Query: Know what kind of card slot you have.

I bought this mouse for my husband for Christmas. We both checked it out rather thoroughly and nowhere do any of the specifications mention that there are different kinds of slots. If you know what you're looking for, you can tell from the pictures but it never occurred to either one of us that it wouldn't fit. The website pictures a USB charger that can be attached but apparently no one sells it. I can't rate this because I can't use it!!!!
