Detect when a USB keyboard is plugged. (Solved)

[Belini]

Is there any way to know when a USB keyboard is connected to the computer?

I'm not sure why you'd need this, but you could modify this script to tell you when a USB keyboard is added/removed.

$strComputer = "."

Global $objWMIService = ObjGet("winmgmts:\\" & $strComputer & "\root\cimv2")
Global $colDevices = $objWMIService.ExecQuery("Select * From Win32_USBControllerDevice")
Global $strOutput = ""
For $objDevice In $colDevices
    $strDeviceName = $objDevice.Dependent()
    $strQuotes = Chr(34)
    $strDeviceName = StringReplace($strDeviceName, $strQuotes, "")
    $arrDeviceNames = StringSplit($strDeviceName, "=")
    $strDeviceName = $arrDeviceNames[2]
    Global $colUSBDevices = $objWMIService.ExecQuery("Select * From Win32_PnPEntity Where DeviceID = '" & $strDeviceName & "'")
    For $objUSBDevice In $colUSBDevices
        $strOutput &= $objUSBDevice.Description & " = " & $objUSBDevice.PnPDeviceID & @CRLF ; Changed from Description to PnPDeviceID
        ;as this script can be altered to return any property
        ;of the Win32_USBControllerDevice collection.
    Next
Next
ConsoleWrite($strOutput)
