Logitech GT Force and Gran Turismo 2

Am new to this Playstation/Gran Turismo hype and am in the process of trying, I repeat, trying to figure out which to purchase first....leaning toward the PS1 and GT2. I'm wondering if the Logitech GT Force driving wheel is compatible with the PS1 and GT2 game?....or is it made to plug into the PS2 only...I understand the Logitech has a USB connector. Does both PS1 and PS2 have USB connections?
