Miserable speed-up with FireWire vs. USB1.1

Just to make you aware of this.
The full-resolution preview of 6-frame negative strip on my Dimage
Scan Elite 2 takes ~18 min with USB 1.1 connection and ~15 min with
FireWire connection.
The computer: Pentium 4 2400, 512 MB RAM.

Which indicates that the exposure time per frame is the bottleneck, not the
interface.

According to the help file:
You can significantly speed up batch scanning on some scanners by setting
two options so the preview won't be done when you do a scan. To do this, set
the cropping for all the frames, then clear "Crop|Auto position". In
addition, if the "Input|Lock exposure" option is displayed, turn it on and
set "Input|RGB exposure" to either "1" or a value greater than one that
won't overexpose any of the images. (My note: use the Advanced Workflow for
negatives).

Scanning and only saving as Raw will help (lower res preview and scan full
res).
Turning off rotation may help. Turning "Refresh each scan" off will help,
and turning on "Release memory " may help.
