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.

I've started to test the canon-dr backed with my DR-7090C scanner, with
latest snapshot (libsane-canon.so.1.0.22). ?I'm using xsane V.0.997 and
scanimage V.1.0.21.
ADF Duplex and ADF Front works fine, as does all of the scanner's supported
resolutions, and Color/Grey/Halftone/Lineart.
I'm fortunate that ADF Front and ADF Duplex is working, but neither
xsane nor scanimage provides a Flatbed option. ?I have included a list of
all scanimage options detected. ?There is no flatbed option.
