Manufacturer and model is no problem, run something like
scanimage -f '%v: %m,' | tr ',' '\n'

But I think the model ID is not sufficient to be unique because
* For the same model there may be more than one backend activated
  (e.g. 'epson' and 'epkowa') and different backends may require
  different color profiles.
* There may be more than one same model connected.
  Individual models may require different color profiles.

I think you need
- manufacturer name, model name, and model ID
- backend name
- model serial number
