CountyIT Posted June 4, 2013 Posted June 4, 2013 I am at a loss. I have a virtial com port installed (COM35). if I look at the properties of it in Device Manage (Hardware IDs) the VID is 403 and the PID is 6001. The actual port number could change simply by unplugging the USB cable and plugging it in to a different USB port. The VID and PID, however, will stat the same. Is there any way to write a script that will look through the WIM (or registry for that fact) and look for the VID and PID and return the resultant ComPort? I.E. If the actual ComPort# changes I can still find the ComPort# based on VID and PID?

Moderators JLogan3o13 Posted June 4, 2013 Moderators Posted June 4, 2013 (edited) I was thinking something like this: $wbemFlagReturnImmediately = "&h10" $wbemFlagForwardOnly = "&h20" $WMI = ObjGet("winmgmts:\\" & @ComputerName & "\root\WMI") $aItems = $WMI.ExecQuery("SELECT * FROM MSSerial_PortName", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly) For $element In $aItems MsgBox(0, $element.Active, $element.PortName & " " & $element.InstanceName) Next Edit: Beat me to it, looks similar Edited June 4, 2013 by JLogan3o13 "Profanity is the last vestige of the feeble mind.

CountyIT Posted June 7, 2013 Author Posted June 7, 2013 Pretty close JLogan3o13. I used "Select * from Win32_PnPEntity" and looked for "FTDIBUSVID_0403+PID_6001" in the DeviceID. Than I could parse the actual COMXX from the Name. That is also pretty much what that link you supplied did Nessie. In both cases the "FTDIBUSVID_0403+PID_6001" is simply a USB to Sertal Converter. There could be a problem if there are two or more of them in the same computer in that you can't be sure what device is on the other end of that USB to Serial Converter. A question.... if there are two or more of these present in a computer how does the WMI know which one was plugged in first... or does it?
