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). Norbert
