The aim of this function is to find the serials of all currently

To do this, we first retrieve a list of all devices and place
their serials into a set.
We then retrieve the list of all assets, extract their associated
devices' serial numbers and place them into a second set.
We then obtain the desired result by subtrating the second set from
the first.
