[sane-devel] canon_dr and DR-7090C

[m. allan noah]

I assume the missing source was also the case with the 1.0.21 driver?

I don't know how to detect if a canon machine has a flatbed, so it
needs to be added to the code. edit backend/canon_dr.c around line
1137, before the test for the 2580, ad these lines:

  else if (strstr (s->model_name,"DR-7090")){
    s->has_flatbed = 1;
  }

Then rebuild and re-install. That should give you flatbed support, but
this will be the first flatbed supported by the backend, so we might
have some more cleanup to do.
