Parsing devices from setup classes
in [Device Drivers]
|
From: santapanda on 13 Apr 2010 15:46 Hello, I'm developing a program to find certain devices. In some cases, I'm looking for the program to find *any* device in the setup class. In other cases, I only want pay attention to some of the devices in the setup class. For instance, the Net setup class contains both ethernet adapters as well as wireless ones; my application is only concerned with Wireless and should ignore ethernet adapters. I've run Devcon on a few different machines to determine if there is a rhyme or reason to how I should isolate some devices. I haven't found a consistent pattern in instance IDs or hardware IDs that would make it easier to isolate the desired devices. Am I missing something; does anyone have ideas on how, once within a collection of devices from a setup class, I can easily pull out the ones I want? Thanks!
From: Doron Holan [MSFT] on 13 Apr 2010 18:46 device classses are not that interesting, it is a UI grouping feature. if you are filtering on functionality, device interfaces are closer to what you want to list. BUT that is still not the entire answer, because many types of devices may be under the same device interface GUID. for instance, in the net example you list, wireless NICs and wired NICs expose the same dev interface d -- This posting is provided "AS IS" with no warranties, and confers no rights.

From: santapanda on 14 Apr 2010 09:30 Thanks Doron for your response, I had planned on using the interface classes for when I needed to alter the status of the devices (enable/disable). But where does this leave me with distinguishing between the different devices in the classes?

From: Doron Holan [MSFT] on 15 Apr 2010 13:44 it is device interface specific how to differentiate. I am pretty sure there are some netcfg APIs that will help, I don't know what they are though d -- This posting is provided "AS IS" with no warranties, and confers no rights.

From: santapanda on 28 Apr 2010 12:55 I found that for network cards, I can use WMI objects available in C#. By using the System.Management namespace, I can query Win32 classes such as Win32_NetworkAdapter. That particular class has a property on it, AdapterType, which differentiates between the different types of network adapters. Pretty cool!
