Thanks !

In fact, before starting my work on the D1250U2 scanner, I had a look on
SANE backends hoping that one would be close to mine. Unfortunatly, what
is currently causing me problems is the register list/function of the
SCAN09 ASIC (no datasheet :( ). The protocol in itself is using a little
number of commands (get/set registers, trigger bulk commands, bulk
transfers).
