Well the way mouse hacks work is that you can store files on a mouse. But making a mouse like this would not be easy. I'm not sure how to make them but I am sure people sell them somewhere. And then of course you would want a better cheat (optional I guess) and they are hard to program etc. Not only that but they would be expensive. There is alrenative options to a mouse (which I prefer) like keyboard or what I use is a USB hub or a splitter. When it's in your pic it looks like it's just a price a hardware but you would program the cheat to open with a button and make sure that the cheat doesn't show anything on injection.
