ|FILE_SHARE_WRITE, &SecurityAttributes, OPEN_EXISTING,
0, NULL);
.....
Success = HidD_GetAttributes(HIDHandle, &HIDAttributes);
The first problem was SetupDiGetClassDevs with the GUID generated, I
solved this problem with
GUID = GUID_CLASS_USB_DEVICE;
But now my problem is with HidD_GetAttributes, this funtion never is
successful, always return 0
My OS is win 2000, the USB device I have connected is a USB flash
drive and I can see his vendor ID in the USBview.exe
Any idea?

MS PS/2 Mouse Driver Questions
(WinXPpro SP1)
I'm getting a lot of Event ID 256 warnings from the PlugPlay Manager.
The message is: Timed out sending notification of device interface
change to window of "MyTest". The consensus of what I've read is that
these warnings are caused by a device driver. The only clue in Device
Manager is a "device not responding" warning for a MS PS/2 Mouse --
because there is no MS mouse connected to the system. Instead, there is
a Logitech optical mouse (which also appears in DM) which works just
fine. I have searched the system for a file named "mytest.exe" but none
exists. There is no reference to "MyTest" in the registry. With that
background:
1. Can anyone confirm that the Microsoft PS/2 mouse driver for XP runs
a task called "MyTest"? If so, can this be prevented/turned off?
2. Alternatively, how can I uninstall this driver so I can see if the
warnings go away? When I try to uninstall from Device Manager, the
system automatically reinstalls the driver when I re-boot. Tag: Q: about ZwLoadDriver() Tag: 33272

HID USB Monitor
Hello,
I"m new to device driver development. I"ve gone through
DDK docs. I have an USB touch panel device which is HID
compliant, for which I want to write a driver. I"m
confused whether to write an USB driver along with HID
minidriver that talks with hidclass.sys OR to write a
mapper driver which map HID report and dispatch events to
mouseclass. My driver should also take care of pnp and
power. Any help in this regard will be really appreciated.
If you can direct me to any particular example DDK source
code in case to write a mapper driver.

assthru spinlock
I have compared the passthru example in WinXP SP1 DDK and
the Windows Server 2003 DDK. One major difference that I
have found is the use of a spinlock that was not present
in the previous sample. The lock is a member of the ADAPT
structure. I did not quite understand the purpose of the
spinlock, what data is it protecting, and what are the
race conditions it prevents?
I have 2 other related questions:
1. ADAPT_DECR_PENDING_SENDS also uses the spinlock. Won't
NdisInterlockedDecrement be more efficient?
2. In miniport.c I have seen the following code:
//
// If the miniport below is unbinding, just fail any
request
//
NdisAcquireSpinLock(&pAdapt->Lock);
if (pAdapt->UnbindingInProcess == TRUE)
{
NdisReleaseSpinLock(&pAdapt->Lock);
Status = NDIS_STATUS_FAILURE;
break;
}
NdisReleaseSpinLock(&pAdapt->Lock);
Why is there a spinlock here? No data is changed, only
compared.
Thank you. Tag: Q: about ZwLoadDriver() Tag: 33266
MiniportReset and connection status (NDIS test)
The MiniportReset test checks that connection state is restored after reset, and gives the driver
500 ms to restore connection ( script : 1c_reset.wsf, line 195 in ndistest 4.3.30).
What if this is not enough?
For wireless LAN, the same test suite allows up to 2 sec to connect
(script : 1c_wlan_associatetime.wsf ).
Does NDIS or any protocol actually expect the link up in 0.5 sec after reset?
Since MiniportReset does hardware reset, you can not expect reset time shorter than normal
connection (that is typically ~ 1 sec).
How do you cope with this issue? just skip hardware reset?
Any advice will be greatly appreciated. Thanks in advance.

WDM: Multiple instances of a device
Hello,
While writing a WDM video capture driver for a virtual non existing device
(based on the "testcap" sample in the DDK) I encountered a problem which I
can't crack. The driver is working ok but only one instance of the virtual
device can be used in the system. Which means that only one application can
use the virtual camera at any given time. If I want another application to
use the same driver I have to add one more virtual camera device, etc.
Please someone point me in the right direction where to dig to enable
multiple instances of the device driver.

