The usb version doesn't come with toe brakes. The toebrakes are a separate add-on.
From what I've read, I figure having the toe brakes and being able to program my joystick/throttle and rudders with foxy is the way to go. I didn't really see any advantage to having a USB rudder. If my joystick goes down, I wouldn't be able to fly with only rudders anyway, at least not enjoyably.
