  Hi List
  
  I have written a service that detects the insertion of USB mass storage devices. 
  
  In the callback for the DBT_DEVICEARRIVAL I have the device interface name (for example)
  
  pDevInf->dbcc_name: 
  
  \\?\USB#Vid_04e8&Pid_503b#00024444444E0F06#{a5dcbf10-6530-11d2-901f-00c04fb951ed}
  
  From the dbcc_name how do I determine the drive letter on the system that this interface corresponds to?
  
  I have had a look at the Setupapi.lib, however I am just going around in circles and I cannot determine which call based on the information that I have corresponds to my drive(s).
  
  The drive I am testing with presents as two devices a CDROM and USB Storage device in Windows.
  
  Thanks
  
  Stuart
