Sorry - to find the VEN and DEV information, look under Drivers then scroll to HardwareIDs and it should be there. It might be enough to uninstall teh device then restart the system to see if it can recover. I've had this Code 39 error a number of times and always with the dreaded Toshiba Samsung branded optical drives so TSST might show up somewhere. If it does, in my experience you may as well simply replace it.
