Detect Errored Devices on Windows XP with C#/pInvoke -

-

How do you ask the status of all known devices?

Where device is USB connected hardware (camera, credit card reader), PCI bus connect hardware, or hard drive. Anything that can be shown as irregular in device manager, is that interest. There is a lot of moving parts to slow and wrong running. If you need fast / more reliable access, then try the SetupDI API (see) Pinvoke.net can start with C # announcements.

It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I).
