[sane-devel] HP 3970 scanner

[Bakay Árpád]

Hi, this is better consumer scanner with 2400 DPI and 48bit colour. The box advertises both 2400 and 48 with LARGE text.
 
My enthusiasm was quickly chilled, when I learned from HP support, that I cannot get 48 bit from windows only 24.
They told that the Mac can read 48 bit, but the only officially supported driver is the one for Windows. Get it?
Let me not entertain you with the ridiculous reasons HP support told me when I simply asked why is it a 48bit colour scanner then?.... 
 
The real reason, as my colleague pointed out is that HP is very bad at writing drivers, and they just simply sell it with the old 24bit Windows drivers....
 
Now I am upset enough to invest some effort myself in getting those bastard 48 bits out of the scanner for Linux. 
 
IF
1.	No one has done it yet.
2.	Someone can give me some practical advice on how to start with that. 
a.	Shall I try to snoop USB on a MAC? (I can get access to it)
b.	Can anyone give me some information on the chipset?
 
In general: what is your impression: can I expect much quality enhancement from a 48 bit consumer-grade scanner, or it should just be considered a marketing trick?
 
 
Regards,
