Check if USB device is connected

Hi,

I would like to monitor if a certain USB device or any other device showin in the device manager is still connected / available.

Is this somehow possible?

erm...

If anyone is interested in how to check for the presence of a specific USB device just give me a shout and I will upload it to the community.

EDIT:

Well, I'll just share the interesting part here... (You will need to embed this in a custom vbscript monitor)

There are two script arguments you need to pass on, the first will be ${IP} and the second one will be a string that needs to appear in one of the USB devices on that machine, make sure you make it something that is unique to the USB device you want to find! If the string is found in any of the USB Devices of the machine, it will return a Statistic of '1', if it is not found it will return a Statistic of '0'. Hope someone might find it useful :P

strComputer = WScript.Arguments(0)
strUSBDevice = WScript.Arguments(1)
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colDevices = objWMIService.ExecQuery _
    ("Select * From Win32_USBControllerDevice")
For Each objDevice in colDevices
    strDeviceName = objDevice.Dependent
    strQuotes = Chr(34)
    strDeviceName = Replace(strDeviceName, strQuotes, "")
    arrDeviceNames = Split(strDeviceName, "=")
    strDeviceName = arrDeviceNames(1)
    Set colUSBDevices = objWMIService.ExecQuery _
        ("Select * From Win32_PnPEntity Where DeviceID = '" & strDeviceName & "'")
    For Each objUSBDevice in colUSBDevices
        If InStr(objUSBDevice.Description,strUSBDevice) > 0 THEN
    WScript.Echo "Statistic: 1"
    WScript.Quit( SUCCESS )
        End If
    Next
Next
WScript.Echo "Message: USB Device not found!"
WScript.Echo "Statistic: 0"
WScript.Quit( FAILED )

Hello Questionario,
you can use custom windows script to do this using WMI. Some help can be found here: http://blogs.technet.com/heyscriptingguy/archive/2005/03/15/how-can-i-determine-which-usb-devices-are-connected-to-a-computer.aspx

Stumbled across this when trying to do the same. I have done this by running the below command in powershell and make note of the 'caption' of the required USB

gwmi Win32_USBControllerDevice | %{ [wmi]($_.Dependent)} |Sort Description,DeviceID | ft Description,Caption -auto

Then in SAM create a new template, create a powershell component and enter the below, changing <USB device> to the caption we found above.

If ((Get-WmiObject Win32_PnPEntity -filter "name='<USB Device>'" -ComputerName '${IP}' -Credential '${CREDENTIAL}').status = "ok") {

Write-Host "Statistic: 0"

exit 0;

}

Write-Host "Statistic: 1"

exit 1;

I have also uploaded my template to thwack, it is called 'USB License Dongle'

Hi There,

I need to check if there is USB dongle connected to a machine and preferable to get as much details of it.

I was wondering if you managed to retrieve this information using vbs?

Thanks,

Joao
