plustek: Thread: HP2300C not a LM9831 or LM9832 chip based scanner.

Hallo,

i connect a HP2300C USB Scanner and modify the modify the plustek-dev.c 
file (copy the 2200 entries and modify the product/vendor id). Not 
loading the scanner kernel modul;

$> sane-find-scanner -v -v

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Any hints, suggestions or further tests?

Hi,

I think there's nothing more to test! It might be, that the test goes
wrong and the HP2300C does contain a LM983x but I don't think
so. You might want to open the scanner and check the chipset
(at least it was no problem to open the 2200c...)

That's all I can say so far
