Which module supports USB flash drives in my system?

edit

Under previous versions of Fedora I usually found OHCI, UHCI or EHCI modules when USB sticks were inserted. But now I do not see any of these modules. Can you please point at the module which provides USB stick support? Or is that even a module? Perchance it is now in userspace supported by Mate DE?
