I use a program called "Bus Hound" to log the USB, SCSI and
Firewire commands that are used to talk to scanners. I also
often have documentation on a scanner's basic command set.
The rest is just hard work decoding the commands that the
vendor's software sends to the scanner. For instance, on
the Nikon scanners, I changed the "analog gain" command,
logged the commands from a scan, changed it again, logged
the commands from another scan and then looked to see
what fields in the commands changed.
