There is a program called spike4.pl which does that

cat $logfile | perl spike4.pl > $output

Doing that shows that your scanner seems similar to 4200F and 5600F,
maybe GL640 and/or other Genesys chip (?). I don't know the status of
the genesys backend (need to search ML archives) or what
chipsets/scanners are currently supported. But I suppose that would be
the next thing to investigate.
