Reading Device Manager's Property Fields in Windows 7/8 - windows

Question

I am developing a windows application which gives the field details --> X.
Where X is -->
Right Click My Computer >
Properties >
Device Manager > (select any Item - Say KeyBoard) >
Click it > standard PS/2 KeyBoard >
double Click standard PS/2 KeyBoard >
click the Details Tab >
Under the Property there are various fields like Display Name , Problem Code,Parent Siblings, etc , etc?
I want to get their values .
Which Windows API I can use for this.
I am doing this for windows 7 as well as windows 8.I hope the API will remain the same.Also i am having 64 bit machine.
This has to be true for any device whose details I wanted to know from the Device Manager.
ALso I just want to all operations - Reading and No Set (writing) so I think I will not be having any problem with violating the Admin Rights.PLease suggest.! I have added Snapshots for reference!Say for example I want to know the current State of the HID USB Complaint Mouse(D0(Active) or D2(Sleep)).
I need to Get this Power State D0.

Answer 1

The question is tagged with C#, though the actual question asks for any Window API. With the Win32 API the information can be retrieved with SetupDiGetDeviceRegistryProperty(). The steps would be:
Get a device info set for the devices you're interested in via SetupDiGetClassDevs().
Iterate through the device infos via SetupDiEnumDeviceInfo().
Get the properties via calls to SetupDiGetDeviceRegistryProperty().
Destroy the device info set via SetupDiDestroyDeviceInfoList().
According to the documentation the API is available on Windows 2000 and later.

It's quite easy to get the hardware information using ManagementObjectCollection.
For instance to get all properties and values from the PC processor
var win32DeviceClassName = "win32_processor";
var query = string.Format("select * from {0}", win32DeviceClassName);
using (var searcher = new ManagementObjectSearcher(query))
{
ManagementObjectCollection objectCollection = searcher.Get();
foreach (ManagementBaseObject managementBaseObject in objectCollection)
{
foreach (PropertyData propertyData in managementBaseObject.Properties)
{
Console.WriteLine("Property: {0}, Value: {1}", propertyData.Name, propertyData.Value);
}
}
}
The full list of WIN32 class name is available at http://msdn.microsoft.com/en-us/library/aa394084%28v=VS.85%29.aspx

You're going to have the easiest time (I think) doing this with PowerShell. If you are writing some C# code you can execute a PS script using types in the System.Management.Automation namespace, such as PowerShell (link: http://msdn.microsoft.com/en-us/library/system.management.automation.powershell(v=vs.85).aspx) but I would begin your testing using the PS Console.
You should first (using PowerShell) explore the WMI objects in your environments using this command
Get-WmiObject -List -namespace root\CIMV2
Then once you identify with class you are looking for you can retrieve details on that class using this command:
Get-WmiObject -namespace root\CIMV2 -class Win32_USBControllerDevice
Once you have that content you'd have to parse the text.
UPDATE: Try using this command to get the "State", "Status", and "Started" attributes of mouse drivers on your PC:
gwmi Win32_SystemDriver | where {$_.DisplayName -like "*Mouse*"}
