[sane-devel] GL646 vs GL646_HP

[Tourneur Henry-Nicolas]

Hello everybody,

I'm running a Scanjet 3690 based on a GL646_HP.
I see that Sane doesn't support this scanner but do have a GL646 support.
So my question is : what's the difference bethween both chipset ?

Where can I find doc about GL646_HP ? (I found some pretty good one for GL646 
but not the HP one).

If some code/driver have to be writen, must it be included into 
genesys_gl646.c (i think), or is it a separate driver ?

TIA.
