USB driver for Bulk Devices
I am using the USB driver for bulk devices given by
Microsoft that comes along with NTDDK. The name is
BulkUSB.sys.
Question 1. Does that support multiple devices
Question2.
I plug in a bulk transfer device. The device is detected
by windows. When I plug out the device, the plug and play
manager pops up notifying of the unsafe removal.
In another case I plug in two or more of such devices.
And when I plug out or try to do a safe removal from the
plug and play manager, windows crashes.. or I'm shown a
blue screen.
Is there any fix for the driver. Or Is there any
modification that needs to be done in the driver sample.

How to expose new device nodes
Hi All
I have to write a usbccgp.sys like driver ie which
exposes new device nodes for a composite usb device ie we
have to assign a separate PDO to each function of a
composite device.
How do I proceed ?
Thanks in advance

Check Irp->PendingReturned in IoComplete routine
In IoComplete routine, sometimes it check Irp->PendingReturned
and call IoMarkIrpPending if the flag is set.
Is there any rule for this?
According to DDK document, it says....
=================================================================
Any driver that sets an IoCompletion routine in an IRP and then passes
the IRP down to a lower driver should check the IRP->PendingReturned
flag in the IoCompletion routine. If the flag is set, the IoCompletion
routine
must call IoMarkIrpPending with the IRP. Note, however, that a driver that
passes down the IRP and then waits on an event should not mark the IRP
pending.
=================================================================
However, bulk usb sample code in DDK.
In IoComplete routine of set device power up, FinishDevPoUpIrp, it checks
Irp->PendingReturned and call IoMarkIrpPending if flag is set.
In IoComplete routine of set device power down, FinishDevPoDnIrp, it doesn't
check this flag. Why???
Does it have something to do with IoCompete's return value?
Best Regards

FakeModem sample
Hello,
Does anyone have any experience with the FakeModem sample?
I wanted to start experimenting with a modem driver and I thought I would try compiling and playing with the FakeModem example found in C:\WINDDK\2600.1106\src\network\modem\fakemodem. I made no changes to the code, just compiled and installed. I then fired up HyperTerminal--and nothing. Not a thing.
Are there any other modem samples somewhere that I could look at?
Thanks

Firmware files location
My driver need to write the hardware firmware files every time it starts.
The files are a bit big ~100K uncompressed and ~60K compressed.
Where should my INF file store these files?
We prefer not to couple the firmware files with the driver since the driver
might manage different versions of the firmware.

GDI_DRIVER Driver compilation with VS7.1 IDE
Hi,
Introduction:
**********
I am writing a display mirror driver, I am trying to use the VS7.1 (.NET)
IDE to compile the driver, conversion to an .vsproj solution is done by the
'Source to DSP converter' app provided with 'SoftIce driver suit'.
The Problem:
**********
The mirror is build of to files: the miniport driver and the display driver,
no problems has occurred converting compiling and using the miniport driver,
in contrast, conversion of the display driver failed: the 'Source to DSP
converter' doesn't support GDI_DRIVER conversions, SO..., I tried to do some
tricks: I have changed the TARGETTYPE of the GDI_DRIVER to DRIVER and then
used the 'Source to DSP converter' with the new source file, the result was
a new .vsproj compiling a .sys driver I have changed the name of the driver
to be .dll and removed the 'DriverEntry' DLL entry point from the project
configuration, still, using the new driver causes an 'Unhandled kernel mode
exception', using the display driver compiled by the 'source' makefile works
fine and doesn't reproduce this problem, what may cause the problem? what
went wrong during the 'Source to DSP converter' conversion? what special
configurations are required for a GDI driver?
Should there be any specific entry point to a GDI_DRIVER?
Thanks in advance,

PNP Manager
I have developed a failover driver for a fibre channel
medium changer device on Windows 2000 that is tightly
dependent on the PNP Manager. When I pull the cable out
of my hardware, one of my Win/2K systems immediately
rescans the bus without any intervention on my part,
notifies Device Manager of a hardware change, and sends
IRP_MN_SURPISE_REMOVAL to my driver.
I have another Windows system on which the rescan does
not automatically take place. On that system I have to
use device manager to manually "Scan for hardware
changes" before the surprise removal notification will
happen.
In order for this driver to work, the scan needs to
happen automatically. How do I get this to happen? Does
it depend on Windows or on the fibre channel adapter card
and its driver? Tag: switch on the parallel port's ECP Mode within a Printer UNIDRV Tag: 38462

HCT 11.2 - TestImports Problem
Can someone help me understand what this error means:
ERROR: 71: Public Imports Test failed to run, TestImports function call

This is from a run of HCT with an NDIS IM driver. What's odd is the NDISTEST

calls from an NDIS driver).
Also, the driver is not binary compatible (it's only used for XP). Would
that cause this problem. Tag: switch on the parallel port's ECP Mode within a Printer UNIDRV Tag: 38439

Audio synchronization
I need to synchronize audio with another output device.
Can I do this with an interrupt driven heartbeat generated
by the output device. The synchronization only needs to
be visually accurate, in other words I'm not concerned
about microseconds, but I would like to be accurate to 100
milliseconds.
My initial thought is to have my interrupt routine begin a
100ms segment of audio. The next interrupt would stop the
previous segment (if the audio is behind) and then play
the next segment. My "interrupt routine" would probably
be a thread at the application level waiting for my device
to interrupt. I don't think I would need to place this in
my device's DPC.
I've been reading up on the Wavform Audio Interface, is
this the correct area? There must be some support for
this built into the interface to facilitate the usage of a
scroll bar to scan through an audio file. My questions
are, am I looking in the right place and a corrollary, how
flexible is the interface? I don't want to waste research
time going down a false path.

