I have been writing a article about three months ago which detailed how to edit the registry to display previously connected usb devices in the device manager. While this method is still working I found a free software that has exactly the same function. The software is called USB Deview and was developed by one of my favorite software programmers NirSoft. Before I start and describe the security software I would like to point out its use. I work for a company in the financing sector and they have such a strict security protocol that everything has to be routinely checked from time to time.
