Question: I need to find the GUID for an existing USB device attached to my Windows XP system. How can this be done using WMI or the registry? Or, is there another avenue that I should explore? Thanks.

**Additional Information:**

I need to find the GUID for a specific known device; it is not expected to change. If I need to write a little program, use some tool, or look somewhere in the Windows system to find this information, it's all the same to me.

Answer: 
Control Panel > Device Manager > Right Click on Device > Properties > Details Tab > Change 'Property' to Driver Key > Guid will be displayed in 'value' section