Determining if PCI device is physically present...
OS: Windows 2K/XP
How does one programmatically determine if a PCI device (with a given device
and vendor ID) physically exists in a Windows 2K or XP system without
relying on a driver being installed?
I realize the PCI bus driver does the device enumeration and then drivers
are eventually loaded accordingly. In my case, I have to assume that a
driver may not yet be installed for a particular device. I obviously do not
wish to interact with it (until the driver is installed), but is there a way
to "ask" the bus driver if it has seen the PCI vendor/device ID on the last
PCI scan?
Most of what I have found in Windows programming documentation assumes that
a driver already exists, a device interface has been registered, etc.
I would be interested in either a user-mode or kernel-mode solution to this
problem. Preferably a user-mode solution. But I do have a kernel driver
(that is guaranteed to exist) that I can communicate with and modify if
necessary.
Thanks in advance.

Paral Port Mode in BIOS vs parport driver.
Hello,
I am trying to use Windows' standard parallel port
driver( parport ) API from within my driver for
test purposes.
This is what I do:
1) using the name "\Device\ParallelPort0" and
IoGetDeviceObjectPointer(), I get Device Object
of the parport.
2) Then I build a device io req using
IOCTL_INTERNAL_GET_PARALLEL_PNP_INFO and
IoBuildDeviceIoControlRequest API.
3) Then I call IoCallDriver().
I get success and the returned PARALLEL_PNP_INFORMATION
struct's "HardwareCapabilities" field describes the
capabilities of the Parallel Port H/W.
My PC's BIOS Offers: AT, PS/2, EPP and ECP as options
for the parallel port. But when I check
the "HardwareCapabilities" field which is a bit mask of
various possible modes, I only see ECP capability, This
field never shows EPP capability in this field of
PARALLEL_PNP_INFORMATION structure.
Why does paport show fewer capabilities? Can someone help?

Intercepting IRP_MJ_READ/WRITE
Hi all,
Still playing with the FILESPY sample from IFS kit. What I am trying to
do now is access the buffers associated with each IRP_MJ_READ/WRITE.
Obviously the filespy sample shows how to intercept every filesystem IRP,
but
not how to access the buffers.
What I need to do is copy the contents of every buffer into an area of
non-paged-pool, each time one of these IRPs completes. So my question is,
what is the safest way to do this?
My concerns are:
what type of I/O is being performed (buffered/direct/neither)
what IRQL the IRPs complete at (presumably dispatch-level)
are the buffers still valid at this time etc.
The filespy sample demonstrates how to "synchronise" the completion
of IRP_MJ_CREATE (plus a couple of others) back to PASSIVE_LEVEL,
it does this by waiting on an event in the dispatch routine which is
signalled
by the completion routine. Should I use this mechanism to ensure that
IRP_MJ_READ/WRITE have completed at passive_level before accessing their
buffers?
What do I do when I have done this - do I need to lock pages into memory
etc??
I need some pointers I'm afraid, still struggling to understand this stuff..

64-bit PCI mem xfer resolved
For those of you who remember my 64-bit delima ...
I't looks like my PCI bridge chip, Intel's P64H2, has a
FIFO with a high-water mark. When I hit this mark with a
quadword alligned address, the bridge makes the decision
to assert REQ64#.
I blasted this FIFO in a loop. After enough transfers,
the bridge asserted REQ64# and my PCI card responded with
ACK64#.
It looks like a single 64-bit PCI memory transfer is not a
function of software (Bridge is master).
If you want 64-bit, your PCI card needs to perform the bus
mastering. Tag: Q: about ZwLoadDriver() Tag: 33226

Queued spinlock mystery !!!

I don't understand how queuedspinlocks works anymore. I
thought that there
was only one queue and all cpus were locking themselve
with that queue ex:
KLOCK_QUEUE_HANDLE

| Acquire lock | <----- cpu #0
----------------
----------------
| Acquire lock | <----- cpu #2
----------------
----------------
| Acquire lock | <----- cpu #1
----------------
----------------
| Acquire lock | <----- cpu #3
----------------
If this is not the case but every cpu must have his
KLOCK_QUEUE_HANDLE how
can cpu #2 knows that it must wait because cpu 0 have the
lock if this
lock was putted into the KLOCK_QUEUE_HANDLE of cpu #0 ?

but in Windows 2003 Server, if the port is TCP or IR the
job number is not used in the file name, and the .SHD file
is locked.
I'm wondering there is some hidden API in local print
provider to get the name.
Thanks in advance,