Error USBD_STATUS_ISO_NOT_ACCESSED_BY_HW
Hello:
What is the meaning and cause of usb packet error
USBD_STATUS_ISO_NOT_ACCESSED_BY_HW (code 0xC0020000)
returned by urb->UrbIsochronousTransfer.IsoPacket
[PacketNumber].Status? I am getting this error
occasionally (a few percent of all packets) when
streaming bidirectional (1 stream out, 1 stream in,
simultaneously using 2 alternating urbs for outgoing and
2 for incoming) high speed usb 2.0 isochronous data to a
custom hardware device. I am using 16 microframe urbs
and the error always occurs on microframes 1, 2, and
sometimes 3 of the 16 that are being transferred. All
microframes before and after this complete normally. It
affects both read and write urbs. OS is WinXp SP1 with
USB patch. Usb.h states that "for some reason the
controller did not access the TD asocated with this
packet" as explanation for this error.
Thanks Doug Tag: switch on the parallel port's ECP Mode within a Printer UNIDRV Tag: 38405
I refuse to believe this....
When installing a printer driver, Add-Printer etc etc, it prompts me for a
printer name just before finishing the installation.
I have two printer models, but would like to use the same printer name..
without having to manually enter it.
Is there really no way that I in my INF file can provide a default printer
name ?
TIA

Device Object NULL in completion routine
Hi,
In my FSD filter, I am building up my own IRP to send to the
lower driver so that I can get some info (QueryDirectory)
about a directory. The problem is that when my completion
routine is called, it contains proper data, but the device object
I get is NULL (is this normal?). Also my stack location seems to be wrong
since it no longer contains the parameters (minor/major functions say),
that I setup.
Any clues?
TIA,

Maximum StrMini Driver Size??
I am developing a stream class mini driver based on usbcamd. Today I ran
into an extremely odd BSOD that I initially thought was related to some
memory management code that I had added. It turns out that the problem is
that I added code. I have reached the state where the following will take
the driver from functional to non-functional.
int i
for(i=0;i<1;++i){}
I can add this, or equally useless code in a variety of different functions
(none of which are called) and cause this error. The BSOD message is about
a page fault in the non-paged area caused by ks.sys. It occurs when I
attempt to render the capture pin on the filter. The driver can be loaded
and unloaded as many times as one likes without error.
I am wondering if this can be related to SRB_PAGING_OUT_DRIVER? I noticed
that the INF file (intelcam) I copied does set PageOutWhenUnopened registry
setting. Is it possible that enabling this can cause this error or is there
some other possibility?
This is running on XP Pro SP1.

Sound Capture
Hi, I have a problem.... actually it is a thing to do on my list, and I
wondering if anyone can give me a hint or two on where to look for tackling
it.
Well, all I need to do is to intercept and capture sound (wav or raw doesn't
matter) that only a certain application generates opposed to whole system
(all apps.).
The app. uses none of the fancy directx stuff, just plain win32 APIs (MCI I
think)
Any thought on how should I begin looking for this solution?

Device Extension for NDIS miniport driver
I am writing a NDIS miniport driver. From DDK
documentation, I was told to use NdisRegisterDevice
instead of IoCreateDevice to create a device object.
However, the same documentation also says that the device
extension for an object created with NdisMRegisterDevice
is reserved for use by NDIS and cannot be used by the
driver. I want to modify the device extension to store any
state status and information. How can I do that?

SetupCopyOEMInf - avoiding prompts during install
I have a new driver install and an old driver install that use different
source media locations. I have been using SPOST_PATH for the
OEMSourceMediaType when I call SetupCopyOEMInf. This is leading to setup
problems because the old INF is selected by SetupAPI during install. This
INF points to an installation directory that does not exist and the user is
prompted for the correct location of required files.
I think the root of this problem is that the PNF has to old source media
information. Should I call SetupCopyOEMInf with SP_COPY_REPLACEONLY copy
style to update the old PNF if it exists and then call it again with the
SP_COPY_NOOVERWRITE copy style to copy it sure the PNF has the current
source path info (if needed)?

Hardware ID in win 2000 and UpdateDriverForPNP
My .inf has an entry for that says _01
%xyz.DeviceDesc%=xyz.Device,USB\VID_xxx&PID_yyy
I am trying to install the driver for the device for the case where
the device is plugged in but the Add New hardware wizard was cancelled
by the user.
Now, if I pass the HWID "USB\\VID_xxx&PID_yyy", updateDriverfor..
fails with 20B (no_such_device) I think.
Then if I change it to "USB\\VID_xxx&PID_yyy&Rev_0001" (which I know
from the registry whenever I install this successfully in the nice ol'
plug device after software installation way) AND also change it in
.INF, my updatedriver.. succeeds and device is shown working properly
with the correct name in device manager.
So my question is, what is that Rev.. thing? is it like a hardware
revision? if so, I would not know every possible revision number in
advance and would like to keep it generic for the device? How do I
achieve that? What is the correct entry in .INF and correct HardwareID
to be passed to the function updatedriver..
