The Device Scanner collects all the data available for each USB device it detects. Typically, however, you should not import all of a device’s data into a policy. In most cases, a combination of the following recommended fields are sufficient to provide accurate matches for a device:
Manufacturer
Product
Friendly Name
Serial Number
Vendor ID
Product ID
The more data fields that you include in a device definition, the more you limit the number of matches for that device. If you include all of the data fields for a scanned device, you can literally isolate the device definition to the specific USB port on the computer where the device was scanned.
For information about editing a scan file to modify the data included in a device definition, see Modifying Device Data.
