Could be in Universal Serial Bus Controllers, do you know what the device is called, if so you can just google it. My sister has a program on her computer that lists all your devices, unfortunately its 1.30AM so i can't find out for you, but if your question hasn't been answered by tomorrow morning i will let you know.
EDIT: You could also try out this piece of software to find out your hardware etc;
