Just an idea, but you could make two versions of the device, say 'dv_device' and 'dv_device1' along with whatever the other required item is, let's call it 'it_item'. dv_device would be a dummy device that wouldn't really do anything, unless you wanted a popup telling the player that they need it_item. dv_device1 would be the real device that does whatever you're looking for it to do.

Make a quest with an always FLAG that checks to see if you haveitem dv_device and it_item. If both conditions are true then it removes dv_device from your inventory and replaces it with dv_device1 (both items would be almost identical, so the only way player would really notice anything is when the cargo hold got rearranged). The biggest drawback to this that I can think of is that if the player got rid of it_item they would still be holding onto dv_device1, which might not make sense if they're supposed to hold onto both for it to work.
