[sane-devel] sane-sp15c and Fujitsu 620c: Help needed for plumbing backend t

[m. allan noah]

ahh, now that i look at the avision backend, i see that it only mentions 
scanpartner units up thru the 600, but not the 620.

you could try adding a new block for the 620c down near line 900 of 
avision.c and recompile. just copy the 600 block.

if that does not work, you might try setting the 0 at the end of the block 
to AV_FUJITSU (like the 15c is a few lines above)

i have only done a cursory glance at this code, so it may not work, but 
its is worth a try :)
