A lot depends on what you're trying to connect to. You mention USB - I'm guessing that you're then talking about some form of standard HID device (recognised as some form of input control under Windows)... in which case I can declare myself "out" from a knowledge point of view (it's an interesting area to research.. might have a play)... or you can use a simple serial interface and use the serial/USB interface inherent on just about all Arduino devices to stream encoded control/analogue data over serial/USB to dedicated software running on the PC (I do this a lot to talk to PIs, which then encapsulate data into an ethernet package for transmission on a network). This second option is certainly I can talk to you about.
