list of all the installed devices

[John Smith]

i want to get the list of the installed devices on a machine. I only need
the pci, ide and scsi (maybe usb) devices installed on the box. I was looked
thru WMI and Win32_SystemDriver but was unable to find a way to filter the
results for just those things...

can someone point me right direction?? maybe i am missing something in
Win32_* can will do what i am looking for...

-thankz

John,

You will want to check out the following WMI classes:

Win32_USBControllerDevice
Win32_SCSIControllerDevice
Win32_IDEControllerDevice

I can't find anything for the PCI slots, but I am sure there is
something in there.

The classes listed above should give you the items that are connected to
these controllers.

Hope this helps.

thankz for the reply Nicholas...

ok this is what i am trying....
[Code lang="C#"]
ObjectQuery oq =
new System.Management.ObjectQuery("SELECT * FROM
Win32_IDEControllerDevice");
ManagementObjectSearcher query =
new ManagementObjectSearcher(oq);
ManagementObjectCollection queryCollection = query.Get();

foreach ( ManagementObject mo in queryCollection)
{
Console.WriteLine("Antecedent : "+mo["Antecedent"]);
Console.WriteLine("Dependant : "+mo["Dependent"]);
}
[/Code]

now the "Dependent" is a CIM_LogicalDevice reference, how do i get the value
for its(CIM_LogicalDevice) properities like "Caption" and all the other
good stuff ...

[Output]
Antecedent :
\\JAGERMEISTER\root\cimv2:Win32_IDEController.DeviceID="PCI\\VEN_8086&DEV_24

John,

You should be able to access it like any other property, like this:

foreach ( ManagementObject mo in queryCollection)
{
Console.WriteLine("Antecedent : "+mo["Antecedent"]);
Console.WriteLine("Dependant : "+mo["Dependent"]);

Console.WriteLine("Caption : "+mo["Caption"]);
}

It should work.

John,

I checked the Win32_IDEControllerDevice WMI class, and there is no
Caption property on it, or anywhere on the heiarchy tree.

i know that thats y i said..

>now the "Dependent" is a CIM_LogicalDevice reference, how do i get the

the caption property is for the CIM_LogicalDevice (link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/
cim_logicaldevice.asp )... and since the "dependent" property is a reference
to that class, there is should be a way to get the caption property for the
dependent property

John,

If the property is returning a string, you can perform a query of all
instances of CIM_LogicalDevice where the DeviceID is equal to the Dependent
property.

There is no deviceid property for Win32_IDEControllerDevice... so it just
gives me a invalid query error....

the deviceID property is only for the CIM_LogicalDevice which i can't seem
to get too..

but maybe i am missing something... can u give me a code example...

thankz for all the quick replies...

John,

It's like a join between two database tables. The Dependent property is
returning an id (foreign key) which corresponds to the DeviceID property on
instances of CIM_LogicalDevice (the primary key). So you have to formulate
a new query that will select the appropriate instances from
CIM_LogicalDevice where the DeviceID is whatever the Dependent is, like
this:

select * from CIM_LogicalDevice where DeviceID = <Dependent>

I tried Selecting from USBControlerDevice, but it only gives me installed devices.

How do I get the following info:
1) Is currently connected to PC?
2) Friendly name (i.e. Apple iPod Touch, Sansa Clip etc.)
