Hello everyone, thanks in advance for your help!

I am doing a computer forensics project for school and in the items gathered from the "crime scene" there is a Microsoft keyboard with 2 USB cables. There is the factory installed one, and one that is placed through a neatly cut hole in the back of the keyboard and tied with a knot so it won't get pulled out.

There is not a storage device at the other end of the second cord, but the wires are attached to a small white plug (pardon my not knowing the type of attachment) that is the same as the type as the one that the factory installed USB cord is attached to, but it is installed on the underside of the circuit board.

Does anyone know what the purpose of this type of device is?

I've already located and made an image of a small drive that was installed inside of a wired mouse with a "broken" tag on it.

This is quite fun, but the keyboard has me stumped.

Just a hypothesis: It's a denial of service device, intended to make you spend more time than planned on researching unknown hardware, and so lower the overall quality of your project deliverables, and in the 'best' case even make you fail to answer important analysis questions.

Not sure how you would test that hypothesis, though. It would clearly not be of any use to ask the manufacturer about it ...
