Anyway i found a tool that will benefit you, you can at least configure some restrictions beforehand. This is where you can find Ratool to be of some use.
Ratool or Removable Access Tool is a very simple-to-use portable freeware Application that helps an individual protect his confidential data from being copied by others via a USB. When you download and install the application you are presented with a simple interface that boasts options to either disable USB flash drive access temporarily or access it with restricted permissions or disable the access completely. So, when you first launch the app, you will notice these 3 different toggles.
