[Genesys] Plustek OpticFilm 7400 v1 bugs

As requested on sane-devel, reporting a few issues with the Genesys driver and the Plustek Opticfilm 7400 v1:

I have scanning basically working with my PlusTek OpticFilm 7400 (which sane identified as a v1).

There are a few minor things I'd love to see fixed. I'm using 1.3.1, which is the latest package version available for Debian Trixie.

Roughly in order of importance:

  • With --mode Gray, any format at any DPI produces a corrupt file. Fixed by (currently open) MR !896 (merged)

  • With --mode Color, JPEG images are corrupt, although other image formats are fine. Fixed by !876 (merged).

  • SANE does not seem to recognize the two buttons on the front of the device (labeled "QuickScan" and "IntelliScan").
