What is this USB for?

[tv9285]

Just got a ZhiZhu Android TV and its working fine. Problem is it came with a USB plug in that looks like a flash drive but could be a dongle. Plugging in to my laptop does nothing and from what I can tell plugging it into the the Android TV box does not do anything either. Is it possible it is to link with an external device like keyboard or other? There is nothing in the manual about this.

Thanks,

Post a picture.
Maybe it is a bluetooth adapter, or the receiver for a remote.

Thanks for the reply

I guess I was having brain cramps. It is a mini memory card reader. I wasn't looking closely enough. DUH!!
