I put a similar result from my scanner next to your result. For the
GPIOs, at least the direction bits are different, so i guess they are
used differently. You may want to write a small test-program for your
scanner, similar to what i did for mine[1], using your usb log. If you
got that to work, you can play around with the gpio pins to figure out
their function. Alternatively, you can take a lot of usb logs and guess
the meaning of the pins.

My scanner(Canon LiDE 35) has these functions, as far as i found out:

pin    function          direction
GPIO1: SCAN button       in
GPIO2: FILE button       in
GPIO3: E-MAIL button     in
GPIO4: COPY button       in
GPIO8: overall power?    out
GPIO9: save power        out
GPIO16: Full resolution  out
GPO17: lamp+home sensor? out
GPO18: extra power?      out

You may find some of these. Especially the "Full/Half resolution"
function should be somewhere.
