[sane-devel] Neat NM-1000

[Ralph Little]

Hi,
Have you tried cracking it open to see what chips are inside?
 From what I gather from what others say, Genesys chips are usually 
obviously branded as such.

Obviously there are dangers with that so if you do, you obviously risk 
some damage. Disassembly is not always that obvious and you risk 
whatever warranty you have.
Also, if this is expensive and something you rely on, then that is 
something you must consider.

I just had a quick peek into the Genesys sources and it doesn't look 
like there is GL123 support as yet.
It might be something that Povilas is looking into, though.
I had a brief look at the data sheet and it doesn't look massively 
different to the other Genesys stuff I have seen, but then I'm a 
beginner at this game so take that view with a pinch of salt.

Certainly before starting on anything like that, unless I was absolutely 
certain what was in it, I would tend to want to take a look at the 
chippery. You could also take some small USB captures and post them 
somewhere public for people to look at. Someone, somewhere might 
recognise it, or at least confirm that it is somewhat Genesys related.

Cheers,
Ralph
