In theory the HP74xx should already be supported for over an year now 
... Alas, it is nice to see that all my ongoing efforts (for new and

the only remaining problem?

Could you provide me with the log of a successful flatbed and for the

SANE_DEBUG_AVISION=7 xscanimage 2> log

(Due to the size best send it in private, only.)
