How to determin if a specific USB Device is currently plugged in?

During installation and prior to running DPInst which has worked fine for us I need to verify if a specific USB device is currently plugged in or not. I was looking at possible solutions and came across...

System::Call "cfgmgr32::CM_Get_Device_ID..."

CM_Get_Device_IDW function (cfgmgr32.h) - Win32 apps

http://msdn.microsoft.com/en-us/library/windows/hardware/ff538405(v=vs.85).aspx

The CM_Get_Device_ID function retrieves the device instance ID for a specified device instance on the local machine. (Unicode)

...but simply have no clue on how to implement this properly and/or if this would even allow me to look for a specific VID/PID. Could you give me some hints on how to do this?

Thank you very much for your assistance.

Is this your USB hardware? Your developers probably know how to detect it...

You can use http://nsis.sourceforge.net/WMI_header

!include WMI.nsh

If you know the Hardware ID (VID: PID) USB Flash, it is possible to determine whether the connected USB flash drive.
${WMIGetInfo} root\CIMV2 Win32_USBHub PNPDeviceID callback_Function

Or to determine the connection, knowing the specific VolumeName
${WMIGetInfo} root\CIMV2 Win32_LogicalDisk VolumeName callback_Function

or use GetVolumeInformation
