Recommended Posts


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.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.
