Except most scanners I have looked at max out at shoving 2-3Mb/sec out to
whatever the bus is, because of their internal processing. USB will choke
that back a bit, parallel even moreso (~750k/sec). Even SCSI2 is way
faster than most scanners ever need, so Firewire is complete overkill in
speed terms - but has other things going for it, ease of use etc.
