Hi
i have a small question because for the Canon 4400F, if i look in the
code of the genesys backend ( backend/genesys_devices.c ) i can see:
static Genesys_Model canon_4400f_model = {
"canon-canoscan-4400f", /* Name */
"Canon", /* Device vendor string */
"Canoscan 4400f", /* Device model name */

{16, 8, 0}, /* possible depths in gray mode */
{16, 8, 0}, /* possible depths in color mode */

pixels at 600 dpi*/

in mm (y) */

/* 0 38 76 OK 1200/2400 */

GENESYS_FLAG_NO_CALIBRATION |
GENESYS_FLAG_LAZY_INIT |

GENESYS_FLAG_CUSTOM_GAMMA,
GENESYS_HAS_SCAN_SW | GENESYS_HAS_FILE_SW | GENESYS_HAS_COPY_SW,
100,
100
};
and other that tend to show the model is supported.
but in ./descriptions/genesys.desc we have:
:model "CanoScan 4400F"
:url "/unsupported/canon-4400.html"
:interface "USB"
:usbid "0x04a9" "0x2228"
:status :unsupported
:comment "GL843 based, to be added to genesys backend"
