    Basically, a poll-driven driver polls the device at a regular, but very small, interval, to see if there's activity. Interrupt-driven drivers wait for an IRQ from the device and respond accordingly.
    Beyond that basic description, I suggest you get yourself a copy of O'REILLY's Linux Device Drivers -- 3rd Edition.
