Need to find a hardware Class GUID

_{Friday, September 30, 2016 5:20 PM}

I'm trying to set up USB postage scale for RemoteFX USB redirection. To do so, I need to know the Class GUID.

Usually, I just connect it to a workstation and look at the properties for the device in Device Manager. But as near as I can tell, this one is not appearing in Device Manager at all. Also looked in MSINFO32.

I have one clue: When I connect the device, this event is logged:

Log Name:      Microsoft-Windows-DeviceSetupManager/Admin
Source:        Microsoft-Windows-DeviceSetupManager
Date:          9/30/2016 10:55:35 AM
Event ID:      112
Task Category: None
Level:         Information
Keywords:     
User:          SYSTEM
Computer:      ComputerName
Description:
Device '10 lb USB Postal Scale' ({6cbfbce5-7bbc-5932-8e23-075b0f333acf}) has been serviced, processed 6 tasks, wrote 34 properties, active worktime was 15692 milliseconds.

Like I say, I can't find '10 lb USB Postal Scale' in DEVMGMT.MSC or MSINFO32. I learned from looking at connection events for known devices that the GUID shown is not the Class GUID; it's the Base Container ID. Is there a way to get Windows to cough up the corresponding Class GUID from this (or any other) information?

TIA

Hi，

We can also find the Class GUID in Setupapi.dev.log under Windows\INF\ folder like this, you can use the device name to find the corresponding GUID:
