To run DevCon commands on a remote computer, the Group Policy setting must allow the Plug and Play service to run on the remote computer. The system selects the most appropriate driver from the INF file based on the hardware ID of the device.
Restart a device The following command uses the DevCon Restart operation to restart the loopback adapter on the local computer. There are no open issues. The following command use the DevCon Rescan operation to scan the local computer for new devices. Find the setup class of a device. The following command uses the DevCon DriverFiles operation to list the file names of drivers that devices on the system use.

Programmable interrupt controller Driver is running. On win7 devcom device classes are not detected automatically, so I end up with two child unknown devices. The syntax for these commands can be either: The following command uses the DevCon HwIDs operation and a device setup class to find the hardware IDs of innstall devices in the Ports device setup class. The command uses the at character to indicate that the phrase is in the device instance ID.
You can use this command to replace signed drivers on the system with alternate drivers for testing or troubleshooting, or to associate the devices with the newest version of the same drivers.
The DevCon source code is also available so that you can examine the methods that DevCon uses to retrieve and change setup and configuration data.
The second subcommand, -MyFilteruses the add-before operator – to add MyFilter. The following command uses the DevCon ListClass operation to list the devices in Net, the device setup class for network adapters. In response, DevCon displays a message indicating that it is added beep to the hardware ID list for the device.
The command does not use any symbol parameters to position the ID. I further built vmulti with WDK 7. Find the setup class of a device The DevCon Stack operation returns the setup class of a device in addition to the upper and lower filter drivers.
