This policy setting allows you to configure a list of Enhanced Storage devices by manufacturer and product ID that are usable on your computer.
This policy setting only applies to Enhanced Storage devices that support a Certificate Authentication Silo.
If you enable this policy setting, only Enhanced Storage devices that contain a manufacturer and product ID specified in this policy are usable on your computer.
If you disable or do not configure this policy setting, all Enhanced Storage devices are usable on your computer.
The device identifier should be entered in the form "Vendor ID-Product ID" where "Vendor ID" is the Institute of Electrical and Electronics Engineers, Inc. (IEEE) issued organizationally unique identifier (OUI) of the manufacturer and "Product ID" is a string assigned by the manufacturer.
For more information on how to obtain the manufacturer and product ID from the device search for "Enhanced Storage Access" on Microsoft TechNet.
