The Devices on Computers tab provides a table of individual devices that have been connected to individual computers.
The relationship between one device and one computer counts as a single “attachment” in the table, regardless of how many times the two have been connected and disconnected. If you are concerned about the use of removable devices on a particular computer, the Devices on Computers page provides a way to find out if any such connections exist. You can approve and ban individual devices from this table.
