What is Batch Script Devices?

Windows now has a better library which can be used in Batch Script for working with devices attached to the system. This is recognized as the device console – DevCon.exe.

Windows driver architects and analyzers can utilize DevCon to check that a driver is introduced and designed effectively, including the correct INF records, driver stack, driver documents, and driver bundle. You can likewise utilize the DevCon orders (empower, handicap, introduce, begin, stop, and proceed) in contents to test the driver. DevCon is a summon line instrument that performs gadget administration works on neighborhood PCs and remote PCs.

Show driver and gadget information DevCon can show the accompanying properties of drivers and gadgets on nearby PCs, and remote PCs (running Windows XP and prior) −

  • Hardware IDs, compatible IDs, and device instance IDs. These identifiers are described in detail in device identification strings.
  • Device setup classes.
  • The devices in a device setup class.
  • INF files and device driver files.
  • Details of driver packages.
  • Hardware resources.
  • Device status.
  • Expected driver stack.
  • Third-party driver packages in the driver store.
  • Search for devices DevCon can search for installed and uninstalled devices on a local or remote computer by hardware ID, device instance ID, or device setup class.
  • Change device settings DevCon can change the status or configuration of Plug and Play (PnP) devices on the local computer in the following ways −
    • Enable a device.

    • Disable a device.

    • Update drivers (interactive and non-interactive).

    • Install a device (create a devnode and install software).

    • Remove a device from the device tree and delete its device stack.

    • Rescan for Plug and Play devices.

    • Add, delete, and reorder the hardware IDs of root-enumerated devices.

    • Change the upper and lower filter drivers for a device setup class.

    • Add and delete third-party driver packages from the driver store.

DevCon (DevCon.exe) is included when you install the WDK, Visual Studio, and the Windows SDK for desktop apps. DevCon.exe kit is available in the following locations when installed.


Syntax

wherein

  • /m:\\computer − Runs the command on the specified remote computer. The backslashes are required.
  • /r − Conditional reboot. Reboots the system after completing an operation only if a reboot is required to make a change effective.
  • command − Specifies a DevCon command.

To list and display information about devices on the computer, use the following commands −

  • DevCon HwIDs
  • DevCon Classes
  • DevCon ListClass
  • DevCon DriverFiles
  • DevCon DriverNodes
  • DevCon Resources
  • DevCon Stack
  • DevCon Status
  • DevCon Dp_enum

To search for information about devices on the computer, use the following commands −

  • DevCon Find
  • DevCon FindAll

To manipulate the device or change its configuration, use the following commands −

  • DevCon Enable
  • DevCon Disable
  • DevCon Update
  • DevCon UpdateNI
  • DevCon Install
  • DevCon Remove
  • DevCon Rescan
  • DevCon Restart
  • DevCon Reboot
  • DevCon SetHwID
  • DevCon ClassFilter
  • DevCon Dp_add
  • DevCon Dp_delete

Examples

Ensuing are some instances on how the DevCon command is used.

The resulting command uses the DevCon DriverFiles operation to list the file names of drivers that devices on the system use. The command uses the wildcard character (*) to indicate all devices on the system. Because the output is extensive, the command uses the redirection character (>) to redirect the output to a reference file, driverfiles.txt.

The resulting command customs the DevCon status operation to find the status of all devices on the local computer. It then saves the status in the status.txt file for logging or later review. The command uses the wildcard character (*) to represent all devices and the redirection character (>) to redirect the output to the status.txt file.

The resulting command allows all printer plans on the computer by specifying the Printer setup class in a DevCon Enable command. The command includes the /r parameter, which reboots the system if it is necessary to make the enabling effective.

The resulting command uses the DevCon Install operation to install a keyboard device on the local computer. The command includes the full path to the INF file for the device (keyboard.inf) and a hardware ID (*PNP030b).

The following command will scan the computer for new devices.

The following command will rescan the computer for new devices.
