A Universal Serial Bus (USB) host controller is an interface that allows an enabled piece of hardware to interact and communicate with a particular piece of software. ... A USB host controller manages the communication between peripheral devices and the computer system.
I believe the IC you mention (ft230x) is a USB slave only, so you cannot make it act like a USB host (thats what I got from looking throug the datasheet here https://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT230X.pdf) The USB drive is also a USB slave, meaning they will not be able to talk to each other.
I believe you might be looking for a USB host like this one: https://www.ftdichip.com/Products/ICs/FT313H.html (just did a quick google search, don't quote me on this, I think this one needs a lot of GPIO pins to drive) to talk to your usb drive.
