I've got a Doxie at home. It's an awesome little scanner that converts paper into PDF with a push of a button.
Since I use it with a regular SD Card, importing it into the Mac means taking out the SD Card, inserting it into my Mac and manually opening the Doxie app.
What annoyed me was manually opening the Doxie app each time I inserted the SD Card. But while browsing through some old hard drives I found an old System Preference Plugin made by Flexibits.
It's called Cameras and it allows to map specific Camera's to specific apps.Or, with a twist, it allows me to map the Doxie's SD Card to Doxie.app.
