Hi buffering83,

You can install a an on-demand loading driver by defining the start type as SERVICE_DEMAND_START.

What Determines When a Driver Is Loaded[^]

This corresponds to the following i8042prt.sys registry key as an example:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\i8042prt\Start

You can browse your registry and see how other device drivers are loaded by looking at the Start key. Based on your previous questions here on codeproject however you seem to be developing a filter driver. Filter drivers typically belong to a load order group:

Load Order Groups for File System Filter Drivers[^]

The load order groups correspond with the registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ServiceGroupOrder\List

i have question about USB Filter Driver~ [modified]

i made usb filter driver and install it in the
"class regedit: 36FC9E60-C465-11CF-8056-444553540000"

so i checked that my filter driver is upperfilter.

i want to control storage usb not mouse or keybord usb.

and so i think that i can do control this when ioManager make irp_mn_start_device.

but my filter driver received all irps related about usb(keybord, mouse)

and i wnat to check only storage usb.

so can i know what kind of usb? by using flag or something?

//////////////////////////////////////////////////////////////////////

i mean that i want to check what is MOUSE USB or KEYBORD USB when irp_mn_start_device.

Hi buffering83,

You have compiled a sample USB class filter driver. So quite naturally you are going to recieve IRP from all types of USB devices connected to the device class. Here is a diagram of USB mass storage device stack:

What are your driver requirements? What are you trying to accomplish?

i want to make USB control a program that

decide to approve USB storage.

when you insert USB Driver to pc, There is pop-up message which is asking you code.

if code is correct , your usb can be used.

but code is not correct , your usb can be terminated by device driver.

i make my usb filter driver, but i don't know how am i check .

i want to control only storage usb driver.

if you let me know your e-mail, i can send you my usb filter driver.

thank you for answering my question.

have a good day.

Normally I do not correct the english of non-native speakers but your misuse of blow might get you in trouble as this word has several slang definitions[^]. I believe the correct english word you are looking for is below[^].

Now lets address your question:

When you install a device the operating system identifies what type of device you are installing by using the Class GUID. Microsoft Windows defines many device setup classes:

System-Supplied Device Setup Classes[^]

If you open regedit you can navigate to the key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}

Under that key you will find the value UpperFilters.

The simple answer to your question is that the following lines in your INF:

[HajeSample.HW.AddReg] 
HKR,,"UpperFilters",0x00010000,"MOUFLT"

These INF lines when installed will instruct the operating system to load the device driver as an Upper Level Filter Driver[^] for the mouse device class.

//as you can see INF file.

"MOUFLT driver is located between mouclass and i8042prt"

but i don't know how can i know that MOUFLT can be located between mouclass and i8042prt.

That INF file just show

Hi buffering83,

On your motherboard you have an 8042 microcontroller[^] and i8042prt.sys can read/write to this microcontoller using ports 0x60 and 0x64 available through the BIOS. This is essentially the PS/2 controller[^] to which a keyboard/mouse may be connected.

When you boot your computer your BIOS discovers the PS2 contoller and assigns IRQ1 and reserves ports 0x60 and 0x64 for the controller. When you boot your Windows operating system the Microsoft Plug and Play Manager[^] discovers through ACPI calls[^] that your computer has a PS2 contoller and will assign ACPI/PNP0303 and/or ACPI/PNP0F03 port drivers which is by default in your registry as i8042prt.sys You can search for the string PNP0303 or PNP0F13 and find the i8042 ACPI PNP driver entries.Note: This is an incomplete, very brief description of BIOS PnP/ACPI interaction.

buffering83 wrote:

The INF files may not contain any reference to mouclass or i8042prt. Your mouse filter driver is only concerned with GUID of the device class. Perhaps a visual representation will help you understand:

Have a look at the following diagram:
Types of WDM Drivers[^]

A more accurate description of your device stack is something like:

[Your Upper Filter]<--------------------+
					|
					|
[i8042 Function Driver] <-----> [Mouse Class Driver]
	|
	|
[Lower Filter]
	|
	|
[ACPI Root Bus Driver]
	|
	|
[Hardware Abstraction Layer]
	|
	|
[8042 microcontroller]

Your filter driver is designed to filter an entire device class. In other words... Your upper filter will filter anything that describes itself as a mouse.

i want to make usb filter driver.

but i can't find how am i make...

some book just modify regedit file, and other book explan by using inf file.
(of course that book just show simple not detail.)

what i want to is

when insert USB to usb port , some application(which make me) know about this insertion and pop up some message box.

so i think that first i have to do is make simple usb filter driver and insert usb filter driver to device stack.

but i don't know how can do it.

If your requirements are to simply detect insertion/removal of a USB device you can simply handle the WM_DEVICECHANGE Message[^] and the DBT_DEVICEARRIVAL Event[^]

Here are some samples of its usage:

From ring0/kernelmode you can use the IoRegisterPlugPlayNotification[^] to register a callback. You need to register for a PnP Notification[^].

Hello,

I am new here and I have a question. I am using c# express edition, and I want make an application that can use my internal gps module from my nokia n82 by USB connection or by bluetooth connection(My pc has a bluetooth ability and my phone also) . Is this even possible? And if this is possible can anyone give me a short step by step plan. I am really curious if it is possible to interface with my Nokia N82 gps module and get gps coordinates and very eager to use this in my application.

Thanks for any reply

Access denied opening raw pdo

Hi,

I'm trying to set up raw pdo and i'm basing myself on the kbfilter example.

I used the code on the sample to put it on my device driver based on the hidfx2usb sample.

However, when I tried to open the raw pdo thru its guid I have an access denied.

How can i debug such error? How can I know why is it having an access denied?

Any tips?

Thanks,

Nuno

Raw PDO... how to make it associated correctly with a device

sinosoidal29-Jul-09 6:49

29-Jul-09 6:49

Hi,

I'm trying to setup a Raw PDO. I'm trying to do this because i'm writing a driver which is based on the hidfx2usb sample and it maps the usb device into a hid device.

the thing is that i can't access directly the device from the user space because the hid class blocks the requests.

i've been told to create a raw pdo device to have direct access to the device.
i had a look to kbfiltr and there is created a pdo, but the example registers a pdo for a keyboard and my device is a usb device.

my question is about how to associate the pdo to the usb device.

in the example the base string for the pdo registering is this:

#define KBFILTR_DEVICE_ID L"{A65C87F9-BE02-4ed9-92EC-012D416169FA}\\KeyboardFilter\0"

How should I register a pdo for a usb device?

Thanks,

Nuno

When the framework creates a device object, it always sets the FILE_DEVICE_SECURE_OPEN flag so that the operating system will check a device's security descriptor before allowing an application to access any names within the device's namespace.

USB mass production each with their own serial number

Hypermommy28-Jul-09 8:59

Hypermommy

28-Jul-09 8:59

We're getting close to being finished with this program I've been writing. Now it's almost time to go to production. For production we need to copy my program and database to a USB stick, pull the next available serial number from an Excel spreadsheet (or another database), open the database on the USB stick and record the serial number there and in the Excel spreadsheet.

Simple, simple code, right? Yeah... until we think about the fact that we're going to be mass producing these USB sticks several at a time. I know the first order is for like several hundred so there's definitely not time for someone to sit there and do this one stick at a time.

However, I can't imagine that this is something new. There has to be some combination of hardware/software out there that will not only copy the files to the USB stick (we've found several of those) but also allow us to put a unique identifier on each stick. Ideally I'd like to be able to put the serial number in the database but if it's a text file or some other file format that would probably work too as long as I can figure out how to access the number because it has to be something that my program can show the user.

Help? Ideas? Thanks!!!
